Thank you Tina for getting back to me with great care and concern with some questions I had. She also had another Team Member (Jason) who got back to me in a timely manner with some confusion I had regarding Key Notes, Waveforms and Gridlines on a few songs. Your tips and advice was explained in great detail. I even did a little research on "algorithm" used for the analysis of key detection in which I better understand now. I greatly appreciate your time and efforts again. A company that provides excelIent customer service will keep a loyal customer forever!
