multilooper by Expert Sleepers
For AL version: 2.0.0 and above
This script is an example of how you can use the setOthersParameter() function to create a multi-plug-in looping system.
To use this as intended you will need to load four copies of Augustus Loop into your host app, and set the OSC Port on them to the values 1 to 4. Then configure your MIDI routing to send incoming MIDI to just one of the four.
An example skin is provided for use with this script - see here.
