Sorry, to jump in: a VC-delay with a wide range VCO, which is NOT exact
1V/oct, is useless. The wide range is required finally only for the
usage of the as a sound generator which uses a resonance/delay based
synthesis (Karplus Strong, Granular or similar). But what should be the
use of an Oscillator if it is not playable in clean 1V/Oct

Exact 1V/Oct is a MUST!

Very cool idea!
