Keep, was made as a companion to bastl instruments ‘kastle 1.5’ synth.
It’s a self-modulating modular analog synth based on the ancient XR 2206 IC, which you can still buy (in china) :)
I make limited numbers and offer a kit for sale. The kit is 50 Euro and built 86 Euro. Batteries not included :) See below for what is included.
This is a funk piece with the moat and keep playing together. It’s over the top but show what I made keep for :-)
Here is a complex example of self-sequencing :)
Open Sources includes several versions as fritzing files. The breadboard and schematic views are messy. Working on it.
The kit is pictured below.
What’s in the kit?
