I experimented making a wrapper/container for VST/AU MIDI Effects plugins using Max For Live. This time I have Scaler with TATAT VST2 inside their containers, triggering notes to Repro-5, all in the same track. Read the results of this experiment and download the wrapper if you want to test it: https://audioswiftapp.com/midi-effect...
DISCLAIMER: This is an experiment I did for myself and I share this information if you want to try it on your own. Be aware I can't offer support if something goes wrong on your side. I recommend to open a new Live set, and tests this device or the ones you make in many different ways before using them in important projects. Third party plugins behave differently between developers, and depending if you choose VST, VST3 or AU formats, the settings will be saved or not after closing the project, or in my experience, they could even crash Live. It’s very important you fully test the devices.
