Mixing the output from an external MIDI device
with the output from your BR-864 (Audio Sub Mix)
The Audio Sub Mix function allows you to mix the signal
input from LINE IN with the signal output to LINE OUT.
When performing synchronized playback using the BR-864
and an external MIDI device, you can use the Audio Sub Mix
function to mix the output from the external MIDI device
with that of the BR-864 internally, within the BR-864 so you
won’t need an external mixer.
Also, since you can output the signal from the MIDI device
without having to first record it to a track on the BR-864, you
can use the BR-864 tracks more effectively.
