Okay, now that you've got a Werkstatt, a Mother-32, and a Grandmother - stop buying synths for a while. You now have a formidable arsenal of monosynths that you should explore before you fall into an expensive habit. Honestly, if you can return the Werkstatt, do it. I wasn't going to talk shit on your fun first synth purchase, but it's a wee little baby, and now you've got grown up options. Use the money to get some outboard f/x - a used Hall of Fame reverb pedal is cheap and hugely rewarding, sonically, and since you're doing analog stuff, maybe get an inexpensive analog delay pedal. I realize the Grandmother has a spring reverb, but that's also a very specific type of reverb - and doesn't do anything for your Mother32.
Just... practice your instruments for a little while. You've got *great* instruments.
