perfect! that worked.
now...

that is more or less the generic heavy render part, i just changed the NI audio parts you told me and write to some variables in the midi section to use in the lv2host long thread. while trying to just put an "if" around the rest and running these lines:
gBcf.push(BelaContextFifo::kToLong, context);
/// receive from the "long" render
const InternalBelaContext* rctx = (InternalBelaContext*)gBcf.pop(BelaContextFifo::kToShort);
if(rctx) {
BelaContextSplitter::contextCopyData(rctx, (InternalBelaContext*)context);
}
in the corresponding else, i realised two things:
the midi part is still communicating with heavy of course, so i still adjust parameters in my heavy patch, so i will rewrite the midi-part into the else section as well, so as to mute midi to heavy as well when switching
my approach to just put an if around everything else does not work :-) (didn't think so, but one can try) the audio is simply muted in my case. so audio input and output need to stay in the chain i guess. which part do i need to leave in the above render if i just want audio in from the regular (short) render to be passed to the long render and audio out from the long render back to the short one?
sorry if this is all obvious, and thanks as always. i feel i am getting closer to my desired result.
