Here’s a super fun JS plugin by Geraint Luff called JS: Droplets ☔️
This effect replays the notes of a chord randomly. It also has a wide range of parameters that can be adjusted to create many variations!
🎥 Here’s a demo of how it works
You can control the retriggering rate, and how much this is affected by velocity or the number of current notes ("Independence").
You can also allow it to transpose the input up/down octaves, to move it to a target note range. This (like everything else) is automatable, so your music can float up and down in pitch.

How to install
You can install this via Reapack by importing the following repository:
To import them, go to REAPER > Options > Show REAPER resource path… and place the plugins inside the Effects folder. Restart REAPER afterwards.
