In this tutorial you will learn how to use the DP Meter Pro plugin (DPMP)'s real time capabilities in Ableton Live: use it to let any instrument influence the parameters of any effect for any other instrument. This tutorial shows these capabilities with Blue Cat's free effect.
Note: if you are on Mac, you have to use the VST version, because Live does not support MIDI output for Audio Units nor VST3.
Step By Step
01 - insert the DPMP on the source track (select the track and drag and drop the plug-in):
02 - Select the DPMP preset settings in the main menu (right click on the background):
