Hello All: I was listening to one of my favorite CDs by Mani Nag (thank you Lars and Peter) and wishing that I could play. . .practice. . .fumble along with it (his sitar is tuned up to D) I decided to record the CD onto my Mac (which BTW is equipt with a CD burner) and, using Bias Peak Pro mastering software, transposed it to C, which is where my Mangla is at right now. If anyone is interested in having this done to any of their favorite recordings, for study purposes, email me at qehqeh@yahoo.com. No $ involved. - K.K.
