This post reminded me that I have a Slim Phatty that would love to be CV controlled… so that’s what I’ve been doing all night.
Since I already have a Minitaur and Slim Phatty, I think the only real draw to the Sirin (for me) would be the slick AU/VST interface with more range in the oscillators. The SP has the higher range but no AU/VST control (not entirely true, its just 3rd party, costs $$$ and to my knowledge, is no longer updated/supported).
This appears to be a pretty compact, reasonably priced, desktop analog synth. The AU/VST really opens it up but then you also get the CV control and upper registers that the Minitaur stops short of. Very cool. Despite appearances, I’m really trying to talk myself out of it.
