Thanks for the input! Really appreciate the Zadar tip, I wasn't aware of that module at all. I swapped out the Dual EG for that one + expander. I went ahead and swapped the Dixie with an Erica PicoDSP and a Befaco out3, for a couple of reasons.
You were absolutely right that I wanted to get an audio processor in there. But I also realized earlier today that the Cre8 case sums it's input 1+2 to a mono output, and I thought it might be worth my time to consider what the case might look like with a stereo output module.
So this version includes that, and the picoDSP to give some reverb and delay where there were none before. All within the form factor and exactly 10 power connections. I might consider just living with mono output from the case and try to fit another 4hp module in there instead. Not sure. Thanks again for your suggestions.
