Transposing by itself is half the picture with music. Hand position and fingering is the other half.

I assume you play something.

Take a tune and play it in G. Then play it in Bb. The actual chord changes are the same just taken up a minor third BUT are you using the same hand and finger positions, the same chord inversions? Now take it down to D. How about now? Same chord inversions and hand positions?

Probably not which is why simply taking an RT and transposing it won't always sound good because it's not how a real player would do it in that key. Your whole playing technique can change when you transpose something. This is another reason why a pro RT is recorded three or even four times to account for that. It's not just to help with audio artifacts.
