5. Basic Operation Preset Basics The Prophesy provides 127 unique, stored sounds called presets. Each Prophesy preset remembers effect settings, mixer settings and MIDI information which can be recalled at any time. Presets are instantly recalled when accessed via the front panel PRESET control or a MIDI footswitch.
Preset Pages The initial information that is displayed when a preset is recalled represents the first page for the preset. All remaining parameters for the preset (i.e. mixer parameters, effect parameters, etc.) are located on subsequent pages which are accessible via the front panel PAGE control. Many pages can also be instantly accessed by the corresponding buttons to the right of the display.
Figure 5-2: Basic layout of Prophesy preset pages 15
Adjusting parameters The six controls grouped directly below the display are used to edit the displayed parameter values for each page. All display pages are configured so that each parameter can be adjusted by the control that is located directly beneath it. 122 CHORUS LVL1 ON -2.0 PAN1 LEFT DLY1 DEPTH1 RATE1 88 50 25 Figure 5-3: Each displayed parameter can be adjusted by the control located directly below it.
PROPHESY EFFECTS G Note! Although some effects are automatically assigned to each preset, they do not necessarily have to be active in the signal path (i.e., they can be switched in or out at any time).
Assigning Effects to a Preset The user-assignable Pre Effect and Post Effect pages each begin with a simple page which displays the effect currently assigned to the respective location, as shown in Figure 5-6. The unit will display "EMPTY" if no effect has been assigned to the location, as shown in Figure 5-7.
G Note! It is not necessary to store changes made to a particular page before accessing another page of the same preset, as all changes remain in memory until another preset is recalled. However, it is important to note that any changes made to a preset will be lost if another preset is recalled before those changes are stored.
————————————————————————————————————————————— 2 If you wish to save the new preset to a new preset number, use the PRESET control to select the new preset number. Note that the preset at the currently selected location will be written over when the storing process is completed. If you do not wish to store the new preset at a different preset number, skip this step. Note that the original preset stored at this location will be written over once the storing process is complete.

6. Pages and Parameters This section details all of the pages displayed by the Prophesy and their respective parameters. Note that the pages that are accessible from any given preset is dependent upon which effects are assigned to it, therefore not all pages discussed in this section are accessible from every preset.
PRESET TITLE Page The preset title page is the first page that is displayed when a preset is recalled. The preset title and current channel are displayed on the top line, while the bottom line indicates the effects that are currently assigned to the preset.
HUSH® Page HUSH® is Rocktron's patented single-ended noise reduction system, and is available in all presets. The HUSH system provided in the Prophesy is a fully digital implementation, modeled after the latest analog HUSH design, achieved through Digital Signal Processing (DSP). How HUSH® works The low level expander of the HUSH system operates like an electronic volume control.
HUSH Page 122 HUSH ON H-THRES -44dB GLBOFFSET -3dB HUSH page parameters PARAMETER HUSH DESCRIPTION The HUSH parameter determines whether the HUSH® circuit is active for the current preset. (Off, On) HUSH THRESH The HUSH THRESHOLD parameter determines the level at which downward expansion begins. For example, if the HUSH THRESHOLD was set at -20dB and the input signal dropped below -20dB, downward expansion would begin.
COMPRESSOR Page The compressor allows you to compress the signal prior to the distortion stage. Compression is often used to maintain an even volume level when using clean tones, and is also used to increase sustain when using distorted tones. Compressor Page 122 C-THRESH -22dB C-ATTACK C-RELEASE 16ms .75sec Compressor page parameters PARAMETER C-THRESH The COMPRESSOR THRESHOLD parameter determines the input level (in dB) at which compression will begin.
Application Notes: Compression Compression is most often used when playing with a very clean tone, like in the Clean American or Texas Blues voicings. Since there is very little or no clipping (distortion), the guitar signal will remain very dynamic, which means that there is a lot of variance in volume levels. For example, when you strum a chord or pick a note, it sounds very loud at first and then dies out quickly.
WAH Page The Prophesy includes an internal wah-wah which can either be used as a fixed wah or can be controlled by an expression pedal through continuous control changes. Use of this feature eliminates the need to run long audio cables out to a conventional wah-wah pedal. To set up an expression pedal as a wah-wah pedal, the Prophesy must be configured so that the expression pedal controls the "WAH FREQ" parameter described below. (See "Controller Assignments" in Section 7 for more information.
PREAMP Pages The preamp pages are available in all presets. They are all accessible via the front panel PAGE control, however the PREAMP button provides immediate access to the first preamp page. In addition, turning any of the front panel instant access controls when the preset title is displayed will also instantly access the first preamp page. Preamp Page 1: Gain/Basic EQ Levels 122 GAIN BASS MID TREB PRES MASTER 8.6 6.5 4.0 7.0 5.0 8.
Preamp Page 2: Channel/Voicing 122 CHANNEL VOICING TYPE 1 <--CLEAN AMERICAN V-CN RUNSTAT V-PED 17 OFF 127 Preamp Page 2 parameters PARAMETER DESCRIPTION CHANNEL The CHANNEL parameter allows you to select any of the four preamp channels (1-4) for the current preset. The name of each channel is displayed under the VOICING TYPE heading when selected. Available preamp channels are Clean American, Texas Blues, Vintage British and Mega Drive.
Preamp Page 3 parameters (cont'd) PARAMETER PRELF DESCRIPTION The PRE LOW FREQUENCY level parameter allows you to cut or boost the low frequencies from -15dB to +12dB prior to the distortion stage. This EQ section is a shelving-type. (-15.0 to +12.0) PRELFF The PRE LOW FREQUENCY FREQUENCY parameter allows you to select a frequency band with an upper frequency between 63Hz and 500Hz to be cut or boosted by the pre-LF LEVEL parameter.
Preamp Page 4: Post EQ The Post EQ page allows you shape the tone after it has passed through the distortion stage. These post-distortion EQ parameters have a more pronounced effect on the overall tone than the pre-distortion parameters. 122 PEQ1 PEQ1F PEQ1BW 14.0 125Hz 0.8 PEQ2 PEQ2F - 5.5 1297Hz PEQ2BW 1.3 Preamp Page 4 parameters PARAMETER PEQ1 PEQ1F PEQ1BW DESCRIPTION The POST EQ 1 level parameter allows you to cut or boost a user-selected frequency ±15dB after the distortion stage.
Preamp Page 5: Global EQ The Global EQ page allows you to shape the tone at the output of the Prophesy for all presets. This feature is useful, for example, if you are playing in a venue which provides acoustics that would require readjustment of the EQ parameters of all the Prophesy presets (such as needing less bass or more highs). The Global EQ parameters allow for quickly increasing or decreasing two user-selectable frequencies for all the presets simultaneously when necessary. 122 GEQ1 + 2.
PRE EFFECT page The Pre Effect page allows you to assign any effect that is not already assigned to the current preset to a location in the signal chain that is before the preamp stage. This page displays the effect currently assigned to the Pre Effect location, or "EMPTY" if no effect has been assigned. After an effect is assigned, the Pre Effect page becomes the first display page for that effect. Turning the PAGE control accesses the parameter pages for the assigned effect.
POST EFFECT pages The Post Effect pages comprise three pages which each allow you to assign any effect that is not already assigned to the current preset to a location in the signal chain that is after the preamp stage. These pages each display the effect currently assigned to the respective Post Effect location, or "EMPTY" if no effect has been assigned. After an effect is assigned, each Post Effect page becomes the first display page for that effect.
FLANGER Pages Flanging involves splitting the input signal into at least two individual delayed signals (here referred to as Voice 1 and Voice 2), then modulating these delayed signals so that, when summed back together with the direct signal, phase cancellations will occur at some frequencies while peaks in the response will occur at others. Flanger Page 1: Voice 1 122 FLANGE ON LVL1 PAN1 + 3.
Flanger Page 2: Voice 2 122 LVL2 + 1.5 PAN2 RIGHT DPTH2 65 RATE2 212 REGEN -11.5 Flanger Page 2 parameters PARAMETER DESCRIPTION LVL2 The LEVEL2 parameter determines the volume of Voice 1 relative to Voice 2. (Off to +6.0) PAN2 The PAN2 parameter allows you to pan Voice 1 to the left or right channel. (Left to Right) DPTH2 The DEPTH2 parameter adjusts the amount of modulation of Voice 1 .
CHORUS Pages The Chorus effect in the Prophesy is produced by using up to four delayed signals (referred to here as Voices 1-4), detuning these delayed signals (slightly changing their pitch), then modulating the detune effect so that the amount of pitch detune is constantly varying. Using different detune amounts, modulation rates, modulation depths and pan settings for each delayed signal will produce a greater perceived spaciousness.
Chorus Pages 3 and 4: Voices 3 and 4 122 REGENL OFF LVL3 OFF PAN3 58>R DLY3 0 DEPTH3 RATE3 0 0 Chorus Pages 3 and 4 parameters PARAMETER DESCRIPTION REGEN L (page 3) REGEN R (page 4) The REGENERATION LEFT parameter determines how much of the delayed output signal is fed back into the left input. Note that voice 3 has a REGEN L parameter, while voice 4 has a REGEN R for providing regeneration through the right input. (Off, -42.0 to +6.
ROTARY Page The Rotary effect simulates the classic rotating speaker popular with guitarists and keyboard players. It is designed to mimic the characteristics of the mechanical rotating speaker with added versatility afforded by DSP. Rotary Page 122 ROTSPK RSPEED SLOWSP FASTSP ON SLOW 45 80 ACCEL ROTBAL 100 81>H Rotary page parameters PARAMETER DESCRIPTION ROTSPK The ROTARY SPEAKER On/Off parameter determines whether the Rotary effect is active or bypassed for the current preset.
Application Notes: Rotary The Rotary effect included in the Prophesy has been designed to provide the most realistic simulation of an actual rotary speaker as possible. However, the nature of the rotary effect requires a significantly higher amount of processor power than any of the other effects included in the Prophesy in order to implement it without sacrificing the quality of the effect.
PHASER Page Phase shifting involves splitting the input signal into two signals, then shifting the phase of different frequencies of one signal and mixing it back with the original signal. Phaser Page 122 PHASER> DEPTH 55 RATE RESON STAGES 143 25 4 Phaser page parameters PARAMETER DEPTH The DEPTH parameter determines the modulation depth of the phase shift effect. Higher parameter settings result in the sweep of the filtering effect occurring over a wider frequency range.
PITCH SHIFT Pages Pitch Shifting is used to change the pitch of the input signal to produce a harmony note based on the input signal. The Prophesy allows for 2 harmony voices to be defined for each preset. Each harmony voice can be of any fixed interval—up to one octave above the input signal to two octaves below—and is selected in 20-cent increments. Fine adjustment can be made in one cent (1/ 100th semitone) increments.

DUCKER/DELAY Pages Delay is a repeat of the guitar signal, which will repeat at the time the user sets (typically expressed in milliseconds) after the original guitar signal. The Prophesy provides several parameters to adjust the characteristics of the delay effect. About Ducking The Delay effect also has a built-in Ducker function. The word "ducking" is another way to say that you're turning down the volume level of the delay (or "attenuating" the delay).
Delay Page 1 parameters (cont'd) PARAMETER DESCRIPTION When using the MUTE "POST" setting, the Delay IN/OUT function will start and stop the guitar signal at the delay effect's output. This will produce the following results: When you switch the delay "OUT" while you're playing, the delayed signal will suddenly be chopped off and will no longer be heard. The delay effect's input, however, is still receiving signal.
Delay Page 2: Damping/Ducker 122 HFDAMP DUCK SENS ATTN REL PRE ON -36.0 -23.0 5 Delay Page 2 parameters PARAMETER DESCRIPTION HF DAMP The Delay HIGH FREQUENCY DAMPING parameter controls the amount of high frequency content in the delayed and regenerated signals. Higher amounts of damping will result in less high frequency information in the delayed signal. Application Note: Using little or no High Frequency Damping will render a perfect, mirror like delay.
TREMOLO Page The Tremolo effect continuously varies the volume of the signal at a rate and depth defined by the user. Tremolo Page 122 TREM> T-DPTH T-RATE T-SHAPE 60 103 TRIANGLE {TREMOLO} PST-REV Tremolo page parameters PARAMETER 48 DESCRIPTION T-DPTH The TREMOLO DEPTH parameter determines the amount of modulation for the Tremolo signal. Lower depth settings produce more subtle tremolo effects, while higher settings will result in a more extreme tremolo effect.
REVERB Pages Reverb is a multitude of echoes that are spaced so close together that, to human ears, seem as a single continuous sound. These echoes gradually decrease in intensity until they are ultimately absorbed by the boundaries and obstacles within a room.
Reverb Page 1: 122 R-PAN R-DEC HFDMP L-FRQ REVTYPE L<29 30 88 17 HALL A Reverb Page 1 parameters PARAMETER NAME R-PAN The REVERB PAN parameter allows you to pan the direct input signal to the reverb section to the left or right—thus allowing for only the left or right channel to be reverberated when used with the Dual reverb type, or, for one channel to be reverberated to a greater degree than the other.
Reverb Page 2: 122 PREDLYL PREDLYR 55 100 GATE G-DEC G-THR HOLD ON 17 -26.0 50 Reverb Page 2 parameters PARAMETER NAME DESCRIPTION PREDLY L The PREDELAY LEFT parameter determines the length of time after a signal is input to the Prophesy that the left channel signal will be input to the reverb section. Delaying the reverb signal provides greater separation of the input and reverb signals, and helps to increase the perceived size of the Room, Hall or Stadium.
SPEAKER SIMULATOR Page The SPEAKER SIMULATOR function is available in all presets, and provides a realistic approximation of a miked speaker cabinet when connecting the Prophesy directly to a mixing board, recording system or other full range system using the rear panel RECORDING OUT jacks. Speaker Simulator Page 122 SPEAKER>> SPKRTYPE SIMULATOR> 12 INCH MICPOS REACTANCE +8.0 +3.
MIXER Pages The Mixer parameters are included in all presets. However, the parameter values stored in these pages pertain only to the currently-recalled preset. This internal digital mixer occupies five pages, and allows you to control the signal levels pertaining to each preset's effect configuration. Mixer Page 1: Pre Effect Mix Levels 122 (PRE MIX) (PRE EFX OUT) (EFFECT USED) 57>E - 3.
Mixer Page 2: Post Effect 1 Mix Levels 122 (PST1 EFX 1 OUT) (EFFECT USED) + 1.5 DUCKERDELAY Mixer Page 2 parameters PARAMETER PST1 EFX 1 OUT EFFECT USED DESCRIPTION The PST1 EFX 1 OUTPUT parameter determines the output level of the effect that is assigned to Post Effect 1. The EFFECT USED parameter displays the name of the effect that is currently assigned to the Post Effect 1 location. Mixer Page 3: Post Effect 2 Mix Levels 122 (PST2-IN MIX) (EFX 2 OUT) D<40 -13.
Mixer Page 4: Post Effect 3 Mix Levels 122 (PST3-IN MIX) DIRECT (EFX 3 OUT) OFF (EFFECT USED) EMPTY Mixer Page 4 parameters PARAMETER PST3-IN MIX EFX 3 OUT EFFECT USED DESCRIPTION The PST3-IN MIX parameter determines how much of the signal applied to the Post Effect 3 effect is direct signal, and how much is effect signal. (100% Direct to 100% Effect) The EFX 3 OUTPUT parameter determines the output level of the effect that is assigned to Post Effect 3. (Off, -42.0 to +6.
Mixer Page 5: Reverb Mix Levels 122 REV IN REVOUT DIR 62>E - 5.5 - 1.0 DPAN L<37 OUTPUT PLEVEL STEREO 25 Mixer Page 5 parameters PARAMETER REV IN The REVERB INPUT parameter determines how much of the signal applied to the reverb section is direct signal, and how much is effect signal. (100% Direct to 100% Effect) REV OUT The REVERB OUTPUT parameter determines the output level of the reverb effect. (Off, -42.0 to +6.
Application Notes: Reverb Mixing The DIR (Direct) parameter actually controls the volume of the DRY guitar signal (with no effect) at the output. This can become very useful when attempting to get a wetter effect sound — rather than cranking up all your effects levels, simply turn down the DIR parameter to remove some dry guitar signal. The result will be thicker, richer sounding chorus, rotary, flanger, etc. The OUTPUT control is global, which means that it effects all presets.
CONTROLLER Pages Controller assignments allow for specified Prophesy parameters to be mapped (or assigned) to a MIDI controller for real-time control by an expression pedal or by the controller on/off buttons of a MIDI foot controller. In addition to 120 MIDI control numbers, you may assign the Prophesy's ADSR (Attack/Sustain/Decay/Release) control effect to any parameters with these controller assignments (ADSR is discussed further in Section 7, Using the ADSR).
Controller Pages 122 ( 1 ) CNTNUM PARM 14 PITCH1 UPLIM +300 LOWLIM -200 Controller page parameters PARAMETER (1) DESCRIPTION This number indicates the controller that is currently being edited. CNTNUM The CONTROLLER NUMBER parameter is used to select a controller number for the current controller to respond to. (0 to 120, ADSR) PARM The PARAMETER parameter determines the Prophesy parameter that is to be controlled by the current controller.
TAP BUTTON Page The Tap Button function allows for delay times and tremolo rates to be set by tapping the front panel TAP button, by a momentary footswitch connected to the rear panel, or by a control button on a MIDI foot controller like the Rocktron All Access. Obviously, this is very handy for quickly getting the proper Delay times and/or Tremolo rates for different song tempos. The Tap Button page determines which effects that the Tap function will operate on.
Tap Button Page 122 TAPBTN QUANT BOTH 1/4 NOTE T-CTRNUM 15 T-LED OFF Tap Button page parameters PARAMETER DESCRIPTION TAPBTN The TAPBTN parameter allows you to select whether the front panel Tap button, momentary footswitch, or MIDI controller affects the Delay time, the Tremolo rate or both simultaneously. (Delay, Trem, Both) QUANT The QUANTize parameter determines how the Tap function sets the delay time and the tremolo rate.
MIDI Pages The MIDI pages provide numerous MIDI setup options. These pages allow you to set MIDI send and receive channels and configure MIDI program changes. MIDI Page 1: MIDI Channels 122 MIDI RX TX 1 1 REMOTE TITLE ON ON REM ID 12 MIDI Page 1 parameters PARAMETER DESCRIPTION MIDI RX This parameter sets the MIDI channel that the Prophesy will receive MIDI commands on.
MIDI Page 2: MIDI Program Mapping 122 PRGCHG MAP RECV 33 RECALL 58 MIDI Page 2 parameters PARAMETER DESCRIPTION PRG CHG The PRG CHG parameter determines how the Prophesy will react to incoming MIDI program change commands. When set to "OFF", the Prophesy ignores all incoming MIDI commands. When set to "ON", program changes are executed exactly as they are received. "MAP" recalls the preset set by the RECALL parameter when the program change indicated by the RECV parameter is received.
TITLE EDIT Page The Title Edit page looks just like the preset title page, however it does not display the assigned effects for the preset on the second line. In addition, a flashing cursor indicates the current character position of the title to be edited. For more information on editing a preset title, refer to "Naming Presets" in Section 7.
PRESET UTILITY Page The Preset Utility page provides various preset-related functions, including dumping a single preset, dumping all Prophesy presets and restoring one or all presets to their original condition as shipped from the factory. Preset Utility Page 122 PRESET UTILITY PRESETDUMP Preset Utility page parameters PARAMETER PRESET UTILITY DESCRIPTION This parameter is used to select the desired function to perform. Preset Dump, Dump All, Preset Reinit or Factory Reinit may be selected.
7. Using the Prophesy Selecting a preset The Prophesy provides 127 presets, any of which are immediately recalled when selected with the PRESET control. ——————————————————————————————————————————————————— 1 Selecting a preset is a one-step process. To select a preset, turn the PRESET control until the desired preset number is displayed.
Storing modified presets A modified preset must be stored in order for the changes that have been made to be activated the next time the preset is recalled. ——————————————————————————————————————————————————— 1 To save any changes that have been made to a preset, press the STORE button once to initiate the storing procedure. The Prophesy will display "SELECT DESTINATION PRESET". This allows you to store the modified preset into a new location and save the original preset at its present location.
Naming presets The Prophesy display provides up to 20 characters that can be used to configure a title (or unique name) for each preset. ——————————————————————————————————————————————————— 1 Use the PAGE control to access the Title Edit page. (The Title Edit page looks just like the first preset page, but without the assigned effects displayed).
——————————————————————————————————————————————————— 4 Repeat steps 2 and 3 as many times as is necessary until the desired preset title is displayed. G Note The GAIN and MASTER controls were selected as a quick and convenient twohanded method to perform title editing — where the left hand moves the cursor and the right hand edits the character.
Using Controller assignments Controller assignments allow for specified Prophesy parameters to be mapped (or assigned) to a MIDI controller for real-time control by an expression pedal or by the controller on/off buttons of a MIDI foot controller.
——————————————————————————————————————————————————— 3 Use the control labeled “MID” to select the Prophesy parameter that is to be controlled by the MIDI controlling device. The MID control scrolls through all available Prophesy adjustable parameters. ( 1 ) CNTNUM PARM UPLIM LOWLIM 7 G Reversing upper and lower limit settings The upper and lower limit parameter values can be reversed, so that the upper limit parameter actually holds a lower value than the lower limit value.
Using ADSR What is ADSR? ADSR stands for Attack/Decay/Sustain/Release. The advanced ADSR function featured in the Prophesy provides a powerful degree of control over any user-specified parameter while playing. The Prophesy's ADSR function operates differently than previous ADSR circuits1, as it utilizes Rocktron's patent-pending pluck detection to trigger the ADSR function as you play.
Figure 7-1 is a graph of a typical waveform that the ADSR function might generate, where the line which moves across the graph represents the value of the assigned Prophesy parameter after a string is plucked. Here you can see the role that each parameter plays in determining ADSR operation. Figure 7-1: Typical ADSR waveform ADSR can be used with any Prophesy parameter. One of the many potential uses for ADSR is the simulation of a wah pedal being pressed each time a string is plucked.
——————————————————————————————————————————————————— 2 Use the control labeled “BASS” to select the controller number that will be assigned to Prophesy controller page ( 1 ). To set up a controller assignment to be used with ADSR, this parameter value must be set to "ADSR" rather than a typical controller number. The "ADSR" controller is located one click past control number "120".
——————————————————————————————————————————————————— 5 Use the control labeled “PRESENCE” to select the lower limit, which is typically the lowest parameter value which the parameter will not fall below via controller changes sent via ADSR. However, since we are reversing the upper and lower limits for this application, set this value to 2600Hz.
——————————————————————————————————————————————————— 9 Set up the ADSR page for the preset Use the PAGE control to access the next page, which displays the ADSR parameters. G ADSR ATTACK OFF 0 DEC S-TIME S-LVL R-TIME 0 0 0 0 The Input Meter and ADSR When the ADSR page is displayed, the front panel Input meter changes functions and instead displays ADSR levels. ——————————————————————————————————————————————————— 10 Use the GAIN control to set the ADSR function "ON".
——————————————————————————————————————————————————— 13 Use the TREBLE control to set the S-TIME (Sustain Time) parameter, or the length of time in which the WAH FRQ parameter will hold the value set by the S-LVL parameter. ADSR ATTACK ON 19 DEC S-TIME S-LVL R-TIME 53 14 0 0 ——————————————————————————————————————————————————— 14 Use the PRESENCE control to set the S-LVL (Sustain Level) parameter, which defines the value that the WAH FRQ parameter will hold at for the length of time defined by S-TIME.
Figure 7-2: Graphical representation of example settings What happens when a note is plucked? Referring to Figure 7-2, upon the pluck of a string, the WAH FREQ parameter starts at its lower limit value of 2600Hz and gradually increases to its upper limit value of 310Hz (remember, the upper and lower limits have been reversed in this example) over a period of 19 milliseconds. The signal then decays from the upper limit value (310Hz) to the value set by the S-LVL parameter over a period of 53ms.
Using the Tap Button The Prophesy's Tap Button function allows you to set delay times and/or tremolo rates on-thefly (while playing), either by tapping the front panel TAP button, by a momentary footswitch connected to the rear panel, or by a control button on a MIDI foot controller like the Rocktron All Access. When activated, the TAP function instantly changes the current delay time/tremolo rate settings based on the length of time between any two taps that are less than one second apart.
Setting up MIDI Program Changes MIDI program changes allow for different MIDI program numbers to be assigned to Prophesy preset numbers. For example, MIDI program #58 can be mapped to Prophesy preset #33. Then, when program #58 is selected from a MIDI transmitting device (such as a Rocktron All Access foot controller), preset #33 will be recalled on the Prophesy. The preset/program change mapping is shipped from Rocktron at a one-to-one correspondence (i.e.
——————————————————————————————————————————————————— 3 Use the control labeled “BASS” to select the MIDI program change number to be assigned to a selected preset. PRGCHG RECV RECALL MAP 58 1 ——————————————————————————————————————————————————— 4 Use the control labeled “MID” to select the preset that the specified incoming MIDI program change will be mapped to.
Setting MIDI Channels The Prophesy can receive MIDI commands from other MIDI transmitting devices. In order for this function to operate properly, the Prophesy's MIDI receive channel must be set to correspond to the MIDI channel that the other devices are transmitting MIDI messages on. This section discusses how to set the MIDI receive channel. ——————————————————————————————————————————————————— 1 Use the PAGE control to access the first MIDI page, which looks like the page below.
——————————————————————————————————————————————————— 4 Store the new settings as described under the subheading entitled “Storing modified presets” earlier in this section.
Remote control from All Access The Rocktron All Access MIDI footswitch can be configured to act as a dedicated remote control for the Prophesy — allowing direct access to specific Prophesy features and parameters from the footswitch at any time.
——————————————————————————————————————————————————— 2 Configure the Prophesy for remote access: Use the PAGE control to access the first MIDI page, which looks like the page below. MIDI RX TX 1 1 REMOTE TITLE REMID OFF OFF 0 ——————————————————————————————————————————————————— 3 Use the control labeled "MID" to enable Remote mode operation.
Dumping and Loading Prophesy Data Any or all of the Prophesy presets can be dumped to a sequencer or another Prophesy via system exclusive messages. The information exchanged when performing a MIDI dump or load consists of parameter values, title characters and controller assignment/ limit information. When dumping a single preset into another Prophesy, the dumped preset can be loaded into any preset location on the receiving unit.
