1. Introduction Congratulations on your purchase of the Rocktron Intellipitch™! The Intellipitch is a 24-bit, MIDI-programmable digital effects processor featuring intelligent, chromatic and reverse pitch shifting algorithms.
2. Quick Setup When selecting a key: = sharp key = flat key Recalling an Intellipitch Preset Storing Modified Parameter Values STEP 1 STEP 1 To recall a stored Intellipitch preset, turn the PRESET control to the desired preset number you wish to recall. The displayed preset will be recalled automatically.
3. Front Panel Some of the controls on the Intellipitch front panel have more than one function, dependent upon the mode that the unit is currently operating in. Please read this section to become familiar with these functions. 1 POWER switch 2 CONFIG button The CONFIG button is used to display the configuration type of the currently recalled preset. The configuration display indicates the effects that the preset executes as well as the order in which they are executed.
8 STORE button This button is used to store values into the Intellipitch memory when modified. See Chapter 8, section C, "Storing Modified Parameters" for more information. 9 PARAMETER SELECT control When monitoring parameter values, this control will scroll through the available parameters under the current effect heading. In the "TITLE EDlT" function, this control will scroll through the available characters in the title that may be edited.
4. Rear Panel 1 R (MONO) INPUT jack This standard 1/4" mono jack provides input to the right channel of the Intellipitch. When using only one input (mono), this jack should be used. 2 L INPUT jack This standard 1/4" mono jack provides input to the left channel of the Intellipitch. When using only one input, this jack should not be used. 3 R OUTPUT jack This standard 1/4" mono jack provides an output for the right channel of the Intellipitch.
7 MIDI OUT/THRU jack This standard 5-pin DIN connector passes on the MIDI information that is received at the MIDI IN jack to other MlDI-compatible devices via a MIDI cable. It also outputs MIDI data when performing a memory dump. Note: Inherently in MIDI there is a limit to the number of devices which can be chained together (series connected). With more than three devices, a slight distortion of the MIDI signal can occur (due to signal degradation) which can cause an error in MIDI signal transmission.

Using the Intellipitch with a keyboard and mixer 8
Using the Intellipitch with a guitar and amplifier !! CAUTION !! Never connect the outputs of a power amplifier or guitar amplifier to the inputs of the Intellipitch. This could damage the Intellipitch. Note: For best results when using the Intellipitch with high gain distortion, always put the Intellipitch after the distortion in the signal chain, never before it.
6. Principle of Operation The Intellipitch provides many parameters to achieve the widest variety of preset sounds possible. The parameters available for a given configuration are divided into sections accessible via the FUNCTION SELECT control. This section will discuss each of the functions that are available which relate to a preset's overall sound. Utilitybased functions, such as MIDI operation, title editing, and factory preset restoration, are described in Chapters 8 and 9.
Mixer Parameters EFFECT LVL This controls the level of the entire effect signal. This control should be set relative to the levels of the Left and Right Direct signals. In configurations which do not include a master Effects Level, the single effect level parameter (Chorus Level, Delay Level, etc.) is considered the master Effect Level control.
HUSH® Function HUSH® is Rocktron's patented single-ended noise reduction system. The HUSH system contained in the Intellipitch is a fully digital implementation of HUSH achieved through Digital Signal Processing (DSP), and is modeled after the latest HUSH design. The low level expander of the HUSH system operates like an electronic volume control.
REVERB Function Reverb, or reverberation, is the continuance of sound within a given room or enclosed chamber after the source of the sound has stopped producing it. More specifically, it is a multitude of echoes so densely spaced that, to the human ear, seem as a single continuous sound. These echoes gradually decrease in intensity until they are ultimately absorbed by the boundaries and obstacles within the room or enclosure.
Reverb Parameters REV INPUT This parameter determines whether the input to the Reverb section is active (passing a signal) or muted (not passing a signal). REVERB LVL This parameter determines the level of the reverb signal at the output relative to the Direct signal and any other effect signals. It is accessible from both the Mixer function and Reverb function parameter lists.
DELAY Function Delay is simply a reproduction of the input signal, originating at a prescribed time (usually expressed in milliseconds, or mS) following the input signal. Delay Types The Intellipitch Hush; Delay; Ducker configuration offers 3 delay types: Stereo, PingPong and 2-Tap. The Stereo delay type provides two separate delays. This delay type is used for applications requiring two discrete delay lines with individual regeneration loops.
16 PAN This allows for the panning of each delay to the left or right output, if desired. The Pan parameter is adjustable from 0 to 100 - where 0 = full left, 100 = full right and 50 = center. DLY TIME These parameters determine the amount of time after a signal is input that the delayed signal will begin to reproduce the input signal. REGEN This parameter is provided for each delay and determines the number of times the delayed signal will repeat itself.
DUCKER Function The process of ducking enables the user to suppress the level of a given signal or effect dynamically, dependent upon the presence of another signal which is desired to be prominent.
VOICE/DLY Function The Voice/Dly function is available only in the following Intellipitch configurations: HUSH;CHORUS ;DELAY;REVERB HUSH;8 VOICE CHORUS;DELAY HUSH;P ITCH SHIFT;DELAY HUSH;P ITCH SHIFT;DELAY;REVERB In each of the above configurations, a separate Voice/Dly function is provided for each chorus or chromatic pitch shift voice that the configuration provides—thus allowing each chorus or pitch shift voice to be configured independently.
PITCH SHIFT Pitch Shifting is used to produce harmony notes (up to four, depending on the current configuration) based on the pitch of the input signal. The Intellipitch provides four different pitch shift configurations—two for chromatic shifting, one for intelligent shifting and one for a special reverse shift effect. Pitch Shift Types Chromatic pitch shifting produces a harmony note that is always a fixed chromatic interval (or number of semitones) above or below the input note.
! Note Pitch shift parameters accessible from Voice/Dly functions refer only to the chromatic pitch shift configurations (Hush; Pitch Shift; Delay and Hush; Pitch Shift; Delay; Reverb), and these parameters are as described below. The pitch shift parameters for the Hush; Intelligent Shift and Hush; Reverse Shift configurations are discussed later in this chapter.

INTELLIGENT SHIFT Function The Hush; Intelligent Shift configuration provides two voices that can be used for intelligent (or diatonic) pitch shifting. Intelligent pitch shifting produces harmony notes that are always generated diatonically within a userspecified key and scale type when the user plays in key. Therefore, any input note played in the prescribed key will result in harmony notes that are also in the proper key.
RANGE The Range parameter can be used to optimize the pitch shifter for the best possible performance based on the current application. The following selections are available: GUITAR BASS WIDE VOCAL Selecting a range that is based on the current application will ensure the smallest delay and the smoothest pitch shift possible. Using the Intelligent Shift Configuration The Mode parameter provides many scales which the Intellipitch can use to determine harmony notes.
Dorian Phrygian Lydian Mixolydian Aeolean Locrian 24
Pentatonic Blues Pent Blues Melodic Minor Harmonic Minor Whole Tone 25
REVERSE SHIFT Function The Hush; Reverse Shift configuration provides two voices that can be used for a special reverse pitch shifting effect. Reverse shifting allows for the delayed pitch sample(s) to be played back in reverse after its prescribed delay time has expired. Reverse Shift Parameters PITCH The Pitch parameter determines the harmony note that the Intellipitch will produce based on the input note. An interval is the distance in semitones between the pitches of two musical tones (e.g.
7. Configurations At the root of each preset’s sound is its configuration. The configuration determines (a) the active effects for a given preset, (b) the adjustable parameters available for a preset, and (c) the order in which the effects are routed in the signal path. The Intellipitch provides 8 highly flexible configurations capable of producing sounds which previously could only be obtained by patching numerous effects together.
HUSH / CHORUS / DELAY / REVERB Configuration This configuration provides HUSH® noise reduction at the input to quiet a noisy input signal (such as from a high-gain guitar preamp) with 4 chorus/delay voices and reverb. Note: 28 When the Delay Time for any voice is set to zero, that voice is taken out of the regeneration loops. This will allow for higher regeneration levels (if needed). It also allows for a more pure sounding decay of the echo when used with other voices set at long delay times.

The current character position to be edited is followed by a flashing decimal. 29 P.
E. Selecting a power on preset The Intellipitch allows you to select the preset that will be recalled each time the unit is turned on. 1 Step 1 2 Turn the PRESET control to the preset number that is to be recalled each time the unit is turned on. 24 PRESET TITLE Step 2 Press the STORE button while the preset number/title or configuration is displayed to save the current preset as the "power on" preset.
F. Tuning your Instrument to the Intellipitch The Intellipitch provides a built in tuner which allows you to tune your instrument to standard pitch, as well as calibrate the Intellipitch to the tuning of your instrument. 1,3 Step 1 Press the front panel TUNER button to initiate the Tuner function. The Intellipitch will briefly display "TUNER ACTIVE".
! Additional ways to access the Tuner function... Creating a Tuner preset In addition to using the TUNER button, the tuner function can also be accessed in the Intelligent Shift configuration by storing the TUNER parameter "IN". Then, each time that preset is recalled, the Intellipitch will display the tuner in place of the preset title and number. To access the functions and parameters of a tuner preset, recall the preset via a MIDI controller two times consecutively.
G. Calibrating the Intellipitch to your Instrument In addition to tuning your instrument to the Intellipitch, the Intellipitch can also be calibrated to the tuning of your instrument. 5 Step 1 3 2 From any Intelligent Pitch preset, ensure that the IPITCH parameter is currently "IN". IPITCH Step 2 IN Turn the FUNCTION SELECT control to "CAL PITCH SHIFT".
9. MIDI Operation A. MIDI Controller Assignments Controller mapping allows for specific Intellipitch adjustable parameters to be mapped (or assigned) to a MIDI controller number for real-time control (via a pitch wheel, expression pedal, etc.) in live performance situations. Any parameter may be assigned to any controller number, from controller 0 through controller 120, or OFF. In the OFF position, the assigned parameter will not respond to any MIDI control change.
Step 5 Turning the PARAMETER SELECT control one step clockwise will display the effect parameter that is currently mapped to the NUMB1 control number. PARA1 Step 6 XXX Turn the PARAMETER ADJUST control to scroll through the available parameters for the current configuration. PARA1 Step 7 EFFECTS LVL After selecting the parameter to be assigned to the NUMB1 controller, press the STORE button to save it. "STORED" will flash briefly on the display.
Step 11 Turn the PARAMETER SELECT control for the last parameter—Controller Lower Limit. LLIM C1 Step 12 Use the PARAMETER ADJUST control to select the parameter value which the controller is not to fall below. LLIM C1 Step 13 XXX -10.0 After choosing a lower limit parameter value, press the STORE button to save it. "STORED" will flash briefly on the display. STORED Notes This entire process is repeated 7 times for a total of 8 controllers (NUMB2, NUMB3, etc.).
B. MIDI Program Mapping Program mapping allows for an Intellipitch preset number to be mapped (or assigned) to a different MIDI program number. The Intellipitch is initially programmed at the factory to access to the lower 128 presets (i.e. program number 1 is mapped to preset 1, 128 to 128, etc.) 3,7 Step 1 4,8 2,5,6 1 To access the Program Mapping function, turn the FUNCTION SELECT control one step past the Controller Assign function.
Step 6 The number on the left of the display is the MIDI program number (or the number sent via a MIDI footswitch, etc.). Use the PARAMETER SELECT control to select the number (1-128) to be mapped to a preset. 110 MAP TO XXX MIDI program number (1-128) Step 7 The number on the right of the display is the preset number to map to (or the preset number that will be recalled when the MIDI program number on the left is sent).
C. MIDI Channel The MIDI Channel function determines the MIDI channel that the Intellipitch receives MIDI commands on. 3 Step 1 4 2 1 Turn the FUNCTION SELECT control to "MIDI Channel". ** MIDI CHANNEL ** Step 2 Turn the PARAMETER SELECT to view the current MIDI Channel. MIDI CHANL Step 3 Use the PARAMETER ADJUST control to select the MIDI channel that the Intellipitch is to receive MIDI commands on. Channels 1-16, OMNI (all channels), or OFF (will not receive MIDI commands) may be selected.
D. MIDI Dump/Load Any or all of the Intellipitch user presets may be dumped to a sequencer or another Intellipitch via system exclusive messages. The information exchanged when performing a MIDI dump consists of the configuration type, parameter values, title characters and controller assignment/limit information. When dumping a single Intellipitch preset into another Intellipitch, the preset being dumped may be loaded into any user preset location on the receiving Intellipitch.
Step 5 Use the PRESET control on the transmitting Intellipitch to select the preset you wish to dump. Any of the user presets (1-80) may be dumped. 17 PRESET DUMP Step 6 Use the PRESET control on the receiving Intellipitch to select the preset location to store the received preset. The preset currently at this location will be overwritten, therefore use caution when selecting the preset location to dump to.
The following information is transmitted when a preset dump is initiated: F0H - Start of Exclusive byte 00H - Manufacturer ID byte 1 00H - Manufacturer ID byte 2 29H - Manufacturer ID byte 3 02H - Product ID byte 28H - Command byte, Preset dump XXH - 200 data bytes, (MSB=0) YYH - Check Sum byte, ("Exclusive or" of data bytes, MSB=0) F7H - End of Exclusive byte Each data byte is a 7-bit value. The first transmitted data byte consists of the lower 7 bits of the first value.
Step 2 Turn the FUNCTION SELECT control on the Intellipitch to the "MIDI DUMP/LOAD" function. This function is available at the most clockwise position of the FUNCTION SELECT control in all user presets. MIDI DUMP/LOAD Step 3 Turn the PARAMETER SELECT control to the "DUMP USER DATA" position. DUMP USER DATA Step 4 Start the sequencer recording. RECORD Step 5 Press the STORE button on the Intellipitch to initiate the user data dump.
Reloading the user memory from a sequencer: Step 1 Connect the MIDI OUT of the sequencer to the MIDI IN on the Intellipitch with a standard MIDI cable. Step 2 Turn the FUNCTION SELECT control on the Intellipitch fully clockwise to the "MIDI DUMP/ LOAD" position. MIDI DUMP LOAD Step 3 Turn the PARAMETER SELECT control to the "LOAD USER DATA" position. The Intellipitch is now ready to receive the user data from the sequencer.
The following information is transmitted when a user data dump is initiated: F0H - Start of Exclusive byte 00H - Manufacturer ID byte 1 00H - Manufacturer ID byte 2 29H - Manufacturer ID byte 3 02H - Product ID byte 2AH - Command byte, Start of user dump, 2BH continue user dump.
E. Factory Restore This procedure allows you to restore the Intellipitch memory to its original condition as it was shipped from Rocktron. ! ! CAUTION ! ! This procedure will permanently erase all user presets and replace them with the original factory presets as shipped from the factory. If you have stored presets which you do not want to lose, make a record of all parameter values before performing the Factory Restore procedure.
