Developing a midi interface for Elektor Formant

Elektor Formant Midi Interface (6)

I am currently working on a midi interface for the Elektor Formant. Of course it is possible to use any midi to CV interface since it is a modular synthesizer, but I wanted to add some features only possible with a custom interface. With this interface it is even possible to have 3 voice polyphony !!!

Features so far:

  • 4 individual CV outs. 2×12 bit high precision, 2×8 bit
  • Glide and master pitch controls
  • FM input
  • CVs are controllable by midi notes or controller messages
  • Leds for CVs and Gate
  • Switch between standard kexboard and midi interface

Planned features:

  • Analog gates
  • auto glide (switch glide on and off)
  • nice front panel

This is the prototype PCB:

I am going to sell PCBs (much nicer ones than the one on the left of course) as kits if there is enough interest in the interface…so drop me a message
