The @koma_elektronik and @passepartoutduo Chromaplane Synthesizer is not played with a keyboard but with two electro magnetic pickups.
Like a doctor with a stethoscope you are hunting for the ten oscillators on the board. You can even mix in an external signal and play it with the pickup. In this example an arpeggio from the OP-1 is added in to the electric sounds of the instrument. No external effects used, just the filter and the delay on it.
When I first played this in 2022 I loved it and promised I would support its release. Happy to say it is out on Kickstarter now, at a very fair price. Congrats to Koma and the duo for making this! #synthesizer #kickstarter
