Open a Toontrack MIDI clip, with the Toontrack Drum Map. I'm not at my DAW, so this may have the wrong terminology, but the process should help. I still use the native drum synth when looking for the right loop, but then can drag it into the alternate MIDI map to have it play properly in the other synth (AD midi in SD, or SD midi in AD). I've done it for my go-to SD kit, and also to use my SD MIDI files in AD. You'll need to do this as they use different mappings for the kit pieces.
It's not hard to create a drum map to use Toontrack MIDI files in AD (or vice versa).
