Caustic Song file (optional):
In Modular, the crossover/splitter module inverts its high output for reasons known only to Rej and Jeebus.
Caustic's reverb does not remove the dry signal, even at full wetness.
Adding an inverted signal is like subtracting that signal from whatever it's mixed with
-Create a dry signal
-Run it through a modular, and a crossover/splitter
-Then apply reverb to the inverted signal
-Let both signals play with equal volume in the mixer
--wet only reverb
In practice I would mix the signals in another modular so volume isn't a pain to manage, or resample altogether.
Try other effects, it's really fun.
If this was incoherent it's because I'm sick. I do not apologize.
