I’ve got a snapshot which was working fine with stable zynthian in January, but with current stable the audio plugins are not wired in correctly, their inputs are connected to capture instead of their respective zynaddsubfx parts.
Here is the snapshot json audio_routing converted to yaml:
audio_routing: Dragonfly_Plate_Reverb-00: - ZynDistortion-00 Open_Big_Muff-00: - system:playback_1 - system:playback_2 ZynDistortion-00: - system:playback_1 - system:playback_2 zynaddsubfx:part0/: - Open_Big_Muff-00 zynaddsubfx:part1/: - system:playback_1 - system:playback_2 zynaddsubfx:part2/: - Dragonfly_Plate_Reverb-00
So it should be:
- part0->big muff->playback
Here is a patchage screenshot which shows all the audio plugin inputs connected to capture1/2
