I read the GP comment and I was about to downvote. Then I read your comment and sat up in my chair.

I use Ableton and I also play with Logic, FL and the occasional tracker. I would love to know what you mean with "the vim of DAW" and perhaps if there is a video or text that describes it?

Great hotkeys for everything .. just install it and give it a try. '?' key is your friend - from this you will learn the ways of the REAPER ... ;)

For tutorials: you need to get some Kenny Gioia in your viewing time. It will make the power of REAPER so much more clear:

You just reminded me about Reascripts.

Now I know what I'm spending the rest of my lockdown doing.

If you're interested I have a load of scripts that access some command-line audio processing algorithms (non-negative matrix factorisation, harmonic percussive source separation) to do batch processing inside REAPER.

Thanks for thus - very cool bunch of scripts, highly useful!

Amazing. Cheers dude.
