If I had to come up with a partner 120hp row to permanently sit on the Matriarch it would look something like this. These modules tend to get the most mileage with the synth.

Awesome, thanks for that response....I happen to just order a Matriarch case for mine from Erik Needham Woodworks....it will have three rows of 150 HP....2 x 3U and 1 x 1U....I'll have the Zorx Electronics 1U CV Bus and Bus Expander...as well as their 1U Through module which does what that Back 2 Front module does...I considered adding the ST Modular Toolbox 1U to fill in that 1U row.

Definitely looking at Batumi and considered Triple Sloths (and maybe another cool NLC module).

Any thoughts on what might be a good sequencer to throw in there? I was considering Metropolix

Also considered (if I could find one) a Sinfonion...maybe overkill for using with the Matriarch?
