hello anton, 500 ms delays on a bbd-module would greatly decrease the frequency range of the audio signal. even the biggest bbd-based delays cannot output frequencies greater than 1 khz with a delay time of 500 ms. so digital delays are much better for such tasks. best wishes ingo --- In Doepfer_a100@yahoogroups.com, "Anton Coops" <dubshot@x...> wrote: > > Hi all, > > Before there were plans for several bbd-modules, but it sounds like > there will be only one big fat extremely cool 'universal' bbd module > now?
