The lack of LFO depth manipulation makes a lot of tricks much harder to do if not impossible - the CycEnv has to be used to do it, but the shape of this is limited compared to the Waveform LFOs when used as an LFO. LFO depth could also be controlled holding Shift + LFO rate.
Similarly, Tremolo and similar effects are impossible with this Synth. Obviously it's possible to access the VCA in the architecture since there's an option for velocity - it just needs to be. This would also help some of the issues I've had setting the Attack knob for some oscillators KapsrkyStrings - Double assigning it would potentially make it smoother.
You could also make it so it's possible to Overdrive it somewhat by increasing the VCA, which would help a lot.
