So i got this of a subreddit and I found it to be quite nice for creating a shimmer reverb with the OT:
T8 set to master, length 128. T1 for your source sound (sample or thru), T2 flex machine with recording buffer R2 assigned. R2 is recording SCR3 set to T8. Place 64 trigs and 64 recording trigs on T2 and set playback pitch to +0.2 (you can also play with other values edit: I think a real shimmer pitch-shift the reverb tail + one octave but I found that to be a too big step on each trig). Dark reverb on T2, 100% wet mix and long reverb time. Set HP, LP and track level to taste. Credits to user “Lakehousememory”
