Re: [xl7] CCs output on reset

2006-12-30 by Aaron Eppolito

Hitting stop three times resends all data at tick 0.  This info is
typically only played the first time through the sequence, not at ecery
loop.  (this is why the event editor doesn't let you get to the first
tick).

More background: cc79 and cc80 are arp status and send bus select if I
recall correctly.  The XL-7 stores this per track so that it sets those
settings up for each pattern.

And finally, the solution.  Either don't save the sequence with data on
a track assigned internally that will eventually go external, or, if
you have already, remove the offending cc data on your external tracks.
 It's easiest to do this with the erase events menu (where you could
target cc79).
