Ah, I see. So the RTR function requires a press after the release. And you don't want a press--you want to go directly onto the multiple press function. I think you are right--I don;t see a way around that. The only work around I can think of off hand would be to have the release the the bimanual responses on consecutive trials. For the RTR component, you could use a style with 0-1! as the minmax value. That would cause (I think) DirectRT to continue automatically to the next trial after the key release. Use a short trial interval like 50ms and just account for that when calculating your RTs. Does that make sense?
