I’m very curious if users can share successful experiences with delaying cv signals with « audio delay modules ».

I suspect that looking for one module to do comb filtering and long and accurate delays will be challenging ?

Synthesis technology E102 is a very fun module.
Joranalogue step 8 implements accurate track and hold (and is a super fun module too)
For comb and such, Joranalogue Delay 1 is impressive.
