[sdiy] six-trak POS

[john tuffen]

Barry,
  Which version of the system software does the SixTrak have?? It's not in
'local off' mode or something silly? The non-responsiveness of the 'parameter'
button feels like that kind of a thing... Presumably you've tried looping a
MIDI cable between out and in? If it's in local-off mode, then that would at
least get the voices going...

Track-Record/select 7 will put it into local-on mode...

Cheers,

john..
