Practice Studio — screen mockups

Five screens drawn at the Galaxy Z TriFold's real unfolded size (2160 × 1584 px, 204.8 × 150.2 mm). Every fret and key is placed at its true millimetre position. Pink numbers are for comments: just say e.g. "A5 too busy" or "B4 make bigger". Faint dashed lines are the two folds.
