Detailed Description

An Abstract implementation of MidiDriver for Simple Low Level support of Midi playback

Note:: An implementation of LowLevelMidiDriver needs to implement the open(), close() and send() functions. Implementing increaseThreadPriority() is optional, however it is strongly recommended that it is implemented. If it's not implemented, the main Pentagram thread MAY use too much CPU time and cause timing problems. Similar, implemeting yield() is a good idea too.
