I think I've come up with a better tile row configuration:
ModularGrid Rack
Lots of changes. First up, there's a 4-channel CV expander for the Temps Utile next to the...well, Temps Utile. The expander gives you four CV inputs to control the six channel sequencer which does...

"7 modes, selectable per channel:
- trigger sequencer/sequence editor
- clock division/multiplication
- LFSR
- random w/ threshold
- euclidian
- logic (AND, OR, XOR, NAND, NOR, XNOR)
- burst
- DAC (channel #4 only): random, binary, "Turing", logistic, sequencer/arpeggiator"

...which is a helluva lot more than the Steppy! Kicked that shiznit right OPEN! Then I swapped the Duatt for the triple attenuverter by Transient...same architecture, but MORE. ADSR EG is still there, swapped out the Mosaic VCA with Intellijel's, and then the Mosaic stereo out.

The addition of the T_u really opens up the timing and sequencing capabilities. Implement this row plan, and the build's game gets upped significantly.

Soooo... unfortunately I bought a lot of stuff last night (and already had orders for maths and a couple others). My owned list has updated because some of the stuff I had previously ordered was out of stock and I made some changes. Also, a few of the modules you mentioned I couldn't find at any of the sites I have been shopping at which means I'll need to import them.

Some additional info... I plan to use my Elektron Analog Four to fill in some gaps (CV sequencing, gate, clock) while I build this thing. I also have CV capabilities with my OP-Z.

Heres the current list. I wish there was a way to say what I owned vs whats in flux on MG.

Maths (I know its big but I already ordered it and I built my case so if I need to make a bigger one in the future so be it), Disting, Row Power, Dual Linear VCA, Forbidden Planet, Surface, Duatt, Line output. Everything outside the skiff is currently out of stock and I was unable to order it. Feel free to make comments on those as well. I appreciate the help.
