The TL;DR case for a dedicated FREEZE switch:
- Short-Med GRAVITY no DELAY no FEEDBACK (normal reverb base tone)
- Tap FREEZE switch – capture a drone + dry signal overlay
- Short-Med INV GRAVITY no DELAY no FEEDBACK (inverse reverb base tone)
- Tap FREEZE switch – capture a fade-in + dry signal overlay
- Deep INV or GRAVITY medium DELAY medium FEEDBACK (‘verb within delay line base tone)
- Tap FREEZE switch – capture thick layers @ delay length + dry signal overlay
- XXX GRAVITY long DELAY high FEEDBACK (long decaying delay-‘verb)
- Tap FREEZE switch – capture a short phrase loop/’verb (-> 2 seconds) + dry signal overlay
- Short-medium-long FEEDBACK
- Tap FREEZE switch (in & out) – FEEDBACK level sets the fadeout time from FREEZE (sw) + dry signal overlay to base settings
- FEEDBACK = INF – For example, layer up complex chords from single notes.
- Tap FREEZE switch – Chord FREEZE background + dry signal overlay
- FEEDBACK = FREEZE
- Tap FREEZE switch – nothing. There’s no signal in the delay matrix to FREEZE.
- I see the FREEZE switch overriding any other value in the FEEDBACK / INF / FREEZE knob.
Now consider adjusting any / all of the combinations above with an expression pedal + FREEZE switch. And I haven’t touched on the resonant EQ and modulation variations. Or MIDI control. I doubt I covered it all.
The short case for a momentary / latching action built in to the ACTIVE switch:
- Take any of the scenarios above (and more). Momentary ACTIVE punches in the delay / ‘verb settings. A global BYPASS of DSP+FX should get the trails you’re looking for out of this. Other global BYPASS types will get you more of a gated, stutter effect. Momentary ACTIVE can dynamically ‘mix’ into whatever ‘verb and/or delay / loop you have set up.
