Hmmm, I guess you could maybe wire up an A-138-e quad three-way crossfader module to get SEM-style crossfading between filter modes for all three A-127 filters. The fourth crossfader could probably be modified to sum all three filters with a level control (or be left as-is to do a three-way crossfade between the three filters).
 This would probably make most sense if you also add separate inputs for the filters.
 Ahh, a new project for when I actually have some spare time ;-)
 Best,
 Denis
