Andrea:

Thanks a lot for the explanation. I understand that the multi-tracking is all done with software only. All my attempts in recording songs were done playing everything live. That obviously limits a lot the arrangement complexity and sophistication. I begin to realize that with multi-tracking, interesting results can be obtained if we are patient to capture all the voices present in an orchestration. At least your recent recordings sound much more professional and the musician is the same (good one!)
