Since CorOS 2.1.0 the tuner can be activated/deactivated via specific MIDI CC values. That allows me to program the tuner for a silent guitar changeover between songs. So I activate the tuner for the muting function, switch the preset to the next song (both via MIDI), switch the guitar, check the tuning, and then deactivate the tuner via MIDI again.
I guess, since the update the tuner will be deactivated when changing the preset, maybe when changing scenes but I’m not sure about my last thought. I would like to see the tuner stay activated or a setting to configure that behavior.
