As I mentioned in the introduction, I am planning to build a Kosmo format module around the Teensy 4.1. My interest is to combine the power and affordability of digital synths with analogue synths.
For now, there are some draft schematics. Maybe anyone would like to have a look
The module has a rather generic interface with
- 8 CV inputs
- 8 control knobs
- A TFT screen (with card reader)
- A rotary encoder with push button for menus
- Stereo audio out
- Stereo audio in
- DIN MIDI input
- USB for programming and MIDI input on the front
- Possibly a USB host interface
- I may add some more push buttons or switches later on
This allows, for example, multi-operator FM synthesis or up to 8 harmonics additive synthesis etc., where each operator can be CV controlled in one parameter. I imagine also emulations of Braids/Plaits etc. are possible.
Besides the hardware part, I plan to implement some software interface for the whole thing. Like this, anyone can easily start playing around with the module.
My choice of components was driven by making it cheap : Everything is available on Tayda, except for the Teensy, the Teensy Audio board, the display and the rotary encoder. The project is totally untested and I only have the schematics. I will order the components from Tayda and then hopefully test this out soonish, hoping that nothing will blow up
