This is entirely speculatory, but surely a slow multiplex in itself =
isn=E2=80=99t going to cause that kind of instability? That would =
probably sound more like a delayed and jumpy reaction to the input.

It seems to me much more like a blocking callback function. It takes a =
certain amount of processing time to deal with each instance of an =
input, and it isn=E2=80=99t triggering the samples while its still =
dealing with that input.

If this is the case, and Roland can=E2=80=99t simply use a non-blocking =
callback pattern or make the callbacks more efficient, then it may =
result in the input being stored in a buffer and acted upon when there =
is time to deal with it, which would mean less responsive controls but a =
jitterless solid clock.
