Jim, you're my toughest critic and I understand your point of view.
The modular world has captivated me while I try not to let my passion get out of hand. On the long run that could be a dilemma.
Yes, the next logical step would be a bigger case. Even though my small system may seem ridiculous to most of the community, I'm pretty happy with it for now. Combined with my Subsequent 37 I can get a lot of movement and noise out of it.
Anyway I would like to replace the 903a with another module, preferably a second synth voice. Does anyone have a suggestion?
