Thread: Not sure what to call this
To add to what Jim mentioned, I would really recommend revisiting what kind of gear bands like Tangerine Dream were working with. It was often very simple analog gear, at least in the early days. A few analog oscillators and filters (Moog, Roland, Arp, etc.), simple 8 step sequencers like the Doepfer or Behringer (though I would recommend the Winter Modular Eloquencer for your purposes), dotted eight note delay, etc.
I would go back to the drawing board on your plan. You can likely achieve what you want to do in a much less expensive manner.
As a follow-up question, what gear do you already have?
