Swami does real time generator control on a per voice basis (rather than
a MIDI channel). This requires that voice pointers are kept track of
which is easy in this case because instruments are being loaded by Swami
rather than FluidSynth. This is probably isn't convenient for your
situation though. The sample loop start/end offsets do work in that
situation, in real time. I don't see it making much sense in the case of
setting them for an entire channel, unless they are offsets (which might
actually be the case).  Still it would seem like one would want to
change the loop points for an individual voice, rather than all voices
playing on a MIDI channel. Cheers.
