Do you have an sound example that uses something like that?
I own a ADA STD1 which provides this for its mutlitap flanger, but I
never use it as it never sounds "round and rolling".

This is a wrong information. The JP6's hardware does not allow this. And
even if it would. This would be a monosynth with four different sounds
stacked - what for?

The only extension for vintage synth which allows this is the supermax
extension for the DX7.
