Weird, and I see the irksomeness in this. Might do my head in, might not.
I don't know the UDOs and have no idea what parts are analogue and what parts are digital, but in my analogue head, I see this as an LFO output slider rather than two VCO input sliders, which I'd dislike. OTOH a fully flexible output/input matrix too makes one crazy (or me at least), so ...
BTW, from hazy memory, every synth I've used has had its quirks - analogue and digital alike - and I recently bought a Sledge for the nth time despite all the known stuff, as I just like it.
(Of course, it will almost never allow me to even enter sample mode. 😄)
