Bought the kit from smashTV with pcb and all component parts, plus the stm32 control pcb and an stm32 unit. Haven't gotten around to building and likely won't anytime soon so looking to sell this to someone looking to build a seqv4. Basically everything you need for the build minus a case. Also have a Seqv4 Lite I'd sell with a faceplate (acrylic I made) but no case - fully working. I've got a midi i/o doubler for that as well.
Seqv4 Kit + stm32 pcb and stm32 unit - $200 shipped priority anywhere US.
Seqv4 Lite - built - $115
Midi i/o doubler for it - $35 (also already built)
Everything listed above - $325 shipped US
