I hope it is OK to advertise this here. I made a small app/plugin that plays live drum loops and that may be controlled using a single midi CC, like arrangers of old or the BeatBuddy pedal. I wanted to get a bit into audio programming and it’s my first time on an audio project so I’ll take any feedback/constructive criticism on this Hopefully I did not do too many blunders, although I do take the callback lock sometimes…

You need rhythm description files and sfz banks (or an external sound generator, which is mostly what I use until I improve the sfz part beyond sfzero…). Some description files are included in the repository. It works fine on my raspberry setup too if that’s your thing.
