What it is the best way to go for transposing a track and there is a way to transpose multi track in one operation Thank you

Hi Alrobi, Do you mean MIDI tracks? Select all the regions on a track by clicking on the track header and in the Inspector choose the transposition value from the the "Transposition" item. To transpose multiple tracks, shift click on the track headers to select all the regions on those tracks and do the same as the above. Cheers Rounik

Sorry i mean when you work with Software Instrument track midi controller+sampling

That's fine! I also meant software instrument tracks. Follow the steps in my previous post. It will work fine. Cheers Rounik
