I am rather new to the forums but not BIAB-don't flame me yet. I recently downloaded a trial version of REAPER. Drop and drags are simple enough. But when I choose open a midi file, I get the correct track imformation on screen and the cursor moves when play is pressed. However, no sound is heard. What should I search for to correct this. I work witin the confines of a lap top. Nothing external except an Allen&Heath ZED10 FX mixer. BIAB and REAPER use MME. Thanks in advance ELC
