I’ve posted links to this thread in quite a few others recently but it’s been SO useful for me in controlling GAS.
My core kit is OT & Rytm. This leaves 2 OT inputs to add whatever I want, and means I don’t need a mixer, FX boxes, compressor etc (use OT master track). Up to now that’s been Virus Ti, this weekend I switched up to a 303 and DSI Tetra. I’ve got at least half a dozen other things I could plug in so there are a lot of combos.
But everything starts on OT & Rytm. As a result I’m learning those better (I couldn’t say I know them well yet), plus when I hear a sound I like I can sample it and let the OT do it’s magic. For me, ideal compromise between learning one box and the obsessive interest in synths.
