First, here's what I'm using: Yamaha MG16 mixer, Delta 44 sound card, Shure SM57 mic in Channel 1. Acoustica Mixcraft 5 mixing program or Audacity 1.2.6. Now the problem. I have to record a soloist, harmonica player, playing with the music of a backing track. The finished recording should give me a track of the backing track and a track of the soloist. This will enable me to edit the sound levels of both. They are then saved as an MP3 file. For setup I load the backing track in Channel 1. With Audacity I click Record, a new channel opens up recording the original backing track. If I try to setup a seperate channel for the soloist and start recording both the backing file and the soloist are on the same track. The same thing happens with Acoustica Mixcraft 5. The backing file and soloist end up on the same track. I need them seperate so the sound levels can be editied then the both tracks saved into one MP3 file. This can be uploaded and made into a CD. How do I get the tracks to be seperate?
