Controls
MIDI Section
- USB PORT – This USB Type B jack allows connection to a computer. The MODEL D will show up as a class-compliant USB MIDI device, capable of supporting MIDI in and out.
- USB MIDI IN – accepts incoming MIDI data from an application.
- USB MIDI OUT – sends MIDI data to an application.
- MIDI IN – This 5-pin DIN jack receives MIDI data from an external source. This will commonly be a MIDI keyboard, an external hardware sequencer, a computer equipped with a MIDI interface, etc.
- MIDI THRU – this 5-pin DIN jack is used to pass through MIDI data received at the MIDI INPUT. This will commonly be sent to another MODEL D synthesizer to run a Poly Chain or to a drum machine assigned to a different MIDI Channel.
Controllers Section - OSC3/FILTER EG – switch between OSC 3 or the Filter Envelope as a modulation source.
- GLIDE – adjust the amount of Glide (Portamento) between notes on the keyboard.
- TUNE – adjust the frequency of oscillators 1, 2, and 3. (OSC3 is not affected if the OSC3 CONTROL switch is off.)
- OSCILLATOR MODULATION – when ON, the three oscillators are modulated by the modulation mix, set by the MOD MIX knob.
- MOD MIX – the modulation mix between OSC3/Filter EG and Noise/LFO.
- NOISE (MOD SRC)/ LFO – switch between Noise (or external modulation source) or Low Frequency Oscillator (LFO) as a modulation source.
- MOD DEPTH – Adjust the modulation depth from off to maximum. The modulation depth can also be adjusted using the modulation wheel on a MIDI keyboard.
- WAVE SHAPE – select the LFO wave shape from either triangular or square wave.
- LFO RATE – adjusts the frequency of the LFO.
Oscillator Bank Section - OSC 3 CONTROL – When ON, the frequency of Oscillator 3 will vary with the keyboard. When OFF, the keyboard, Pitch wheel, and Modulation wheel will not affect SC3.
- FREQUENCY RANGE – select from six frequency ranges of Oscillator 1, 2, or 3.
- FREQUENCY ADJUSTMENT – Adjust the frequency of Oscillator 2 or 3.
- WAVE SHAPE – select the wave shape used for Oscillator 1, 2, or 3 from: triangular, triangular/ sawtooth (OSC 1 and 2), reverse sawtooth (OSC 3), sawtooth, square, medium pulse, and narrow pulse.
- MOD SOURCE (INPUT) – allows connection of an external modulation source. If nothing is connected here, then the internal Noise generator is available as a modulation source.
- OSC 1V/OCT (INPUT) – This input allows the frequency of the three oscillators to be adjusted by an external control voltage (1 Volt input increase will increase the frequency by one Octave).
- LFO CV (INPUT) – allows control of the LFO frequency by an external control voltage.
Mixer Section - VOLUME – the volume of Oscillator 1, 2, or 3.
- ON/OFF – select the sources to play from OSC 1, OSC 2, OSC 3, Noise, and External Input, or any combination of these 5 sources.
- NOISE VOLUME – Adjust the level of the internal Noise source.
- WHITE/PINK – switch the internal Noise source from Pink noise to White noise.
- OVERLOAD – indicates when the audio levels of the mix are overloading the mixer section.
- EXT IN VOLUME – Adjust the level of any external source playing into the external Input. If nothing is connected to the external input, then instead of any external audio coming in at this point, the main MODEL D output is automatically connected here. This creates a feedback path from the output back into the mixer section, to get extra phat bass or extra crunch. In this case, the EXT IN volume control will adjust the level of the incoming main audio fed back into the mixer section.
- LFO Triangular (OUTPUT) – outputs the internal LFO triangular-wave signal.
- LFO Square (OUTPUT) – outputs the internal LFO square-wave signal.
- EXT (INPUT) – connect any external line-level audio source to this 3.5 mm input. If nothing is connected here, then the main audio output is internally connected to this external input.
- MIX (OUTPUT) – outputs the final mix from this Mixer section.
Modifiers Section - DECAY – when ON, the signal will decay during the time set by the DECAY TIME knob after a note or external trigger is released. When OFF, it will decay immediately after a note or external trigger is released.
- LOUDNESS DECAY – affects the decay of volume level of the Loudness section.
- FILTER DECAY – affects the decay of the cutoff frequency of the Filter section.
- KEYBOARD CONTROL – these switches vary the effect of the keyboard tracking, where the filter section is affected by the pitch of note played.
- Switch 1 and 2 OFF – no keyboard tracking effect
- Switch 1 and 2 ON – maximum effect
- Switch 1 ON (only) – 1/3 of maximum effect
- Switch 2 ON (only) – 2/3 of maximum effect.
- FILTER MODULATION – when ON, the filter section is modulated by the modulation mix, set by the MOD MIX knob.
- FILTER MODE – select the filter between Low-pass and High-pass.
- LOUDNESS CONTOUR – these 3 knobs adjust the overall shape enveloping the audio after it has passed through the mixer section and filter section. The controls affect the change in volume (loudness) level with time.
- ATTACK –Adjust the time it takes for the signal to reach a maximum level after a note is played.
- DECAY TIME – Adjust the time for a signal to decay down to the sustain volume level after the attack time is over. If the LOUDNESS DECAY switch is ON, this is also how long it takes to decay to minimum once a note is released.
- SUSTAIN – adjust the volume level that the signal is sustained after the attack time and initial decay time have been reached.
- FILTER ENVELOPE CONTROLS – these 3 knobs adjust the overall shape enveloping the filter section. The controls affect the change in cutoff frequency with time.
- ATTACK – Adjust the time for the cutoff frequency to increase from its set value and reach the frequency set by the AMOUNT OF CONTOUR control.
- DECAY TIME – Adjust the time for the cutoff frequency to decay down to the sustain frequency after the attack time is over. If the FILTER DECAY switch is ON, then this decay time is also how long it takes to decay from the sustain frequency once a note is released.
- SUSTAIN – adjust the cutoff to a frequency which is sustained after the attack time and initial decay time have been reached.
- FILTER CONTROLS – The filter can be low-pass or high-pass, depending on the setting of the FILTER MODE switch. In low-pass mode, audio frequencies above the cutoff frequency are attenuated. In high-pass mode, audio frequencies below the cutoff frequency are attenuated.
- CUTOFF FREQUENCY – adjusts the cut-off frequency of the filter.
- FILTER EMPHASIS – adjusts the amount of volume level boost (resonance) given at the cut-off frequency.
- AMOUNT OF CONTOUR – adjusts the amount of frequency shift given to the cutoff frequency.
- CUT CV (INPUT) – allows connection of a control voltage to control the cutoff frequency.
- FC GATE (INPUT) – allows an external trigger voltage to be applied to trigger the filter contour.
- FILT CONT (OUTPUT) – outputs the filter contour.
- LC GATE (INPUT) – allows an external trigger voltage to be applied to trigger the loudness contour.
- LOUD CONTOUR (OUTPUT) – outputs the loudness contour. Output Section
- A-440 – Use this to turn on an output tuning signal of 440 Hz concert pitch. This switch can also be used to enter various modes during turn-on (see the Getting Started section of this manual for more details).
- POWER – This LED shows when power is applied and the synthesizer is turned on.
- VOLUME – Adjust the overall volume level of the synthesizer output.
- VOLUME (HEADPHONE) – Adjust the overall volume level of the phone’s output.
- PHONES – connect your headphones to this 3.5 mm TRS output. Make sure the headphone volume is turned down before putting on headphones.
- ON –Use this to quickly turn on or mute the main audio output of the synthesizer.
- LOUD CV (INPUT) – allows connection of an external control voltage to control the Loudness Contour.
- MAIN (OUTPUT) – use this 3.5 mm TRS connection to output the main audio output. Typically it is patched to an audio input of the MODEL D or the audio inputs of other modular synthesizer equipment. If you are using the MODEL D in a Eurorack, then this is the main output, as the rear panel output connectors are not used.
Rear Panel - MAIN OUTPUT – connect these 1/4″ TRS outputs to the inputs of your external equipment as follows (note that they are both Mono, and not left/right):
- LOW – This instrument-level mono output can connect to the instrument-level inputs of guitar amplifiers or mixers, for example.
- HIGH – this line-level mono output can connect to the linelevel inputs of mixers, keyboard amplifiers, or powered speakers for example.
- MIDI CHANNEL – these 4 switches allow you to set the MIDI Channel
number from 1 to 16. The MIDI channel can also be changed using MIDI SysEx commands, as shown in the MIDI SysEx tables later in this manual. (This method is used when the MODEL D is housed in a Eurorack, and these switches are no longer present.) - POWER – turn the synthesizer on or off. Make sure all the connections are made before turning on the unit.
- DC INPUT – connect the supplied 12V DC power adapter here. The power adapter can be plugged into an AC outlet capable of supplying from 100V to 240V at 50 Hz/60 Hz. Use only the power adapter supplied.
Getting started
OVERVIEW
This ‘getting started’ guide will help you set up the MODEL D analog synthesizer and briefly introduce its capabilities.
CONNECTION
To connect the MODEL D to your system, please consult the connection guide earlier in this document.
Caution: Do not overload the 3.5 mm inputs. They can only accept the correct level of voltages as shown in the specification tables. The 3.5 mm outputs should only be connected to inputs capable of receiving the output voltages. Failure to follow these instructions may damage the MODEL D or external units.
SOFTWARE SETUP
The MODEL D is a USB Class Compliant MIDI device, and so no driver installation is required. The MODEL D does not require any additional drivers to work with Windows and MacOS.
HARDWARE SETUP
Make all the connections in your system. Use the rear panel MIDI switches to set the MODEL D to a unique MIDI channel in your system. Connect an external MIDI keyboard directly to the MODEL D MID IN 5-pin DIN type input. Apply power to the MODEL D using the supplied power adapter only. Ensure your sound system is turned down. Turn on the MODEL D rear panel power switch.
WARM UP TIME
We recommend leaving 15 minutes or more time for the MODEL D to warm up before recording or live performance. (Longer if it has been brought in from the cold.) This will allow the precision analog circuits time to reach their normal operating temperature and tuned performance.
INITIAL SETUP
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.
MIXER SECTION
The MODEL D has three oscillators, an internal Noise generator, and an external source input. Each of these, and any combination, is used by the MODEL D to generate sound. The Mixer section allows you to turn each of these sources on or off and adjust the volume of each to create an overall mix. Start by turning on the top switch for Oscillator 1, and turn off the others. Adjust the volume control of Oscillator 1. In the Output section, adjust the main volume. Now, if you play a note on your MIDI keyboard, you should hear the sound of Oscillator 1 only. Turn on other oscillators and/or noise and adjust their volume controls to create a mix.
OSCILLATOR SECTION
In the Oscillator section, adjust the Range knob and you will hear the sound of the various octaves. Adjust the wavetype and listen to the differences. The oscillator modulation switch allows the oscillator frequency to be modulated by the modulation mix. The OSC 3 switch allows its frequency to be affected by, or be independent of, the notes played on the keyboard and the modulation and pitch wheels.
Note: The TUNE knob and OSCILLATOR-2 and -3 FREQUENCY knobs are marked in units of semi tones as a general guide.
FILTER SECTION
Play with the Cutoff Frequency, Emphasis, and Contour, and listen to their effects on the sound. Adjust the Attack, Decay, and Sustain; they affect the cutoff frequency with time, while a note is played. The filter decay switch affects the decay after a note is released. The 2 keyboard switches affect how much the filter is affected by the frequency of notes that are played. If the filter modulation switch is ON, then the filter section is modulated by the modulation mix.
LOUDNESS CONTOUR SECTION
In this section, adjust the Attack, Decay, and Sustain; they affect the overall level with time, while a note is played. The loudness decay switch affects the decay in level after a note is released.
CONTROLLERS SECTION
First set the 2 switches to choose from internal LFO or internal Noise, OSC 3 or the filter envelope, and then use the MOD MIX knob to vary the mix between them. You can experiment by first setting the switch to OSC 3, and turning the MOD MIX knob to OSC 3. Then set the Oscillator 3 range control to LO, and the Oscillator Modulation switch to. You may now be able to hear the sound of the Oscillator 1 modulated by OSC 3. Use the MOD DEPTH knob, and/or the Modulation wheel of your keyboard to increase the effect. If the Filter Modulation switch is ON, listen to the effect of modulation on the filter. The Modulation Sensitivity curve can be chosen from hard, medium, or soft (the default), using the SysEx commands shown later in this manual.
SPECIAL MODES
The A-440 switch can be used to set the MODEL D into various modes of operation. This is done by turning the A-440 switch on and off a certain number of times within the first 5 seconds of turning on power to the MODEL D. The number of times determines the mode, as shown in the table below. The Power LED will show the current value by flashing.
MULTI-TRIGGERING
Multi-triggering – On: playing a new note will change the pitch and also trigger the filter and loudness contour envelopes.
Multi-triggering – Off (default, Legato): playing a new note will change the pitch, but with no new triggering unless all notes are released. For example, you can play a note and hold it down, and any new note will play and use the envelopes of the note being held. The second note will often play after the attack and decay time of the held note has passed, so the second note will not have the sound that the attack and decay usually give.
NOTE PRIORITY
Note Priority – if more than one note is played at the same time, this sets which note has priority: the last note played, the lowest (default), or the highest.
POLY CHAIN
Poly Chain – if you have multiple MODEL D units, you can connect them in a Poly Chain 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. Each MODEL D must have the same MIDI channel number set using the rear panel switches. Only set the Poly Chain ON for the first MODEL D. Turn it OFF when you are done.
EURORACK
The MODEL D synthesizer can be taken out of its factory chassis and fitted into a standard Eurorack case (not supplied). Please see the details shown later in this manual.
FIRMWARE UPDATE
Please check our website, behringer.com, regularly for any updates to the firmware of your MODEL D synthesizer. The firmware file can be downloaded and stored on your computer, and then used to update the MODEL D. It comes with detailed instructions on the update procedure.
MODEL D System Exclusive Commands
Some parameters in the MODEL D synthesizer can be changed using MIDI system exclusive (SysEx) commands. A MIDI utility such as the popular MIDI OX can be used to send the SysEx command data string to the MODEL D using the USB MIDI connection between the host computer and the MODEL D.
SysEx Data Format
The following data format is used when creating a SysEx message (with the data beginning with F0 and ending with F7).
F0 00 20 32 aa bb cc dd ee ff F7
The various items in this SysEx data string are described below:
Command Table
*Note: If you use SysEx instead of the recommended A-440 method to turn on the Poly Chain, then the Poly Chain Device ID of other units in the chain is not set automatically. 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 tID=3 ID=3 and so on. All MODEL D units must have the same MIDI channel.
Retriggering Style
These examples show the difference between the old and new retriggering styles.
Poly Chain Style
These two tables show the difference between the old and new poly chain style.
TABLE OF NOTE RESPONSE- Old poly chain style
TABLE OF NOTE RESPONSE- New poly chain style
Note: Turning on the Poly Chain will affect the note priority function
Command Examples
Note: All command parameters should be in hexadecimal format.
Note: A decimal to hex conversion table is shown below. If you are using the MIDI Transpose command, then the 3rd column shows the MIDI IN Transpose that corresponds to each data value. For example, if you wanted a transpose of +8 as shown in the table above, then the data sent is 14 (hex).
Eurorack Installation
The MODEL D synthesizer can be removed from its factory chassis and installed into a standard Eurorack chassis (not supplied). The module width is 70HP. We recommend that this procedure be undertaken only by experienced service technicians to prevent personal injury or damage to the unit. The Eurorack case will need its 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 VDC power supply connection to be made. A 10-pin to 16-pin adapter ribbon cable is supplied to connect to your power supply.
Warning: Before proceeding, make sure that your power supply is capable of supplying +12 VDC, 1 Amp.
Warning: Make sure that the connections using the supplied adapter cable supply the ground and power to the correct pins of X23.
Procedure
Follow all steps in the order in which they are presented.
- Disconnect the power cord and all other connections to the MODEL D.
- Undo the 8 screws on the top panel as shown. There is no need to undo any other screws.
- Disconnect the two cables from the lower side of the main PCB of the MODEL D, and remove the assembly from the chassis.
- Store the chassis assembly and the power supply adaptor in a dry, safe place.
- Securely connect the 10-pin end P1 of the supplied adapter cable to connector X23 on the Main PCB of the MODEL D.
- Make sure your power supply is turned off and disconnected from the AC mains.
- Make sure that your power supply will supply the following to the pins of connector X23, as shown in the diagram above:
- Securely connect the 16-pin end P2 of the supplied adapter cable to your power supply, and double check all connections are correct.
- Securely install the MODEL D Synthesizer into your Eurorack, using 8 screws in the front panel.
- Perform a full test and safety test before using the MODEL D.
- The 3.5 mm MAIN OUT connector on the top panel is used instead of the ¼” rear output, which is no longer present.
Setting the MIDI Channel
Once installed in a Eurorack, the MIDI channel number is automatically set to channel 1 (as the MIDI switches are no longer present). 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):
- Disable the MIDI Channel Switches by sending the appropriate SysEx command.
- Change the MIDI Channel by sending the appropriate SysEx command.
