Akai Opens MPC Sample Key Firmware to Modders Before Official Launch
Akai has seeded unannounced MPC Sample Key units to developers, whose mods include Massive ports, virtual analog and FM synths, and custom OS builds. CEO Jack O’Donnell says select software will be open-sourced and an SDK provided.
Akai is giving modders early access to an unannounced device — the MPC Sample Key — and plans to release it with open-source firmware, the company revealed in October 2026 through a series of Instagram Reels posts.
The MPC Sample Key has not been formally announced, but Akai has already seeded units to developers and is showcasing the results. The device runs a version of the software found on the existing MPC Sample, modified to support a traditional keyboard layout along with pitch and mod wheels. Unlike the higher-end MPC Key 37, the Sample Key does not include pads — samples are played back directly via the keys.
The Instagram clips show several community-built modifications, including ports of Native Instruments Massive, virtual analog synths, and FM synths. One clip shows the device running a fully custom operating system containing “several different synths.” Some of the synths shown were built using Claude, an AI coding tool, through a process the posts describe as vibe coding.
Akai CEO Jack O’Donnell told The Verge that inMusic brands, particularly Akai, intend to support the modding community by seeding early hardware to developers, open-sourcing select software, and providing an SDK.
The same community features are also coming to the standard MPC Sample, which was shown running several vibe-coded synths in the clips. This could suggest Akai is considering open-sourcing the broader MPC Sample platform, though no formal announcement has been made.
The move signals a potential shift in how Akai approaches third-party development, giving independent developers tools and hardware access before a product even reaches an official launch stage.
