In the ReaScript community, coders background is pretty diverse, so they all have their own specialties. And if anyone in the field has pushed audio analysis and maths stuffs to next level, it would be MPL for sure.
MPL is co-owner of the ReaTeam GitHub organization, which he initiated back in 2016 (note: cfillion and I are co-owners as well). His scripts are accessible for free (donations are very welcome!) via his own repository, already registered in Reapack. So if you have this extension installed, you probably have his scripts already!
Among these, there are some very fancy ones with complex GUI… Let’s see how far MPL pushed the game. 😎
Align Takes
Align Takes is a very advanced script to make two relatively similar takes timing match better, using stretch markers. The use case is loop recording or dual track recording, if you want to tighten up a bit the precision. This can works nicely with background vocals layers.
Learn Editor
Though I would recommend using ReaLearn for any MIDI Linking, it would be nice to have more controls on the native feature. That is why MPL made LearnEditor, which answer something really missing in REAPER out of the box.
Visual Mixer
If you are looking for a fancy way to mix your track, you can check MPL Visual Mixer script, a ReaScript version of Izotope Visual Mixer. Contrary to this VST, this one changed actual track properties, so it is really a GUI based track property controller, not an audio plugin. You can audio waveforms in it, which is quite high level of ReaScripting. IDDQDSound made a in-depth video tutorial about it recently.
Import Session Data
If you have ever wanted to import some other project tracks, but didn’t want to lose time by having to open it and wait for all the plugin to be loeaded just to make a simple copy paste, you can take a look at MPL Import Session Data script. Parsing .rpp project files is complex so this is definitely advanced as well!
RS5K Manager
REAPER come with a plugin called RS5000, which is a one sound sampler. It very good and has lots of feature to control the sample audio and mapping, while being extremely lightweight on CPU. But if you want to build a complete drum kit with it, you will have to have as lots of this plugin instances, and it quite become a bit unefficient to set up, compared to other samplers. That is where MPL RS5K Manager come into play, as a unified window to control all your RS5K instances and their parameters. Very handy!
As you can see, MPL made very advanced scripts, and all this using the minimal native ReaScript GUI engine, GFX, so it is quite impressive. Each of these scripts could have deserved their own post, and there are still more nice tools to showcase, but that will be for another time. You can see a list of MPL most advanced tools and ask for support on his dedicated Cockos forum thread, linked below.
Cheers! ✨
