Hi GuitarHacker,
I've followed your instructions, but when RealBand renders the song, it is all over the place (different instruments with different timing) and the audio (which I don't want or need) is a different tempo too.
I've never had that happen. The instruments are the same, timing should NOT change, and TEMPO should not change either.
The performance by the instruments may vary a bit but not appreciably. That is the nature of the real tracks used. If you take the same exact real track, and use it to make, lets say 3 or 4 supposedly identical tracks, you will notice that there are subtle differences in them. Lead tracks (solo) tend to vary more. I used this feature to comp 5 leads into one finished solo in a song.
If there is a huge difference between the BB version and RB version... to include the tempo and timing.... you need to investigate why. That should NOT be happening.
