ok i think usually i am not the person who talks first and then thinks, even if my entry on this board might make it seem like that.
i think it's a k-rate/cycle sync issue, not a midi issue after all.
my test setup is this: i have two axolotis running the same simple patch with a square oscillator and a s-rate VCA. OSC is reset and VCA is triggered on a midi note gate signal. both are being fed the same midi input. while i was not expecting both osc's to be in sync because the clock cycles will be offset and not synced, i did expect the offset to be consistent.
but hitting random midi notes, every now and then i get a different (constant) amp offset bewtween both axo's. this is probably due to those notes falling into a moment where one axo is already on the "next" k-rate cycle. which would also explain that the offset difference between both options constantly is around 1/3ms.
1. AXO 1 "normal" as in more likely
2. AXO 2 "normal" as in more likely
3. AXO 1 with extra offset
4. AXO 2 with extra offset
so yeah. am i drawing the right conclusions? how do i get high speed / custom baud midi input, and pass it to my OSC/VCA reset inlet in s-rate?
edit: from what i can tell both the VCA trigger and the OSC reset are offset by the same amount. so that part is in sync at least haha.
