Product guide

Synido TempoKEY K25 25-Key USB MIDI Controller

The Synido TempoKEY K25 is a 25-key USB MIDI controller with velocity-sensitive keys, drum pads and onboard MIDI editing. Its arpeggiator, assignable controls and compact format suit hands-on music production, but it does not produce sound on its own.

At a glance

The keyboard has an onboard OLED display and encoder for changing MIDI parameters without relying entirely on computer-side editing.
Its arpeggiator offers adjustable timing and multiple modes, while velocity-sensitive keys and pads allow performance dynamics.
Eight assignable knobs offer two banks for up to 16 controls. Six transport buttons are listed for DAW control.
USB-C connectivity is described for data and power, with claimed 1/8-inch MIDI output and 1/4-inch sustain input.
This is a MIDI controller, not a standalone sound-producing keyboard.

What to know before buying

Listing details to confirm

Listing details are inconsistent: USB is labelled as a wireless connection despite USB-C being described, interface details list 1/4-inch and 3.5mm audio while feature text specifies a 1/4-inch sustain input and 1/8-inch MIDI Out, and the claimed phone, tablet and computer compatibility is not uniformly confirmed by customer feedback. Confirm the exact connections and host setup for your intended device before buying.
