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.
