I started up my gear as usual today to start sequencing, and found
that my Polaris was triggering in Mono mode only...after numerous
tests and filtering, I've hit a wall.

To sum it up, here is the minimal setup I scaled down to to try and
find the bug, 1 Oxygen 8 midi control keyboard going out to a Motu
Micro Express, which in turn runs out to the Polaris. I thought
perhaps SOMEHOW the Polaris was recieveing a Mono Mode ON command, but
it is indeed NOT. I got so far as to filter every single midi message
out that was going to the Polaris except for Note On, and it still
automatically goes into some sort of mono mode. The wierder bit is
that if I play the Polaris' local keys, it plays in full beautiful
polyphony, but as soon as I trigger it externally it goes right into
this mono mode, even from it's local keys after that. I can't get it
back to polyphonic without resetting it, and then once I externally
trigger it again, it's back to Mono. WTF?!

If anyone has ANY ideas or suggestions PLEASE let me know...the
Polaris is THE polyphonic cornerstone of my setup (along with an ATC-1
for my mono cornerstone), without it I'm up shits creek for a long
long time due to utter lack of financial support....and it figures
this happens when I'm right in the middle of recording a final demo album!

Thanks,
Byron
