Listen feature fails until midi note on keyboard is pressed

When i hover over a chord and press the mouse button to listen, the chord will play for a few seconds and then will no longer play until i physically press a key on my Akai mpk keyboard which seems to free the program up but then the exact same thing just keeps happening. In other words I can play the chord for 3 or 4 seconds with my mouse and then it drops out until I hit a key on my keyboard which seems to reset it.
