Finally got the Tonic engine in my Gin drum synth tweaked fully and happy with it all. It took ages to get right 
.
@popcorp, I’m going to open a PR for a new drum synth plugin adaptor as the current one only covers the sample based engine.
Anyway, here’s Gin v1.0.0 - A synth drum engine based on the PO-32 Tonic. Each key has an A + B side and the blue encoder morphs between these.
The main params are directly editable using the encoders and a shift+encoder setup. Then as the Tonic engine is SOOOO deep I’ve included advanced editing screens behind T1. You can then page through these to modify all 21 params in the engine.
Just going through motions now to push live on GitHub and create .op1p file, etc. Any custom firmware creators want to pull this into their FWs please be my guest. MIT licenced and based on Eric Lewis’ libpo32.
