Yep, this is definitely the case. I have an A-188 and I've invested in two other BBD chips specifically for this reason. I have an MN3206 (128 stage) for K-S physmo stuff, a BL3207 (1024 stage) for chorus and more lofi K-S stuff and a MN3205 (4096 stage) for discrete delays. The chips fit into a socket so they can be easily switched.suthnear wrote:In fact, even chorus is tricky because in order to get the 20-40ms delay times conventionally used for chorus there is too much clock noise in the signal as the oscillator used to set the bbd's rate moves down into the audible frequency range.
The thing about the doepfer BBD is it's quirky. It doesn't have an expansion/compression circuit to help the s/n ratio and there is no LPF after the delay to get rid of clock noise the way most typical BBD based stompboxes do. It does however give you full access to the feedback path and a CV out that follows the clock speed so that you can improvise such things. It will not track 1v/oct, even over a single octave so getting it track anything like a chromatic scale is an effort in futility (even using something like Silent Way or Volta to calibrate). When you get to low clock speeds (longer delay times), even if you have filtered out clock noise and such, the delays get very gritty.
All that being said, it's one of my favorite modules. Follow it with a low-pass gate and you can get some of the nicest plucked string sounds. I'd just say that if you are used to software combs like the ones in Zebra and the Tuned delays in MFM2, the doepfer BBD is a much different beast. The analogue systems rs290 is probably better for getting those kind of results.
I've been following Bazille with MFM2 in the signal chain a lot lately. Using pitched noise as an exciter. I've gotten excellent results that way.

I didn't pick up on the sarcasm. No offense was intended.
