http://www.seventhstring.demon.co.uk/xscribe/ I found out about this software after looking for comments on the Tascam CD-BT1 Bass Trainer. All I can say is that its GREAT I'm just using it to slow songs down, and loop particular sections of songs. I spent a while working with YYZ at half speed to figure out Geddy's unison runs and solo's and its very affective. I still haven't figured out how to use the Stereo Mix or EQ controls to make the bass easier to hear. I'm having a hard time with the final run at the end of the song (in unison with Neil)If anyone has any tips, let me know But I definately reccomend this software for practicing and learning any song that you wish was a bit slower.
