I saved some backing tracks from Band In A Box as wave files (44100, 16bit) and planned to use Sonar X2 Producer to record a melody and improv track. The importing went okay and I recorded a test melody track on Soprano sax using a Zoom H4N (also set for 44100, 16bit) as my input audio interface/mic. Everything was fine. I was using a Presonus Studio 26c as the output audio interface to some external speakers. I then decided I wanted to switch to a different horn and use some Logitech headphones to confinethe playback sound while I was recording.
NOTE: When I first imported the audio tracks, I put markers at key points in the song. Everything was fine: the markers lined up with the playback and no latency was in evidence.
After switching the configuration, two mystifying things happened:
1) the markers are still in the right place (I can see by breaks in the audio) but the time to the beginning of the playback of the backing tracks has doubled.
2) when I re-record the melody (a) it starts late on playback: i.e. it isn't aligned with the backing tracks, and (b) it plays back an octave low and at half speed.
