hi floppy, the more stages, the poorer the sound quality - in objective terms, anyway. so you'll get a much smoother (=less grainy) flange effect from a bbd with few stages. when it comes to delays, you can radically reduce the clock time of these modules to produce long delays, even with fewer stages, but the trade-off here is that you have to filter out the highpitched whine of the clock itself, giving you a sometimes drastically filtered delay. with more stages, you can set the clock higher for any given delay time, and so the filter can also be set higher. less quality, more high frequency content. the maximum time with 4096 stages is unusable in the sense of being an echo - all you get is a few clicks a long time later, so bad is the quality :) so it would be interesting to hear from other users how that pans out with the other bbd versions. however, we're talking here about very long delays. for all your favourite robodub effects, lots of stages = good. i assume the longer delays are less suitable for karplus-strong experiments, but again, others will be able to comment better on that. and while we're discussing bbd's, has anyone found any good use for all those phase switches at the bottom? stu
