FWIW: I defined 4 stomp-buttons to switch :
1 : cc7 - 0 , cc8 - 0 --> minor
2 : cc7 - 127 , cc8 - 0 --> minor 7th
3 : cc7 - 0 , cc8 - 127 --> major
4 : cc7 - 127 cc8 - 127 --> major 7th
External 7 attached to cc7, External 8 attached to cc8
As a note: in Axe-edit, the shift amount on Voice 1, synth 2 does not show correctly
Is should be 3 instead of 16 wich shows in Axe-edit (at least on my PC)
