I use my QU24 to record stereo tracks on a regular basis & assigned 2 soft keys to QU-DRIVE STEREO REC to arm the recording, as well as QU-DRIVE STEREO PLAY to start the recording. There is no way of pausing / stopping the recording using a soft key once the recording has started. Would be nice to have more functionality with the soft keys, so you can at least stop the recording without having to go into QU-DRIVE screen each time, especially if using the screen to monitor other features on the console.
Additional features / shortcuts that can be assigned to soft keys will also be great. Sometimes getting to a certain menu or feature that is used often can only be accessed after going through a number of layers. Would be nice to assign important features (for ex. RTA, etc) to soft keys for easy accessibility.
