Hi Arrrrrr,
Welcome to modular synthesizers! :-)
Well... everything is possible, there are members here who take a rack and put them just full with only VCAs because the motto here on this forum is: "You never can have enough VCAs"... now that's kind a of a practical joke, so just ignore that ;-)
You can take a rack like your above rack or a rack with just 5 oscillators and nothing else, everything is possible...
The big question here is... does it make sense? On top of that you have to ask yourself, what do you want to do with that rack? If you like to share with us what you like to do with your rack (what are your expectations?), then it becomes significant easier to check if something makes sense :-)
Anyway, having all that said. Regarding your above rack, assuming you have nothing else, just planning for that above rack, my comments:
- More than enough modulators for a relatively small rack, could consider perhaps a bit less
- You could consider to get a bigger rack (one more row at least; for what you are all planning to do here)
- Keep at least then one row of that bigger rack free for (near) future usage, don't buy everything in one go, start small, gain experience, adjust your planning/assumptions, buy a few more modules, gain more experience, etcetera
- I do see enough "fancy looking modules" (some call them sexy looking modules ;-) ) so you might want to consider to start with a few less of those
- And start with a few more classical components, for example:
- You could do with at least one more "normal" oscillator to start with, that Snazzy FX thing, is most probably nice (I got the Kick_Me module, nice module!) but it's not a "normal" oscillator as such
- Get also a more "normal" or more default filter, consider a WASP filter for example (Doepfer - A-124) or SEM filter (Doepfer - A-106-5) both good filters. If you want a bit more fancy stuff consider the Erica Synths - Black Dual VCF, though being a bit more fancy, still a bit of a classical filter too
- I don't see any VCAs, right? (you need VCAs, that practical joke about you never can have enough VCAs still has to make a point)
- Instead of that Erica Synths - Link, you might want to consider an audio interface module instead, depending on what exactly you are planning to do with it (some members here think/practice to live without an audio interface, that's up to them. I want to have a more worry-less-life and therefore I advocate to use an audio interface module; but at the end, it's totally up to you :-) )
- Other than the Maths you might want to go for one classic ADSR; at least consider it
Well I guess for starters that should help already a bit. Keep an eye on the classic build up of a synthesizer and look less towards those fancy looking modules, then you should be fine.
Have fun, good luck and kind regards, Garfield.
