Donner DMK-25 Pro, A Portable MIDI keyboard

Donner is upping its portable MIDI keyboard with the release of the DMK-25 Pro, a feature-rich 25-note controller. The DMK-25 Pro, is a portable MIDI keyboard that promises “a complete music production experience”

The 25 black keys are mini ones that respond to velocity, as do the eight backlit pads. Further control options include ptchbend and modulation touchstrips, four assignable knobs, four assignable sliders, eight function buttons, six transport buttons and an OLED display.

Dynamic Scale Mode, locks the keyboard to specific notes and scales so your playing won’t sound ‘wrong’. This gives you access to 16 modal scales that Donner says are suitable for playing Chinese, Japanese and Middle Eastern music.

Other performance features include an arpeggiator, note repeat and a chord generation function, fall under the Real-time Multi-Mode Control banner

The DMK-25 draws its power over a USB-C port, and also offers a 3.5mm jack MIDI out for connection to mini hardware synths and the like.
