Under the Hood: Fatar Keybed & XL Logic Interface

The SL88 GT MK2 isn’t just flexing its looks—underneath, it’s packing Fatar’s latest fully weighted keybed. Doctor Mix can’t hide his excitement, and honestly, neither would we. The tactile response is the kind of thing you need to feel to believe—think less ‘MIDI controller’, more ‘grand piano with a tech upgrade’.

The upgraded XL Logic interface is all about speed and clarity. Two levels deep and you’re into everything you need: zones, MIDI ports, splits, and more. No endless menu-diving, just direct access. MIDI 2.0 support is onboard too, future-proofing your setup for whatever comes next. If you want a controller that doesn’t slow you down, this is it.


Zone Wars: Layers, Splits, and Sonic Mayhem

So it's very super flexible and the logic remains the same for each zone.

Doctor Mix dives into the zone setup, showing off the SL88 GT MK2’s ability to handle four independent zones. Each zone can be tweaked, muted, layered, or split—perfect for those who like their live sets messy and their studio sessions even messier. The workflow is quick: pick a zone, set a key range, dial in your MIDI port, and you’re off.

He demonstrates layering a synth pad with a piano, flipping between sounds and key ranges with minimal fuss. The interface keeps things logical, so you’re not left guessing what’s going where. If you’re the type who likes to build Frankenstein patches, this board’s got the flexibility to keep up. For the full mayhem, though, you’ll want to watch Doctor Mix in action—words don’t do the chaos justice.

SL Link: Mirror, Mirror on the Screen

Here’s where things get clever: the SL Link protocol. One button and you’re mirroring everything from the keyboard onto your device—Numa Player on Mac, Windows, or even your iPhone. Doctor Mix is clearly impressed, and it’s easy to see why. No more squinting at tiny LCDs or guessing what’s loaded—what you see on the board is what you see on the screen.

SL Link isn’t just for show, either. It promises future plugin support, making this controller a bit of a forward-thinking beast. If you’re tired of clunky software integration, this is a breath of fresh air. The real magic is in the workflow, and honestly, you’ll want to see the mirroring in action to get the full effect.

The SL button is what activates the protocol that allows you to mirror what happens on Numa player and the master keyboard itself.
