Aha...remembered another one: SYNTHETIC MUSIC SYSTEMS, from the UK, started about 2001. These guys made patchables...but these patchables were assembled in sort of a modular method to build up a sizable system, all 100% rackmountable. I thought this was actually pretty snazzy some years back, but they also went in a different direction to what was coming down the pike at the time, and that probably contributed to their disappearance. Here's a site that looks back at 'em: https://www.cykong.com/Synths/SMS%20MARS+BOB/SMS-MARS+BOB.htm
