Before I go into bass/drum sessions (I use a different studio) I always make all the tracks, scratch or main keys, acoustic guitar, vocals, tempo map, and the designated tracks for the bass and drums. I also of course need a metronome. All is fine - until - the drummer wants plus 6db volume and a different tone. I go into the metronome, reset it, and when I go back into track recording mode the metronome no longer works. I then have to hurriedly make a midi metronome with the TTS or my external keyboard. What is that?
