Kurzweil PRO-76
A 76-note weighted controller that carries the same sound engine as the flagship K1200 Professional — and a serious investment at $2,595.
Overview
Fifty-five pounds of injection-molded flat black casing, a weighted-action keyboard with plastic keys, and a sound engine lifted straight from the K250. The Pro 76 was Kurzweil's answer to the player who wanted the flagship voice architecture in a smaller, stage-friendly footprint — and the company charged accordingly. At $2,595 it was, as Electronic Musician put it, "a significant investment in an age where money doesn't do what it used to."
The Pro 76 sits in the K1200 series alongside the 88-key K1200 Professional and the 2U rack-mount Pro 1, and it is virtually identical to the 88-key model except for the number of keys. The voice architecture is shared across all three: 24-voice polyphony, 16-part multitimbral operation, and 6 MB of sound ROM. Mix (October 1990, p.262) noted the Pro 76 offered the same features as the K1200 Professional in a 76-note weighted keyboard, with the product introduced in June 1990. The sample-based synthesis technology descends from the K250, and the Pro 76 carries 162 preset Programs plus 93 RAM locations for user-defined Programs — a broad palette spanning the signature Kurzweil piano, modified grands, brass, percussion, string sections, and guitars.
The keyboard itself is one of the Pro 76's strongest arguments. The weighted action is expressive and playable, and the plastic keys help keep the weight down to a respectable 55 pounds without sacrificing too much feel. There is a catch, though: while the sound generator can receive polyphonic aftertouch, the keyboard transmits only monophonic aftertouch. For players expecting full per-note pressure response, that is a real limitation, and it is worth knowing before committing.
The control surface is spartan. Two horizontal sliders — one for volume, one for data — a 32-character LCD, and 23 momentary switches handle system access and editing. Those switches are small, closely grouped, and carry no LED status indicators. In a home studio that is a minor annoyance; on a dark stage it becomes a genuine inconvenience. The back panel is equally austere: two pedal jacks programmable for any MIDI switch function, stereo outputs only rather than multiple independent audio outputs, and MIDI in/out/thru. The pedal jacks do auto-detect polarity on power-up, which means pedals of either wiring convention — including the Japanese-style reverse polarity — will work without fuss.
Where the Pro 76 earns its keep is in performance flexibility. The Bin Banks feature organizes memory into three banks (A, B, C) of ten preset Programs each, with a dedicated button per Program, giving instant access to 30 sounds. Each group of 30 can be stored as a Bin Map, and multiple Bin Maps can be named and saved — a genuinely useful concession given how long it otherwise takes to scroll through the instrument's memory. Performance Setups split the keyboard into three non-overlapping zones, each configurable for local control, MIDI control, or both, with independent MIDI channel and controller assignment per zone. Up to 255 Performance Setups can be stored, subject to available memory.
Kurzweil's approach to velocity and amplitude deserves mention. Rather than offering a handful of preset amplitude curves, the Pro 76 provides Keyboard Tilt — a programmable amplitude curve that applies a progressive volume change from the lowest note to the highest across any selected region. Velocity is handled through maps: one global velocity map, eleven built-in maps for emulating other keyboard architectures when triggering the K1200 from external controllers, and the ability to create custom velocity and pressure maps. Velocity crossfading works between stacked layers and overlapping regions. Group transposition is selectable by region, and onboard diagnostics include a MIDI data monitor.
The MIDI implementation is comprehensive, and anything that can be named and saved can be exported via SysEx dump commands. A Midiscope mode displays transmitted or received MIDI events — time between events in milliseconds, event type, channel, key velocity, and key number. The manual is well-written, which matters because the K1200 is a sophisticated instrument without a lot of onboard prompts to guide programming. ObjectMover software, available for Macintosh, IBM PC, and Atari ST, moves programs back and forth and stores up to 8,000 MIDI events in the 64K Demo RAM buffer, which is shared between sequence and patch data. The Macintosh version includes a MIDI File Converter for Type 0 Standard MIDI Files.
Context matters here. By the time the Pro 76 reached reviewers, Kurzweil Music Systems had been acquired by Korean piano-maker Young Chang, and company representatives promised the original R&D department would remain intact with new funding behind it. The K1200 series was not a next-generation design so much as the flagship of Kurzweil's then-current lineup — a refinement of the K250-derived architecture rather than a departure from it. Electronic Musician's reviewer came away impressed: the Pro 76 was, in that assessment, a must-see for anyone needing a good controller that sounds absolutely dynamite, and the magazine's product summary awarded top marks for features, ease of use, and audio quality, with value scoring lower — the price was the sticking point.
For collectors and players today, the Pro 76 occupies an interesting position. It is a Kurzweil of the Young Chang era, sharing its engine with the K1200 Professional and Pro 1, and it delivers the company's signature piano and sample-based sounds through a weighted 76-note action. The monophonic aftertouch and the stereo-only outputs are the compromises; the Bin Banks, three-zone Performance Setups, and deep velocity/pressure mapping are the rewards. It is not a lightweight stage piano, and it is not a budget instrument — but for someone who wants the K1200 architecture without the 88-key footprint, it is a specific and characterful choice.
