Hi Montxo,

Band-in-a-Box will only output audio to one stereo output, sorry. You can't separate the tracks like that.

This would work though: If you have a hardware sound module (synthesizer) like an old Sound Canvas, select that as your MIDI Output Driver and uncheck "Use VSTi/DXi Synth" so all MIDI (including the metronome) plays through the sound module, and use a RealTrack for the bass. Now the bass will play through your soundcard since it's audio, and the metronome will play through the synth since it's MIDI.

Send the output of your soundcard to your speakers so you can hear the bass, and plug the drummer's headphones into the sound module.

Thanks
