I'm running Studio One 3 on the latest iMac and have the StudioLive CS18 and RM32 connected via a Motu AVB switch. When putting in effects on Studio One it already has presets to control any stock plug-ins via the CS18 and UCNET. However I can't figure out how to assign buttons for any third party plug-ins, or change the current presets for any of the stock plug-ins. Any help is much appreciated, thanks.
