It works and sounds painfully awful but I couldn't not do it.
I tried using C version of #Orca with SunVox as always, but apparently there are no snd-seq kernel module in #Droidian, so no midi, sadly, and I was not successful in running Jack too, to use it with folderkit which recieves osc.
So I ended up using uxn Orca with it's built-in synth.
@vacuumbeef Hmm sounds like something's not aligned right with audio callbacks
@mcc yeah probably
