Listen/Solo toggle preference. When pressing a solo button on a hardware controller it normally activates the [S]-solo button on the chosen track, soloes the track in the monitors AND the Cue Sends.
If there was a Preference setting to toggle the [L] and [S] buttons it would mean that a track could be soloed in the monitors but not interrupt whatever mixes are being sent to the Cue Sends.
Or is there already a way to solo a track in the monitors but not in the Cues Sends just by using the [S] buttons?
