OSCTouch - Change song part

I have a question if anybody knows how to change the song part using OSCTouch or trigger midi event change. Thank you

The OSC Implementation chart for GP3 is available from the support page or you can use this direct link to download it.

To switch to the first, second or third part respectively of a song, you would send the OSC messages

/SelectSongPart 0

/SelectSongPart 1

/SelectSongPart 2

Note that the first part of a song is indexed at 0

Thank you very much
