If that is true it would be good news indeep for S1 and PT, but it don't work that way in Reaper. To be clear what exactly are you playing. 1) Synch the plugin to the DAW and then run from DAW transport, or 2) Turn off the the plugin synch and play from the plugin transport? Do the both follow the DAW's tempo map?? or just one of them? or are you saying something else?
