The Qun MK2 has LED buttons and external processor for UI processing. SD card support is included (SD card supplied in box). This is a real synth, not preset machine. Great as a pocket music sketch tool or in a DAWless setup.

This item is not beginner-friendly due to menu-diving on a tiny LCD screen. Comes with DIN to 3.5mm MIDI adapter, USB-C cable, fabric carrying bag and (16 GB) SD card. This item has not been used, so is brand new.
