DIY - FOR EXPERIENCED BUILDERS - PCBs ONLY
Use this module to connect a range of popular USB MIDI keyboards:
and directly play your analog modular synthesizer. Polyphonic and monophonic operation.
Build it yourself - FOR EXPERIENCED SOLDERERS ONLY - This is a set of 2 high quality PCBs and an optional front panel ONLY for users who want to purchase their own components and build their own module. Some product photos above show COMPLETED build. You can add a pre-programmed PIC microprocessor to the order if you do not have the facilities to do this yourself.
• 8 outputs supported which can drive 8 synth voices
• Command mode enables various functions to be performed using the keys
• POLYPHONIC PLAYING MODE - play 8 notes polyphonic using up to 8 synth voices
• MONOPHONIC PLAYING MODE - the device will play monophonically with the same note playing on all 8 outputs
• Various split-keyboard modes allowing you to group the outputs for better control of key shifting
The module (when using our front panel) is Eurorack size and only 8HP wide leaving room in your rack for other modules. With the PCBs only, you can wire any pots and jacks to your own front panel or standalone case.
If you are a composer, create your own MIDI sequences, backing tracks or songs using your favorite MIDI-USB keyboard.
The module uses a PIC 24 bit microprocessor to convert the midi messages from the keybaord into digital codes which are then converted into gate and control voltages for 8 voices with precision DACs. These are buffered with precision op amps providing precise tracking over three octaves and to within 0.01V over 5 octaves.
The following MIDI-USB Keyboards are supported, others may work also.
Comprehensive documentation, parts lists and firmware are provided in the documentation link for building, testing and using the module.
Hold down the SHIFT key and turn ENCODER 1 counter clockwise a couple of rotations in order to set the master volume to 0. Once the master volume is set to zero, press the OCT (-) button 5 times and then Midi-CV-8 will be in command mode.

PMFoundations supplies a range of DIY electronics for the modular analog synthesizer enthusiast and musician.
My objective is to provide DIY solutions that are better than average and comparable in sound quality and functionality to commercial pre-built units. I don't think the DIY community should be left behind and treated as if they have second rate equipment.
I spend a lot of time trying to get the bugs out. I'm not saying there is not room for continuous improvement.
