\brief STK tabla drum class.
|
|
|
|
This class implements a drum sampling
|
|
synthesizer using WvIn objects and one-pole
|
|
filters. The drum rawwave files are sampled
|
|
at 22050 Hz, but will be appropriately
|
|
interpolated for other sample rates. You can
|
|
specify the maximum polyphony (maximum number
|
|
of simultaneous voices) in Drummer.h.
|
|
|
|
by Perry R. Cook and Gary P. Scavone, 1995 - 2004.
