I donāt have the OT in front of my right now to try it out and say for certain, but I think this is the way I would go about creating such an effect. I would set up a flex track with the dark reverb in the second slot. You could place a recorder trig on this flex track, so the track is constantly sampling from either a thru track or from the inputs directly. You could also set this recorder trig as a one-shot trig so it only samples a new clip when you arm the track.
If you set the reverb time to max, it will repeat infinitely. This will probably get out of control if the sample keeps repeating and the verb keeps building, so you could assign a trigless trig to lock the mix on the reverb, or assign a scene to the mix parameter. The delay would perhaps be more ideal for this job, because you can p-lock both the mix and the send controls. If you set a filter before the delay and set the delay time to be short, Iād imagine you could get some very nice freeze-like effects. Another bonus of using the delay is you could use the delay control mode to chop up the time of the repeats, which would probably be really interesting.
A super cool benefit to using a flex track for this is that you can trig the sample chromatically, so if you want an octave up freeze effect, you can do that by setting the pitch parameter, or you could have two scenes where one turns the mix up on its own, and another changes the pitch and the mix.
I hope this helps! Play around with it, and even if it doesnāt perfectly recreate the freeze, in the least, it is the OT, so you know it will probably be awesome
