I have installed Superior Drummer, but when I try to launch Toontrack Solo 64-bit it only shows EZDrummer. Superior Drummer is not listed so I cannot get to tge SD2 interface. I have already installed SL-Avatar library. on a USB Drive. Product Manager sees SD2 installed.I have used the drum icon on the toolbar to insert a New Drummer but it still does not show up. The attached screenshot only shows EZDrummer. Someone Please help.
