Changing the driver mode usually won't help.

In Sonar, if the synth is properly set up, you can hear the notes as you click the mouse on the musical staff. I have never used this method in BB/RB since I work exclusively with audio in these programs. Attempting to play a melody with a mouse in real time is a huge challenge that most people are not capable of doing well.

I have used this method for writing both musical parts and drum parts in years past and even in a fully capable DAW like Sonar, this can not be done successfully using a mouse to play in real time. The timing of the notes will not even be close to accurate. The only option is to set the DAW to loop over a several measure section, and use the mouse to add and edit the notes. Each time it loops, adjust the notes with the mouse until you have the part correct. Stop and start playback as needed in this process.

The best way I know that allows you to hear the notes as you are writing them in real time is to have the DAW in record mode and be using a MUSICAL KEYBOARD sending the notes in as midi as the project is playing. Essentially, you are playing along with the music playback and the notes you play are being recorded as midi.
