Macro is a mappable knob for automating parameters across your Ableton Live set.
This was quite simple to make and I'm sure many people have made their own versions. And, a lot of the code in this device is taken from the Ableton Live Envelope Follower device. Still, I find this super useful and it's a feature I've been wanting in Ableton for a while. I hope that it is useful to you!
