I open a file called Click.MId that has the rimshot on every quarter note for 100 bars (I do this in RB, but assume it might work in other PGMusic products)
Then I set the tempo I want, make that Midi track into an audio track and I'm on my way

I don't think you can convert the actual metronome, but that is my workaround and then mute the default metronome so I hear only my new audio click ..


I do not work here, but the benefits are still awesome
