Polyend has unveiled a prototype for “Keys,” a hybrid mechanical QWERTY keyboard and MIDI controller designed for simultaneous computer use and music production. According to Polyend, the device features a three-octave piano layout integrated into the number and function rows, allowing users to trigger notes without a dedicated MIDI controller. The prototype was first shown publicly at Gamescom in Cologne from August 26 to 30.
Polyend Keys Hardware and Technical Specifications
The device is constructed from a single piece of machined aluminium and utilizes hot-swappable Kailh low-profile switches. Polyend states that these switches can be replaced without soldering, and the keys include backlighting for visibility. A built-in display allows users to monitor adjustments in real time.
For control, the keyboard includes nine rotary knobs. Polyend notes these can be mapped to MIDI CCs for hardware and software or assigned to standard OS tasks such as brightness, scrolling, and volume. Connectivity is handled via USB and a TRS MIDI output, which allows the unit to function as a standalone controller for drum machines or synthesizers without a computer connection. MusicRadar adds that the device is battery-powerable.
Pro Tip: Hot-swappable switches mean you can customize the “feel” of your typing and playing experience by swapping Kailh switches for other compatible low-profile options without needing a soldering iron.
Open Source Firmware and Customization
Polyend is making the firmware for Keys open source. This decision enables developers and users to create alternative keyboard layouts, custom MIDI tools, and integrated sequencers via software. By opening the code, the company allows the community to expand the device’s functionality beyond the factory settings.

Comparative Context: QWERTY MIDI Evolution
The concept of merging a typing keyboard with musical capabilities is not new, though the execution has evolved. MusicRadar points to Creative’s Prodikeys from the early 2000s as a previous attempt to combine these functions. While Prodikeys failed to gain significant market traction, MusicRadar suggests the sleek aluminium design of the Polyend prototype may offer a more viable appeal to modern producers.
Unlike some hybrids that attempt to squeeze small piano keys onto a chassis, Polyend reconfigures the existing function keys to mirror the positioning of black notes on a musical keyboard. This approach targets users who currently rely on the “musical typing” feature found in most Digital Audio Workstations (DAWs), but provides dedicated hardware controls and MIDI output to move beyond basic software emulation.
Did you know? The function row on the Polyend Keys doesn’t just trigger notes; it is specifically mapped to act as a three-octave piano, providing a wider melodic range than a standard computer keyboard’s MIDI mode.
Current Prototype Status and Availability
Polyend has clarified that Keys is currently a prototype. The company warns that hardware, color, and specific functionality are in early stages and remain subject to change. Neither pricing nor a formal release date has been announced. Potential buyers can sign up for updates on the Polyend website.
Frequently Asked Questions
Does Polyend Keys require a computer to work?
No. According to Polyend, the TRS MIDI output allows it to connect directly to hardware synths or drum machines as a standalone controller.
Can you change the switches on the keyboard?
Yes. The device uses hot-swappable Kailh low-profile switches, meaning they can be replaced without soldering.
Is the Polyend Keys available for purchase now?
No. It is currently a prototype showcased at Gamescom; price and availability are yet to be announced.
