I need to have a RT guitar part lower in volume AND to be back to normal (from mute status) in the same bar. I cannot find away to do this, so I was wondering is it even possible?
Thanks
Yes. you can do this is Biab.
If you do attempt this, you should generate the RT and freezed it. Then export the frozen track as a WAV file. This gives you an exact duplicate of the RealTrack.
In your case, only two tracks are necessary. Import the saved WAV file into the Audio track. Be sure volume, panning and effects are the same for both tracks. They should be identical.
On the chord chart, split the measure into two, two beat cells.
Be sure when you import the WAV audio that the two tracks are synced. By splitting the measure, you can use F5 to mute track one in cell A of the measure on one track and use F5 to unmute the second track at Cell B of that measure.
Mute all other tracks except the two duplicates, Mute track one at the desired measure and the WAV audio on the second track to begin at the third beat of that measure. If you split the measure into two cells, each two beats, this would be beat one of the 2nd cell. Play the two tracks.
The result should be track one mutes for beat one and two. Track two will begin at beat three on another track and proceed. Track one remains muted so the track plays as if it's a from a single source. Since the audio is the same on both tracks, it will sound out that the original audio RealTrack mutes for beats one/two and picks back up on beat three.
If that accomplishes what you are attempting, render the mix to a WAV file, import that WAV onto the Audio Track and Move the Audio to a Performance Track to replace your original RealTrack file. This bounces your two track mix onto a single audio file and frees up two tracks and makes the mix permanent as a audio performance track.
