Reverse Reverb

[chrisk]

Not sure about reverb, but there is a Reverse Delay patch:

Fantastic Patches: User-Creations

Selection 4: Reverse Delay by @Hymnosiac Time for an effect! Get backwards! Unlike most delays, this patch applies a unique pattern to the playback of the delay. Instead of playing reversed audio at a constant interval, this effect randomly plays panned fragments of incoming sound in reverse. Use the different presets to move through additional harmonizations. Download: https://patchstorage.com/reverse-delay/
