Can I shift layout from left to right
To up to down.
That would be a lot useful. Most softwares are in up to down layout. It will be helpful for everyone
Most software isn't up and down. Only trackers are. Any DAW like Garageband, Logic, Pro Tools, Audacity, etc all use the horizontal layout. It might be best to get accustomed to it
most of piano type DAWs have horizontal layout.
