#3 BPM, Pan & Gain support

[suzuki toshiya]

Here is my scratch Pan & Gain support,
including BPM slider patch.
Possibly you can use it for demo purpose,
although there are a few problems I should fix.

1) Am I understanding Pan & Gain correctly?
See buffer.cpp.
2) In slow BPM (<80), there is too many clicking noise.
Wave calculation for slow BPM should be refined.
3) For Base Drum module, tuning gain & pan changes
its sound. Why?
4) Refreshing Pan & Gain slider should be improved,
I have to study more signals.
