I have EarMaster 5 on my work computer and my home computer. On my home computer, the notes are playing 1 octave lower than they should on a guitar. On my work computer they are playing correctly.
Any idea how to fix the problem on my home computer?
Try to go to: Tools, Program Settings, Transposing Instruments under the environment tab, and check that it is set to 0 (C) Non Transposing (Standard).
