Ah...now, if the idea of that uFold is to treat the two VCOs, you might be better off trying to jam a Tiptop Fold Processor in there instead. That module gives you dual inputs, and you also get a square-wave frequency divider for Roland monosynth-ish suboctaves. And even though it's 12 hp, it comes in at a lower price than the uFold. The circuit is a tad different, but the results from the Tiptop folder should be more or less the same...provided you only use one input, that is; the ability to unity-mix and waveshape, though, that's a definite plus and puts Tiptop's module into a different level of functionality.
