VST Macro Controls allow you to control VST plugin parameters in a more advanced way than Live's Effects Rack device.
Unlike the Effects Rack which displays parameter values in a range from 0 to 127, VST Macro Controls displays the real values of VST plugin parameters. It is also possible to configure the controls as knobs or buttons, and the knobs can be configured in bipolar mode.
The device acts on VST plugins loaded in Live. This prevents VST plugin latency misreporting issues that can occur when wrapping VST plugins inside a Max for Live device, and also does not interfere with automation. So projects can be opened in versions of Live that don't have Max for Live.
