Beautiful, brilliant, go for it! Modules you have here that I use all the time and highly recommend: Pamela's Pro Workout, Disting EX, 3x MIA, Plaits clone, Rings clone, Maths, Clouds clone, O&C--excellent choices, all! I am not familiar with your other modules, but that is not a down-vote for them. I started out with a system smaller than this, and after 2-3 years had a system bigger than this. Any size modular synth is a blast. Enjoy it! I make mostly ambient music and organic noise.
Trim down this rack? I wouldn't. I would like to hear it!
