@glia, if you haven’t already you should give the beta firmware a spin, it’s great! It allows you to turn the 6 env outs into 1V/oct outputs.
Here’s Dan’s description from muffs, and a link to the firmware:
The way it works is that flipping the Fast | Slow switch to “Fast” turns the 6 ENV OUT jacks into 1V/oct outputs for each channel. Morphing does not have any effect, it just jumps from one note to next. For now, each one is tuned to the nearest semi-tone.

Also, they are starting work on an oscillator alt-firmware in October…
