In the sound choices menu in the metronome, under the other choices towards the bottom there is a choice that says "Add Sound". But what should I be doing from there? How do I add a sound? I'd feel more comfortable using a sound that is more earthy and musical than the standard tic-toc metronome sounds provided in Studio One. In Sonar metronome you have the option of assigning Midi Notes to the beats. So I always assigned them to my old Alesis SR-16 drum machine. Much nicer to work with and not as irritating and ear fatiguing than the brash tic-toc.
