Maybe I misunderstand, but if you are patching the VCO outs directly into the delay, you probably won't get much -- just some weird phasing effect mostly. Sounds like what you are getting.
Put the an amp envelope between the VCO and the delay and see what happens. The VCA out of the M32 will probably do the trick.

OMG thank you so much! Spent over 12 months not patching this right and wondering why I could never get delay to sound right! Now I've nailed it with the correct patching lol
