I went through and read what you like to hear from your electronic elements.
Research "sample & hold" modules. Bleeps and bloops often sound pretty good with random/semi-random pitches.
Quantizer. If you want generative pitches, forcing them into a scale is a bit more musical. That's what a quantizer does.
Research Euclidean rhythms. There are a few modules with this capability (I love the Temps Utile for this). Combining them, using a logic module, triggering one one set of Eucs with the output of another pattern... you can go on and on. It makes coming up with interesting patterns pretty easy without a lot of composition.
Effects. Reverb, delay, ring modulation... etc. The standard lot. External (non-Eurorack) effects are cost effective. But Eurorack modules with CV inputs offer more creative possibilities.
You have two semi-modular synths in your rack. All of your basics are covered.
As your Eurorack collection grows, you'll probably evict both of them from the rack to make space for more modules.
Bonus points for leaving open rack space for expansion. Feel free to look up my rack "The Machine That Goes Ping" for any of the stuff I use.
