Great stuff guys; thank you!
As I'm getting further in to this, I'm realizing I seem to skew towards the 'instrument-per-case' side of things. My 6U case is more or less my hybrid version of a Make Noise Cartesian system meets modified CV System, but I'm very seriously considering taking the Pressure Points, Rene, and Wogglebug out, and putting them in a controller skiff, and then adding a couple Meng Qi controller pieces, and a few other bits and bobs. I'd use the Make Noise 3U skiff for that.
My 4U/104 Intellijel is mostly Mannequins and Ansible at the moment, and I need more space RIGHT NOW, as I've got other modules sitting on a desk. They are sad.
I guess I'm wondering if I'll get annoyed at having all these different cases floating around, none of which can be attached together, like the 4ms cases, or the IJ 4Us once the joiners come out. So I'm on the fence: another IJ 4U, or 7U?
One additional albeit small benefit of the 7U case is that it moves a couple minor functions out of racked space altogether. The MIDI ports (assuming you need them) and audio I/O jacks are on the chassis, so it frees up a few hp more in the 1U space.
I'm really keen to see what other 1U modules IJ offers. Some mods would be nice, and especially a fully featured VCA. The Quadratt is so invaluable though. They've promised a headphone out, which would be great.
Once the new -isms comes out, I'd like to migrate my Mannequins/Monome setup there. But I'm not sure it'll be big enough, as I have dual JFs and will have dual Mangroves, and eventually a TT and ES on top of an Ansible. We'll see how it specs out.
