Hi zs,

With every respect for your opinion, I'd just like mention that while transposing is very easy to achieve with midi because midi is simply alpha-numeric data (it doesn't involve actual sounds - they come later when a synth interprets the midi data), Realtracks are audio and this restricts what can be accomplished with them.

I don't know if you have ever tried adjusting the pitch of an audio file in a DAW but once the pitch changes more than one to two semitones, audio artifacts become very noticeable and interfere significantly with the quality of the sound. You can easily test this in Realband by creating a Realtrack track and then changing its pitch a third (say).

With Realtracks, the artists have recorded a number of patterns in different keys. When a user enters chords into BIAB, the program identifies which of these patterns are appropriate to the key signature being used. This means that the audio files are not pitch-shifted more than their audio integrity allows them to be shifted. That's why when a song has it's key changed and is regenerated, the Realtrack patterns often sound slightly different from what was being played before.

When a chord that's a 3rd higher is entered into BIAB, the program will regenerate the whole song. It doesn't simply modify the notes in the bar that had the chord changed.

It is not a bug that midi transposes and Realtracks do not. It is simply that the two different types of sound creation require different techniques to make them work effectively.

Kind regards,
Noel
