ok! kind of hard to tell for anybody else but...
If you want new type of sounds you can try some mutable instrument modules, Rings is my favorite!
You can also add some more modulation sources for weird sounds and traditional ones. The Batumi is a dope quad LFO with multiple options but it's just an exemple.
What i really like for conventional "instruments like" sounds is voltage controlled ADSR so i can vary one parameter with a random source and the decay with the keyboard tracking while triggering a short white noise with the "end of release". all that give a "alive" feeling to my sounds.
I also see you don't have sequencers or quantizers which are really usefull even if you play your sequences from computer or external "main" sequencer
