Cascading Delay + Cross Feedback
This combination gets rather interesting. The settings of
Delay Level and Feedback of Channel A and Channel B
will interact strongly, and it is all too easy to encounter
runaway feedback. For easy control from the front panel,
adjust Delay Feed of Channel B for the desired total
feedback. Alternatively, you can patch an external
attenuator between Send B and Return A.

You also can combine the previous patch's "cross-feedback" with
separate audio sources. In this figure, the final patch of the cross-
feed is ghosted to show that it may be a path of runaway feedback
if you're not careful. But with appropriate settings of the Delay
Feed and Feedback controls, this patch provides a very nice
range of rhythmic bouncing and spatial effects.
Feedback with External Processing
The classic use of Send and Return ports in a time delay
processor is to provide a "side-chain" for modifying the delayed
signal before it is returned to the input mix.
Probably the most classic application of this kind of side-chain
processing is a simple low-pass filter in the feedback path. This
causes succeeding repeats to soften, with less high-frequency
content on each pass. This is similar to the behavior of echoes
in an acoustic environment, and for this reason a low-pass filter
is included in the internal feedback path of many conventional
delay processors.
In patches involving externally processed feedback, the gain of
the processing chain is always a concern. It may be too little, or
it may be too much! In the case of filters in particular, the gain
may be suitable overall, but not at the frequencies you want to
recirculate. If the filter is resonant, runaway feedback may
occur even when the overall gain is low.
