FLkey 2 37

FLkey 2 37 is a 37-key MIDI keyboard controller built specifically for FL Studio. Three octaves of full-size, synth-action keys sit under a control surface mapped to the parts of FL Studio you touch most: the Channel Rack, Step Sequencer, Mixer, Playlist, and plugin parameters. Connect over USB-C and the mapping is already done, so sessions start with playing rather than assigning controls.

Sixteen RGB pads cover step sequencing in the Channel Rack and finger drumming with FPC, SliceX, and Fruity Slicer. Each pad reads velocity and polyphonic aftertouch, so pressure applied after the hit can move filter, pitch, or any parameter a plugin exposes. Eight endless encoders handle levels, sends, filter sweeps, and effect settings, and the OLED display names whatever you are adjusting instead of leaving you to guess from knob positions.

The creative tools live in the hardware. Scale mode locks the keybed to a chosen key, Fixed Chord mode triggers a full chord from a single key, and Chord Maps spread progressions across the pads. The arpeggiator builds and mutates sequences for melodic or rhythmic parts, and it all works the same way with outside gear as it does in the DAW.

Beyond FL Studio, the full-size 5-pin MIDI output connects hardware synths and drum machines with no computer in the chain. Mackie HUI support covers other DAWs, Novation Components builds custom pad and encoder layouts for plugins or outboard gear, and NKS support gives two-way communication with Native Instruments software.

The included bundle covers a six-month trial of FL Studio Producer Edition, Novation Play, Melodics lessons, GForce synth emulations, Klevgrand LUXE and Slammer, Orchestral Tools Parallel Orchestra, and Native Instruments Komplete Select. The controller is class compliant and USB bus powered, so it also works with recent Mac, Windows, and iOS devices.
