I don't know for the Mooger Fooger. The Blacet is a BBD based device.

As already mentioned. A basic CV-control is possible for all technical
types of delay. The real problems start, if you want to "play" a delay
with a relation like 1V/Oct (doubling the delaytime with 1 Volt) with a
range over several octaves. I don't know for sure, but I think the Time
Machine is not V/Oct. To have a useful range you also have to have very
short minimal delaytimes. For example the Blacet Time Machine has 10 ms
as minimal value. This means the highest(!!) possible note with Karplus
Strong or tube resonating synthesis is 100hz. Imagine a VCO, that does
not play higher than a f' ...

I do not know literature in english.

I think this something which is very complex and will be out of the
range of doepfers development possibilities. I think this is a range of
products, wher we should accept, that the all-digital world is much
better. I have Sony D7 Delay for stuff like this. It is heaven and hell!
