Though the BR-600 is by no means new, I am new to it. I have the manual, but when they say the machine is intuitive, I'm just not sure to whom. On my ancient Tascam 4track cassette recorder, when there was a song in a key too high for me to sing, I could just slow down the tape and when I played back at normal speed, I would hear the vocal in the higher pitch. Even though it's (hopefully) in the manual how to do this similar thing on the 600, I have yet to find it. If you know, or possibly it might be similar in a different model, please share. Anecdotal fixes always beat manual mining. Thanks.
