Hi Dan,

apparently the LiSa buffer is still a single channel but you can pan the
LiSa voices between the 8 output channels.

The reason LiSa is so slow may be that in its tick-function (invoked at
sample rate for every LiSa in the graph), there are some loops over the
8 output channels and 200 (possible) voices even if it doesn't play or
record or only one voice is used. Should have nothing to do with
unnecessary function/method calls since they are inlined. Will have a
look soon how to optimize that.
Would seem plausible to me that only a requested number of voices is
actually used and there should be a dynamic number of output channels
(one for each voice). I don't think the latter is currently possible in
If nothing works I think I'll just patch it for my setup to use a single
output channel and only one voice.
