I’m using the Rec button for automation (e.g. CC1 &CC11), but I hate the sound of a metronome. Especially for expression work which is playing against an entered line and doesn’t need a metronome. What I use over in Logic is a MIDI Solutions Beat Indicator which is a device that takes a MIDI signal and flashes the beat on an LED, just like a silent metronome. The setup in Logic is the following
The MIDI Click configures the beat to the same settings in the Beat Indcator. Easy and works great without having my head drilled by a metronome.
So I’d gently suggest at least a way to turn off the record metronome, a better solution would be similar to what Logic did, with the settings shown above. Specifically at least the ability to tweak the metronome sound more, and also the ability to send out a MIDI message as Logic does so that external gear can synchronize off of that.
