Dick:

You shouldn't need to have ASIO to get what you're after.
Mine works fine with MME.

- Which version of BIAB are you using? (I'll assume 2014)
- I'll also assume that you can hear an existing song when you play it, and that, after you enter notes in Editable Notation, they will sound OK when you hit the play button

- Go to Opt > Midi/Audio driver set up
- Under "Midi Output Driver", see if you have a MS GS Wavetable and select that
- I also have enabled: Use VSTi/DXi Synth, Route MIDI thru to MIDI driver and have selected "VSTi/DXi Synth Setting (Coyote W/T)"

Let us know if you already set things up for ASIO and got it working.
Good luck!
