What more do you need! Everything starts dry until you bring the delay or reverb input level up via midi.
I have a patch setup especially for this job: Midi controlled reverb and delay delay time left, delay time right, delay feedback left, delay feedback right, delay input level and reverb input level. The reason my Quad has been such a major part of my music is the midi control 6 selectable realtime controllers based on which effects you have running in that patch.
The Quadraverb is a very flexible and controllable multi-effects unit with EQ, reverb, delay, resonator, flanger, phaser, ring modulation etc. Alesis Quadraverb 1988, MIDI, Digital Stereo Multi-Effects Unit
