[sdiy] six-trak POS

[Barry Klein]

Thanks, John - I'll try that tonite.  I was using my pc to monitor the midi
and to dump sysex patches to it.  Never tried controlling it I think.

The version of fw is v11.  The sn is over 999.  I may try the earlier fw for
the heck of it - maybe someone put an older pcb in it(?)

Have you used the diag rom?  Is it supposed to play anything with that?
Weird that the stuck Program led goes off with that code.  And the
button/led test works, and the system memory checksum test works... 

Barry

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..
