(maybe) found bugs on effect manipulation

disclaimer: could be me doing something wrong… anyway,
Adding an effect to a synth layer, actually i’m not able to hear it affecting sound.

  1. if i choose an effect as layer itself, by now i’m confused about why assign him a midi channel (maybe for controls?), anyway if i press “audio routing” inside bold select layer, zynthian (UI at least) freezes.

P.S.: all this happens on this encoderless zynthian with rpi4 and just usb soundcard (behringer). With full hardware zynthian (V1Kit) everything seems to work fine.

On Genuine Zynthian the issue on standalone effect layer actually happens, but without freezing UI, just “system” checkbox in audio routing section is turned off and refuses to be activated, resulting in no chance to assign it
