Sound tone control for cue preview

[discopex]

This is a feature found on some hardware mixers, a knob that controls the cue preview sound tone, kinda bi-filter that emphasizes either bass or treble frequencies. This is something I absolutely love since I prefer my in-ear sound warmer than what goes out the mixer. So if I ever was to go for a MIDI mixer this is something at I would need in-the-box. Do you catch my drift ?
