hello ingo and others-
could you describe to me in more detail than is available on the
doepfer webpage what the differences, advantages and disadvantages
would be between the two different bbd ics

i prefer a longer delay time, as i would use a slapback and or
reverb/delay effect more than i would use chorus.

your sound files were helpful, thank you.
