Start small, you might hate it.
Modular is fun…ish but it’s annoying as well.
the “sound” as you said isn’t that much of a gap (if at all). And the fact you have digital effects and oscillators makes it even less of an argument. Sound isn’t a valid reason to get a modular system since 2005. The workflow, the controls, the weirdness… these are valid reasons.
the absence of preset and the need to rebuild the basic blocks every time is really annoying… It is fun on the spot, but getting stuffs done with modular requires a hell lot of discipline
patching is fun… and not fun at all at the same time. It’s playful, a lot of happy accidents happen. But when a patch doesn’t make a sound because you plugged one of the bazillion cables in the wrong hole (or one is faulty)… you can easily waste hours following aaaaaall the signal paths for one stupid mistake.
It. Is. Really. FUCKING. Expensive. I mean… you can have a full fledge analog synth for the price of a single module (for real: you can get a Dave Smith Tetra (half a prophet 8) on the used market for the price of your average boutique dual oscillator module).
So, I’d say, grab a Mother 32 and a dreadbox Erebus 3, or a 0-coast or a Pittsburg semi modular. They will remove the hassle of the “basic patching” (VCO to VCA to Filter…) while providing all the fun of the modular world. If you get em used, the resale value will stay the same, so no risk.
Try it for a while. Make songs with modular. See if it’s your jist or not…
Don’t get a loan for a complete modular system… just don’t. You might resell it all in a couple of months and lose tons of money.
I insist: You may very well REALLY not like it (there’s a reason why people were happy to throw it all through the window in the 80s and 90s : it IS a hassle and digital IS way more convenient).
IF and only IF you like it and your awake your inner Alessendro Cortini, grab ONE module at a time, get them used (so you can sell them if you don’t like them without losing money), learn each module, ONE AT A TIME. Buy stuffs when you face limitations you can’t find a workaround for, otherwise you’ll be overwhelmed pretty fast, buy duplicates and underuse everything.
