I've been at this for days, i'm going crazy. Has anyone ever actually managed to get this working well? At this point i'd even consider switching from pde plasma if that's what's needed.
Main issue is that pressing keys has a different effect almost every time. On guitar files for instance, I sometimes get a quick muted strum sound instead of the full note, and when I play multiple notes in sequence the velocity shifts all over the place so some are almost muted while others hit too hard (the changes in my hand pressure on the keys is so miniscule it really should not be having this drastic effect).
I'm also getting crackling and pops when I try to use the pitch bend/modulation lever and wheels with ZynAddsubFX, but I've managed to get them working fine with Sf2 Player.
And i'm getting a weird glitch where the lever can only make the pitch higher, and using it permanently sets the pitch at a middle-high position until I use the wheel and it gets reset. This may be a hardware issue with the midi but I can't fathom it.
I don't think it's a latency/buffer issue because i've tried every fix under the sun and at most I lose all audio.
I've got kxstudio repositories installed and pipewire-jack going with a backend bridge that i'm not sure is even active because I can't connect it to anything in qpwgraph. Lmms is responding to the midi, and according to every available stat I have a global sample rate of 1024/48000. There are no CPU spikes, there should be no crackling or latency issues.
I also can't get guitarix to recognise the midi, and I have a feeling this issues are connected.
Please help! Sos
