Precautions 3.1 Product liability and extent of the warranty • Please comply to the following advice for using and handling the device. Only by respecting these recommendations can you expect a trouble-free operation of your machine. • As this document is also concerning the product liability and extent of the warranty, it is mandatory to carefully read the whole document and to comply to all of its recommendations.
PAGE 4
3.9 Installation and removal of the EPROM • The exchange of the EPROM in the unit can only be performed when the supply is disconnected. • It is especially dangerous to use tools in and around an open device and wiring carrying mains voltage. After disconnecting the unit, allow some time for the capacitors of the power supply to discharge. • Before removing the EPROM, check carefully which side has a notch on its end, as you will have to insert the new EPROM exactly the same way.
PAGE 5
4 Connection 4.2. MIDI connection All connectors described here are located at the back of the device. 4.2.1. MIDI-IN connection 4.1. Power supply 4.1.1. Version with external transformer • For the export market, the Schaltwerk is to be used with an external power adaptor as it doesn’t incorporate its own integrated mains supply. The connection for the adaptor is indicated “9V DC” and is located to the right of the 5 DIN connectors (MIDI & Sync).
PAGE 6
4.3. Sync-input/output 4.4. CV/Gate connection • To control/synchronize with a square signal. 8 x CV1 (i.e., for pitch or controllers) 8 x CV2 (i.e., for velocity) 8 x Gate • Can be configured as input or output. • Normally, the SYNC connector of the Schaltwerk is configured as an output, i.e., A square signal is available at this connector. Sensibly, the device at the other end must be configured as an input (receiver) on its SYNC connector.
PAGE 7
5 Front panel controls The Schaltwerk sports the following controls: 32 Pattern buttons and LED’s, see page 7-28 • For each of the 8 tracks are a pair of buttons + LED’s: − ON For (de)activation of the track (solo/mute), see page 6-9 “Track mute button”. − Select To mark track(s), see page 6-9 “Track select button”. For each track is a set of 16 buttons + LED’s to (de)activate a Step within that track. See page 6-9 “Step/send state”. 8 Song number buttons + LED’s See page 7-29 Rotary-encoder.
PAGE 8
What is the Schaltwerk 6.2.1 Step/Event Types • The Schaltwerk is a complex sequential event generator for producing not only MIDI data but also Trigger, Sync and CV signals for analog systems. • Generally it will be a Note-Event. The Schaltwerk offers nevertheless the possibility to generate almost any type of meaningful MIDI message.
PAGE 9
6.2.3 Step/Condition • Beside this, there is also for each MIDI event another important aspect, if not the most important stylistic attribute the Schaltwerk offers, namely, the fact whether each prearranged MIDI event will be sent or not. − There is for each step a dedicated LED, indicating whether the related event at that particular place in the row, will be sent (LED on) or not (LED off).
PAGE 10
6.4 Pattern • A complete setting for all 8 tracks, together with their 8 x 16 steps and all related parameters constitute a Pattern. 6.4.1 Pattern number/memory • The Schaltwerk contains 130 pattern storage locations, − 128 non-volatile pattern locations, − 1 Edit-Pattern, and − 1 pattern clipboard 6.4.2 Pattern edit • The pattern to edit is the one that is currently appropriate and can be edited.
PAGE 11
7 Users manual - This means, for example, that track 2 is now selected and its set of parameters is available for editing. 7.1 Powering the unit When no select LED is lit, there is no track selected. The display will then show: • At power-on, the unit will show the following message on its display: SCHALTWERK VX.XX DOEPFER(c)[date] Vx.xx is a synonym. Here should appear the actual software release version implemented.

− The tempo is stored along with each Pattern, and is restored when a pattern is recalled from memory. This can be sometimes annoying, especially in the case of linked patterns (1~2, 1~2~3~4, and Song-Modes), where the tempo will change successively according to each pattern recalled. If the Master-Tempo function is activated, the Pattern related tempo will not be accounted anymore; the currently set tempo will be used instead.
PAGE 15
Track >_2_____m< -->PrgChange:OFF − For Pitch-Bend, the actual pitch inflection value must be set (a value of 64 is the neutral value, and thus equates to no Pitch-Bend) − For Monophonic-Aftertouch is this value unimportant. Access to this parameter was added from version 1.1 upwards. Machines with version 1.0 do have an “OFF” as normal condition. If you are the owner of a version 1.0 machine that you have updated to 1.

them alternatively with the +/- buttons and the rotary encoder. Furthermore, the step position is also shown in the display: − This way, the multiplication of 100% by 100% results in 100%. If one or both of the input values are smaller than 100%, the end result will also be smaller than 100%. − So that a crossed master/slave rule is established through this function. Track >_2_____m< SNo-001:000=C3 These values can also be set independently for each of the 16 steps of a track.
PAGE 17
− This time will elapse after a start message (and only then), when the sequence should normally start. Track >_2_____m< Mode:Down − This delay will not be summed up for each round of the track, otherwise it would increase over time. − So that, while the sequence is running, you can simulate a different start time for each track by changing this value on the fly.
PAGE 18
− For the time being, the Up/Down mode known in arpeggiators, is not available. − Alternate and Pendulum modes go through a complete run, back and forth, before transposing up or down the next progression. 7.4.8 Effect menu • In this menu, various functions of the Schaltwerk are joined, automated and made widely controllable, while offering among the most interesting functions of the machine.
PAGE 19
7.4.8.1. Arpeggiator Modes • To say that the Schaltwerk includes an arpeggiator is not exactly right. • But rather, that the sequence control of the individual tracks is applied to the incoming Note-Events, so that arpeggio-like effects are rendered. • Furthermore, the notes of the arpeggio are directly put into the step note memory location, so that they are immediately processed, and can be individually (de)activated.
PAGE 20
7.4.8.2. Record Step mode 7.4.8.4. Transpose mode • Another mode similar to arpeggio, but offering an entirely different set of effects, is the Record-StepMode. • One further press on the Effect button brings the following message: Track >_2_____m< Record-Step:IN1 • With this mode, the Step Note values and velocities of the previously described tracks will be continuously updated with the notes received from the MIDI input 1.
PAGE 21
7.4.8.6. Chord Trigger 7.4.8.5. Gater • The next press of the Effect-Menu button will bring you the next message: Track >_2_____m< Gater:OFF − To the exception of the Note-Event where a Note-Off will be sent after its related Note-On, all other Event Type will send only their own event data. − If the Gater is activated, with an Event Type other than a Note-Event, at the place where a Note-Off would appear, the same Event Type as the one selected will be sent with a fixed value of zero.
PAGE 22
• The Arpeggio effect and Chord trigger are sharing the same cache memory where note messages to be sent are stored. • Both the Gater and the Chord-Trigger run from the first effects mentioned in the previously explained independent settings. − The Hold effect of the Chord-Trigger also prevents the forwarding of new notes in the Arpeggio effect. • A note change in the Chord-Trigger function will not be effective on the chords already struck, but from the next occurrence onwards.

replaces the actual release number of a version 2 software). The present device will of course receive the appropriate text layout on its front panel. • For all users of previous versions, the update package will include the stickers for the casing. These will be applied at the remaining free locations of the front panel. 7.4.11 Track tools • This menu is here to simplify your work with tracks. • With it, you can: − Copy a track to another − Swap tracks − Initialize a track i.e.
PAGE 24
replace the previous data, as long as no failure occurs during the transfer. 7.4.12 Pattern tools • The four pattern-bank select buttons are used jointly with the 32 pattern buttons to select any of the 128 available patterns. (4 × 32 = 128) You should take note that sending back Dumps of one or several Patterns/Songs into the Schaltwerk while it is running may strongly affect its timing accuracy. It is therefore recommended to stop the sequencer before this operation.
PAGE 25
7.4.14 Song menu Song001 Step:001 Patt.001 -*:002 • The Schaltwerk offers 16 Song memory locations. • When the Song-Mode is desired, one of the Song-Bank or Song buttons must be pressed, and as their LED's are lit, the Song-Mode is now enabled. • To quit the Song-Mode, press one of the active Song or Song-Bank buttons. Both LED’s will go out, and the Song-Mode is now disabled. Caution: To play in Song-Mode the Pattern-Edit buffer is used and overwritten.
PAGE 26
• When the number of iterations is set to 128, another special function is activated. In this case, the pattern will not play 128 times, but instead, will execute a jump. The target pattern is specified with the pattern buttons. Song001 Step:003 Jstep021 -*:128 − the above display means that, at Song-Step 3, a jump to step 21 is taken, and that the song execution will continue from there. Insert-Steps:002 Two empty steps will be inserted at step position 3. 7.4.14.
PAGE 27
The Schaltwerk can however follow an external clock. Pattern:001 -->PrgChange:001 − from MIDI input 1 In this example, the pattern 1 will be called upon reception of Program-Change #1 • Similarly, by pressing a Song button (and Song-Bank button), that specific song can be linked to a given Program-Change. Sync-Intern/Ext. Mode:Ext.MCL1 − from MIDI input 2 Sync-Intern/Ext. Mode:Ext.MCL2 − or from a non-MIDI clock Song:001 -->PrgChange:001 Sync-Intern/Ext.
PAGE 28
• A further Sync parameter related to external MIDI clock control defines the behavior of the Schaltwerk regarding incoming MIDI Continue messages. Sync-Intern/Ext. Mode:Start; Cont 7.5 Typical operation 7.5.1 Loading of pattern in the Pattern edit buffer • At startup, pattern 1 is automatically loaded in the pattern edit buffer. − Only incoming Start messages will play the tracks from their first step.
PAGE 29
• While in Song-Mode, the temporary Song-Edit-Buffer can be overwritten at any time by one of the 16 song presets. − For this purpose, a set of 8 dedicated song buttons is used in conjunction with − 2 Song-Bank buttons to offer the total of 2 × 8 = 16 songs available. • As soon as a song or Song-Bank button is pressed, the related song is loaded in the Song-Edit-Buffer, and, provided that the sequencer is running, it will be processed.
PAGE 30
The following warning is then displayed: 8. Appendix 8.1 Activity display during SysEx reception: • When a pattern SysEx is received faultlessly and written successfully in memory, the display will show the next message: Init Menu! FormatPresetRAM • After pressing the OK button (whose LED is not flashing as usual), the following message appears: Format total RAM FormatPresetRAM Receive Pat:xxx Afterward, the entire memory is erased and initialized.
PAGE 31
9 Troubleshooting • If you experience any of the following difficulties while using the Schaltwerk, look at this troubleshooting guide to help you remedy the problem. • Apparent failures are often related to the particular behavior of the machine. A deeper understanding of the functioning circumvents or avoids these troubles. • If you can not come to a satisfying solution, then maybe are you encountering a real hardware or software problem. 9.
PAGE 32
9.3 The Start, Stop, & Continue buttons “do not react” • All tracks are muted, and no data is sent despite the sequencer is running. • All steps are switched off, and no data is sent despite the sequencer is running. • Due to the effects (Arpeggiator, Gater, Record-Step, …) currently activated, the tracks do not send data because they need incoming MIDI data to play. • Start & End step values are set to the same step position, which if muted will send no data, even if other steps are ON.
