How to reset and modify the current microtuning

As soon as you re-enter SNM (by pressing the sus pedal or sending a value greater than 64 via the

CC you have assigned for this task), the current detuning of all the notes will be cancelled and the

Microtuning display in the instrument GUI will be reset to zero:

Keeping the pedal pressed, you can immediately detune a new set of notes by pressing the

appropriate key switches (see 2. above).

This allows you to create selective microtunings as you work.

Applying microtuning through SysEx

It's possible to control Microtuning through MIDI SysEx messages. SWAM responds to two

protocols: Custom protocol and Yamaha PSR A3000 arranger protocol

Custom Protocol

This protocol allows to change both Microtuning and Transposition on the fly through SysEx

messages.

1) Microtuning message

Each message is 4 bytes:

1st byte: Begining of the sysex (F0)

2nd byte: Note value (00=C, 02=C#, 04=D, ..., 12=A, 14=A#, 16=B)

3rd byte: Detuning value (00 = 0, 4E = -50)

4th byte: end of sysex (F7)

F0 10 10 F7: reset all notes to not detuned

Examples:

F0 00 4E F7: Note C = -50 cents

F0 10 4E F7: Note G# = -50 cents

F0 16 00 F7: Note B = 0 cents
