Here I have published a video (with no voice) where I show how I made the percussion with Geonkick synthesizer in my last published track, i.e. how it works in real life. I don’t know why YouTube lowered the sound too much, increase the volume and choose HD settings. The next version of Geonkick I am working now will be 1.6 where I’ll add envelopes for filters.
I have saved the presets and I’ll commit in the repo in folder examples, develop branch and will be published in v1.6.
