Sounds pretty good. On your harmonizer, did you use chordal or a scale mode ?? I always use scale mode and I need a unit that will let me program my own scales.
Hi Mirza
The harmony tracking is worked out using the backing track if you use the "Aux" input, if no "Aux" input is detected it will create harmonies from the background music using the onboard Microphone. It would also work by sending the headphone output from your keyboard to the "Aux" input.
You can also input the scale but it's something I never use.
This is the manual perhaps this could help with your query.
