Need fx pedal schemes, esp flangers

This is because of the conversion method used. The BBD is essentially a "flash"
converter.. where the speed of the digitals is limited by the A/D conversion
time... or in the case of Delta Modulation by the speed of the integrator and
comparator (not to mention memory...) Late model DeltaLabs had 8:1 ratio... with
todays devices probably any desired sweep range could be used if you throw money
at it...

Most people will buy the cheap box with the processor  / memory instead of a
dedicated delay line... (I will)
Sorry... the BBD is already as cheap as it gets...

If you want a really dramatic flange without super high sweep rate... delay the
dry signal by about .5mS and sum it with the variable sweep at 50/50% ratio...
this will give complete cancellation at the top... through zero flanging....
