Detailed Description

Base class for all kinds of polyphonic instruments, provides somewhat reasonable voice management, pedal support - and little else. It's implemented as a base class with virtual functions, so there's some performance loss, but it shouldn't be horrible.

Todo

it would make sense to support all notes off controller too
