Available as an assembled Module and as a DIY project.
This Module is currently available.
Waveshaper with 4 CV inputs
The build is great for beginners learning how to surface mount solder. All the passives are 0603 and there is only 1 IC with a pretty wide pitch.
To adjust the trim pots, input a saw wave. Measure the voltage of the signal going in to a channel and adjust the corresponding channel's trim pot so the output has the same voltage.
There is also a XWSX exapnder module in the make
