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

> [@Fantastic Patches: User-Creations](https://forum.critterandguitari.com/t/fantastic-patches-user-creations/3918/5):
>
> 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/](https://patchstorage.com/reverse-delay/)

For reverse reverb, you can make it with a regular reverb, with a fairly large reverb setting, I think Freeverb will work great for this. And then add an envelope after the reverb, triggered by an envelope follower.

For actually triggering the envelope, you use the envelope follower with a threshold. When the signal fed to the envelope follower is higher than the threshold, it will trigger the envelope and fade in the reverb.

So you need:

- Freeverb
- An attack/decay envelope
- An envelope follower

There’s currently 63 reverb rooms i am looking for some cool new ones  
If you have an IR file of a reverse room you can add it to the IR folder
