Changing to and from alternate tuning on the Variax Acoustic 700:
I have my VA7 on my Helix floor through the Variax jack. I’ve learned that I can change the guitar to and from the alternate tuning by sending a sysex command to the Helix.
This sequence:
F0 00 01 0C 07 01 5E 01 F7
changes from normal tuning (green LED) to alternate tuning (whatever is saved to the instrument) (red LED).
This sequence:
F0 00 01 0C 07 01 5E 00 F7
changes from alternate tuning (red LED) to normal tuning (green LED).
The change is irrespective of model selected.
This can be used to switch to altered tuning (or whatever alteration you have saved in the red position for the given model) from apps like Song One, OnSong, and various DAWs and others that can send sysex to MIDI. Thus it can be used programmatically if needed. Channel is not used for sysex, so you don’t need to specify that.
