Hi Spencer-

Yes. If in the current release the dac/adc indexes are increased by 1, everything works fine, even the 1-2 connection.

I compiled and ran the recent SVN and it seems to crash at the end of a shred with a bus error. This didn't happen with the March 23rd version. I understand it's the SVN, and there are no guarantees that the code there isn't broken. ;-)

Thanks, Charles
