REAPER includes about 40 JS MIDI plug-ins that can be placed in the FX chain of any of your MIDI tracks or MIDI items. The basic steps involved in inserting and using Track FX are covered in the section Track FX Basics. If you are unfamiliar with these steps, you should review that section before proceeding. If you display the Add FX window and type midi into the filter list box (as shown above), you will see a list of those Midi FX that are currently available. Below are listed just a few examples.
MIDI CC LFO Generator
A LFO Controlled CC generator.
MIDI Duplicate Note Filter
Blocks duplicate notes.
MIDI Map To Key
A MIDI key mapping utility.
MIDI Snap To Key
This is a good cheat for bad pianists.
MIDI Router/Transpose
Routes events from one channel to another
MIDI Tool and MIDI Tool II
These do interesting and fun things to MIDI note events.
MIDI Transpose Notes

MIDI Velocity Variation Generator

MIDI Velocity Control

MIDI Pitch Wheel LFO

These plug-ins can be made even more powerful by the use of automation envelopes, which can be applied to any of their parameters. How to create, manage and apply automation envelopes will be covered in Chapter 18.
