LOL,, excellent,,, Well I got it working!!!! all it took was to restart Bandhelper for some reason and bang!
In the attached Snapshot for example the Preset changes to Setlist 4 - Preset 4 (1D) Below that, the CC setting controls which snapshot on that preset ...so here i have selected preset 1D which Snapshot 3.....
The only snag is when I change song it only triggers the Program Change, not the CC, if i hit the midi button on bandhelper it then triggers the CC change and changes the snapshot.... I am sure there is some tweaking to fix that . I am sure i saw a setting in Bandhelper that asks what order you want tp send Midi : Program Changes; CC's....
But delighted to at least have the one thing working! Its going to reduce my toe tapping between songs immensely.
