Accessible Favorite FX Slot System for REAPER

Hi there,
I am Pradip from India. This is the first script I have written for Reaper.
This script will help you to add 10 of your favorite fx in virtual slots and easy to add the fx to your item or track using simple HotKey.

This system consists of two separate Lua scripts designed for fast and screen-reader-friendly FX management inside REAPER.

I strongly recommend you to listen/watch the demo of the script from this link.

1. Accessible FX Slot Manager

Accessible_FX_Slot_Manager.lua

• Assign FX to slots
• View slot contents
• Clear slots

2. Insert Favorite FX From Slot

Insert_Favorite_FX_From_Slot.lua

• Quickly insert FX
• Open FX window automatically
• Focus inserted FX

Requirements

• REAPER
• OSARA
• No reaImGui required
• No JS_ReaScriptAPI required

Installation

Extract the zip file and copy the folder called "PCS".
If you have an installed copy of Reaper, go to the following directory:

"C:\Users\Your User Name\AppData\Roaming\REAPER\Scripts"

Paste the folder "PCS" which you have copied before.

If you have a portable copy of Reaper, do the following:

1. Extract the zip file and copy the folder called "PCS".
2. Open your Reaper Directory and find the folder "Scripts".

FX Insertion Priority

Fx will be inserted in the last touched Item or Track. So, select the Item or Track before activating the script.
