I'm not sure about this approach. Reverbs are the very last thing I'd have a
large amount of due to the processing involved. If at all possible I'd
always try to deal with the issue by setting volume and mix. Clearly this
isn't always a option for all reverbs; we may want to throw acoustic
viability to the wind and instead deal with reverb as a per-voice parameter
for a "purely synthetic" aesthetic.
It's a interesting issue; LiSa doesn't allow for per-voice outputs, nor do I
think the ChucK architecture offers any options for that type of
functionality; at least to my knowledge.
I'm not sure I understand the problem as the original post and code don't
really go into what exactly Andrew is trying to do, making it hard to
determine what the problem is, especially as I don't have a computer with a
SMS (that would have to be a Mac in this context, I think) at hand.
I would think that any behaviour we care to define here should be available
using one reverb and two instances of LiSa, on fed directly to the DAC and
and one fed exclusivley to the reverb (which would end up at the DAC as
well, of course), combined with LiSa.voiceGain(). Thanks to the build in
reverbs being linear and time invariant we could safely use the two
instances of LISa in paralel, in identical ways except that one would set
the amount of straight signal for this voice, with the other setting the
reverb level with no difference in the final result from using many reverbs
I think that would deal with what I think the question is about but I may be
I'm not sure, BTW, why the SMS is polled in this way and not using "hi =>
now;", is there something speciffic about the SMS that is different from
other HID devices that makes this preferable or is there some other reason
to go for this method? I can see a possible need for a constant poll rate
but I think that in practice data will still be quantised according to the
buffer size? I may well be missing the reason for this due to not having
such a computer here, just curious.
Hope that helps,
