I did a quick search and canāt seem to find anything about a grid 128 controlled eurorack switch matrix?
There are many posts about elaborate mixers, but I find there are already many mixers out there. There arenāt however (from what Iāve found) many musically controllable switch matrices. Theyāre also all huge. The WMD SSM is probably the most useful one (and compact to boot), esp w the expander. But it still only has 4x4.
I feel like somebody could very quickly put together a simple 8x8 (16 jacks total) switch matrix where every jack is routable to any another jack (or combination of jacks) - all of this being controlled by a grid. The control interfacing on the grid probably would need a bit of finessing, maybe some multi-colour LEDās on the actual module to denote connections (but probably not even necessary).
Then adding one more jack for cv control between presets routing scenes/ākeyframesā (similar to wmd ssm or mutables frames) would take it into super useful territory.
Maybe itās just me, but 4x4 isnāt quite enough but 8x8 could built enough interesting routing for a long extended diverse set (without extensive repatching). I canāt waste like 30+ hp on a these massive matrix modules if Iām trying to condense everything into a flight case.
Perhaps this canāt be done technically in a small space though.
Final note⦠it would be incredible if this could be done with op-amps and some sort of slew/morphing between routings heh but alas I get ahead of myself.
