The class to play music using the MIDI device

Music program

Music program is recorded in the string array. In one array element is written a list of actions. Actions are written by a comma. At first a command, an equal sign and a command value are written. The following commands are available:

  • Tick - time in milliseconds through which all the commands of one array element will be performed. It defines the temp with which the play is performed.
  • Volume - the volume level, from 0 to 100.
  • VolumeL - the left channel volume level, from 0 to 100.
  • VolumeR - the right channel volume level, from 0 to 100.
  • Instrument - selection of the music instrument, from 0 to 127.
  • NoteDN - press a key. Number 60 corresponds to "do" note of the main octave, 61 - to "C sharp", 62 - to "re", etc.
  • NoteUP - release a key. For several instruments you cannot use release a key, the sound fades away itself, and for some keys it is obligatory to press.

It is possible to take chords, for example, "NoteDN=57, NoteDN=60, NoteDN=64". A possible parallel play on several instruments, for example, "Instrument=1, NoteDN=60, Instrument=123, NoteDN=60". Different instruments' volume can not be changed, all is played on the same volume, but you can change the volume of different parts of playing, for example:
