ryan,

what's up thanks again for those mods, they got me started on this beast.
aha, the firmware binaries. this is definitely a worthy cause!
kingconga, are you still interested i could send you all the 707
sound roms and the firmware chip (postage paid both ways) if you can
post the binaries. let me know.

now, shall we start a discussion about requested features let's see:

-midi out in write mode
-pattern select in write mode (while running)
-negative shuffle/flam
-swap patterns between drum sounds (kick plays hh pattern, etc -
overkill )
-some type of auto-fill that sends divided clock frequencies to the
selected sound

exciting,
greg
