The #1 failure mechanism on the Moog modular are the rotary switches. Also, having these switches in kits present many problems with proper wiring. The MOTM-300 attempts to eliminate all potential sources of drift. The cermet pots just do a better job than discrete resistors (not taking anything away from Larry's Octave Switcher Stooge module). If you are switching octaves, the FINE tuning must also be 1 octave of you have the potential of "dead zones" where you just can't tune to a certain pitch. > > 2) Semi-tone range of the fine-tune control. 11 > semi-tones??

Being an 'assembled' person, unfortunately > they were not an option. The FINE tuning is set on the '300 by a 3.32M resistor. I can change this to a 4.7M if you request it. This will "tighten up" the spread by 3.32/4.7 or 30% (say from 11 to 8 semitones). Paul S.
