Freshwater Instruments unveils FI50A modern CPU card for Fairlight CMI

Freshwater Instruments has unveiled the FI50A, a $1,500 modern CPU card for the Fairlight CMI Series I, II and IIx that replaces the machine’s original computer section without asking owners to give up the feel of the instrument. The card is due in August or September 2026, and Freshwater says it is meant to keep the CMI’s character, workflow and hardware experience intact while swapping in a far less fragile core.

That matters because the FI50A is not just a drop-in repair part. Freshwater says the card also replaces the original graphics display, memory and library storage, and runs enhanced software derived from the original source code. It adds DisplayPort, USB, Bluetooth and Wi-Fi, plus waveform upload over Wi-Fi and SD and USB memory support, giving a landmark sampler the sort of plumbing its 1980s computer section never had.

Freshwater has also tried to keep the old world around it. The FI50A remains compatible with legacy CMI keyboards, CRT and light pen operation, floppy disks, MIDI interfaces and Series I and II channel cards. Installation is described as straightforward and fully reversible, with the original CPU and peripheral cards removable and preservable. Freshwater says it spent more than a year perfecting the project, which is the kind of timeline that makes sense when the goal is preservation rather than reinvention.

That preservation angle lands hard with the Fairlight because the CMI is not just another vintage synth. Peter Vogel Instruments says the Fairlight CMI, introduced in 1979, was the first commercially available digital sampling instrument, the box that turned natural sounds into playable keyboard parts and helped set the template for later samplers, digital synths and DAWs. The line went on through Series I, II, IIx and III, and the factory libraries became staples in pop, film scores and pseudo-classical work.

Freshwater’s bet is that owners do not have to choose between museum-piece fragility and a full rewrite of what makes a Fairlight a Fairlight. The FI50A keeps the original keyboard, CRT-era workflow and library ecosystem in play, while quietly removing the weakest link in the machine. For a CMI whose reputation was built on rare hardware and heavier maintenance, that is the difference between shelving it and keeping it alive.
