Windows only.
Made by Gianluca Elia for Daniel Sousa. Based on schollz/osckeylogger (and that's why it's in Go).
Sends alphanumeric keypresses (that is, a to z, 0 to 9 only) to Ableton even when Ableton is not in the foreground.
Ok, first you need to install git and go. Then:
git clone https://github.com/elgiano/abletonAlwaysHotKeys
cd abletonAlwaysHotKeys
go install -v
abletonAlwaysHotKeys
or, from the abletonAlwaysHotKeys folder
go run main.go
