So my second rack of 6U is almost complete and I took advantage of Halloween sales to add a clock, sequential switch, delay/reverb FX module with Mimeophon, and two fun sound modules. Here is what I have planned:
As you can see it is not perfect and I use external sequencers and plan for a larger third case in the future to add a larger sequencer, matrix mixer and more logic and support modules. But I think that with Kinks/Links, Hex VCA with attenuators/inverters and the Doepfer Sequential switch and Pamela New Workout for clocking, I have most things covered for a smaller setup.
