No it’s actually really intuitive, esp. as a sound source. You don’t need to ‘understand’ the internal relationships to have fun. I just got a second one. For me 2 out of 3 of the sound-generating RUN modes can also just be twiddled away on without really ‘understanding’ them.
In sound mode, at its simplist:
Intone: spread between tones relative to identity, which stays fixed.
Time: master tuning of identity.
Ramp & Curve: shapes waves like the pictographs show.
FM: FM amount if you patch something into that input.
Mix out: to hear all outputs mixed together if you aren’t able to / don’t want to mix the other outputs externally / separately.
Much more worthwhile & rewarding jump into the format than a boring old generic oscillator or whatever.
edit: as far as your self-described temperament goes, just don’t be seduced into hooking it up to a Teletype and you should be fine
