Functions

func WriteGMProgram

func WriteGMProgram(wr midi.Writer, ch, prog uint8) error

WriteGMProgram is a shortcut to write GM bank select control change message followed by a program change.

func WriteReset

func WriteReset(wr midi.Writer, ch, prog uint8) error

WriteReset writes a kind of somewhat homegrown GM/GS reset message. The idea is inspired by http://www.artandscienceofsound.com/article/standardmidifiles. The following messages will be written to the writer on the given channel:

     cc bank select 0
	 program change prog
	 cc all controllers off
	 cc volume 100
	 cc expression 127
	 cc hold pedal 0
	 cc pan position 64
