    It meets the required safety standards. Do not use any other power adapter. MODEL D’s Filter Mode switch can be set to either Lo- or Hi-pass for selecting the range of your choice. You can also adjust the Attack, Decay, and Sustain controls WARNING: Please make sure that all units have a proper ground to affect the cutoff frequency with time.

    If you are using the MODEL D in a Eurorack, then this is the main output, as the rear panel DC INPUT - connect the supplied 12V DC power adapter here. The power (53) output connectors are not used.

  • Page 12: Overview

    A quick way of finding out if your external sound system is working, is to turn on the A-440 switch on the MODEL D and adjust the volume control. This will send a constant tone (440 Hz) to your external amplifier and speakers.

  • Page 13: Special Modes

    SysEx commands shown later in this manual. Only set the Poly Chain ON for the first MODEL D. Turn it OFF if you no longer 4.9 Special Modes require a Poly Chain system.

  • Page 14: Calibration

    A-440 Reference The MODEL D A-440 pitch is generated and regulated by the MCU and there is no adjustment required. This set frequency is used as a reference in the following procedure to calibrate OSC1.

  • Page 16 16. Turn on the MODEL D rear panel power switch and check that its Power LED comes on. 17. Do not turn off the MODEL D or let it cool down, until all the calibrations are completed. 18. If the A-440 switch is in the ON position, you should hear the tone in your heaphones or main system if you carefully bring the headphone volume or main volume up.

DC Voltmeter DC Voltmeter 0.001 The diagram below shows the adjustment trimpots that are used in the Oscillator and Octave range calibration procedures.
  • Page 18 The following example shows the use of the popular MIDI Utility "MIDI OX" to send a SysEx message from your computerto the MODEL D to put it into PITCH CV Calibration mode. (This same procedure can be used to send any SysEx message to the MODEL D.)
  • Page 19 9. Then use the LOAD command in the Command Window drop down menu to recall the SysEx message from a file on your computer. 7. The SysEx message will be sent to the MODEL D, and it will then be in its PITCH Calibration mode.

  • Page 22 MODEL D User Manual 5.3 Oscillator Calibration The oscillator calibration is done by following 3 main procedures: OSC1, OSC2, and OSC3. Each procedure is slightly different. OSC1 is calibrated by referring to the A-440 test tone, then OSC2 is calibrated against OSC1, and OSC3 is also calibrated against OSC1.

    Poly Chain If you have multiple MODEL D units, you can connect them in a Poly Chain as shown, so that the first MODEL D plays the lowest note, the second MODEL D plays the second lowest note, and so on, to produce polyphonic sound.

  • Page 30: System Exclusive Commands

    You have to use SysEx to set the Poly Chain ID of the first MODEL D to Device ID=0, the second MODEL D to ID=1, the third MODEL D to ID=3 and so on. All MODEL D units must have the same MIDI channel.

  • Page 32: Eurorack Installation

    The Eurorack case will need its own suitable power supply unit to power the MODEL D synthesizer. A 10-pin connector on the rear of the main PCB of the MODEL D allows the +12 Pins 1 and 2 VDC power supply connection to be made. A 10-pin to 16-pin adapter ribbon No Connection cable is supplied to connect to your power supply.
  • Page 33 The MIDI channel can be changed using MIDI OX or a similar MIDI utility on your computer to send MIDI SysEx commands directly to the MODEL D via the USB MIDI connection. Here is a brief guide to the procedure (see the MIDI SysEx pages in this manual for the actual SysEx codes sent to the MODEL D): 1.
