class ZXUtils::AYMusic::MusicControl

The main music control structure.

The most important is the music_control.counter word entry which can be used to synchronize music with some external code.

Other useful entries to watch are:

• music_control.ay_registers: a mirror of AY-3-891x registers (0 to 13).

• music_control.chan_a.current_note: a currently played note index (0..95) on channel A

• music_control.chan_b.current_note: a currently played note index (0..95) on channel B

• music_control.chan_c.current_note: a currently played note index (0..95) on channel C

• music_control.chan_a.volume_envelope.current_value: a current volume level (0..255) on channel A

• music_control.chan_b.volume_envelope.current_value: a current volume level (0..255) on channel B

• music_control.chan_c.volume_envelope.current_value: a current volume level (0..255) on channel C

• music_control.noise_envelope.current_value: a current noise pitch (0..255)

• music_control.chan_a.chord_progress.counter: == 0 - no chord on channel A, <> 0 chord active on channel A

• music_control.chan_a.chord_progress.current_offs: if chord is active, half-tone delta of currently played note (0..31) on channel A

• music_control.chan_b.chord_progress.counter: == 0 - no chord on channel B, <> 0 chord active on channel B

• music_control.chan_b.chord_progress.current_offs: if chord is active, half-tone delta of currently played note (0..31) on channel B

• music_control.chan_c.chord_progress.counter: == 0 - no chord on channel C, <> 0 chord active on channel C

• music_control.chan_c.chord_progress.current_offs: if chord is active, half-tone delta of currently played note (0..31) on channel C
