Kurzweil K1200 (1990)
A 24-voice, 162-sound professional synth whose own maker promised it wouldn't give you programming heartaches.
Overview
The K1200 arrived in mid-1990 as Kurzweil's pitch to the working keyboardist who wanted the company's clean sample library without a steep learning curve. The ad copy ran in the trade magazines and was almost disarmingly sentimental: 162 sounds, each built from four layers, run through an onboard effects processor, with 16-channel multitimbral operation and dynamic voice allocation rounding out the "fully professional synth for the 90s" package. Mix (October 1990, p.262) logged the product introduction and confirmed the core architecture - 6.0 MB of sound ROM, aftertouch, MIDI in/out/thru, and stereo outputs. Kurzweil leaned hardest on ease. Its own copy said the K1200 featured "the easiest programming ever."
The 162-sound library is the heart of the thing, and it is a very Kurzweil library: acoustic pianos, electric pianos, acoustic and electric guitars and basses, drum kits, percussion, synth clavs, lead synths, bells, brass, trumpets, tenor saxes, strings both orchestral and pop, harps, marimbas, vibes, choirs, woodwinds, organs, synth pads, and effects. All of it comes from 6 MB of sound ROM. The four-layer structure per sound gives the presets their weight. A piano isn't a single sample stretched across the keyboard but a stack that can be processed, modulated, and combined. The onboard effects processor does a lot of the perceived heavy lifting, and the 24-voice allocation is generous for the era - enough to hold a layered pad and a bass line without note-stealing drama.
The K1200 was sold in two keyboard forms: an 88-note and a 76-note version, both with weighted, velocity- and pressure-sensitive actions. The 76-note variant carried its own model designation, the Pro 76, and Mix's new-products column (October 1990, p.262) described it as offering the same feature set as the K1200 Professional in a 76-note weighted keyboard. For players adding Kurzweil sounds to an existing rig, Kurzweil put the same engine into the Pro I rackmount expansion module. Per the company's advertising, it was a newly engineered rack version of the K1200, priced at $1595, with 16-channel multitimbral operation and the same easy programming. The module shared the 24-voice polyphony and the 162 acoustic, electric, and synthesizer sounds. It could also arrange them into 10 programmable lists of up to 100 entries each, with extended program changes reaching up to 1000 entries. A 24 Kbyte battery-backed setup RAM stored user programs, performance setups, and maps.
Pricing is muddy, so collectors should pay attention to which figure they're citing. Kurzweil's own 1991 advertising for the Pro I module quoted $1595, but the dealer listings from the same period tell a different story. One retail advertisement showed the K1200 at a list of $2295 discounted to $1995, and the Pro 76 at a list of $2595 marked down to $1760. An Electronics Musician show report from the period quoted the K1200 at $3195 for the 88-note keyboard, with the Pro I at $1795, the Pro II at $1695, and the Pro III at $1495. Those figures don't reconcile neatly with the dealer sheets. They likely reflect different configurations, dates, or the usual show-report fuzziness. The safe reading is that the K1200 was a roughly two-thousand-dollar keyboard at street, and the Pro I module landed near fifteen hundred. Treat the original MSRP as approximate.
The "easiest programming ever" line was a positioning statement aimed at players who wanted to call up a sound and play it, not build one from oscillators up. That's the split in the used market: the K1200 suits someone who wants Kurzweil pianos, strings, and pads in a weighted controller with straightforward multitimbral routing, not someone hunting for a deep synthesis engine. The four-layer architecture and the effects processor give it more sculpting room than the preset count suggests, but the interface rewards patience rather than inviting exploration.
Mechanically, the weighted, pressure-sensitive keybeds are the long-term question mark on any K1200 that surfaces now. Actions of this vintage are the first thing to need attention, and the 88- and 76-note versions are the parts most likely to have seen heavy gigging. The 24 Kbyte battery-backed setup RAM is the other aging point. A dead backup battery means lost user programs, so confirm the memory holds before buying. The Pro I module sidesteps the keybed question entirely. It is the cheaper way into the sound set for a studio already stocked with controllers - the same 162 sounds and 24-voice engine in a rack, at a fraction of the keyboard's footprint and price.
As a collectible, the K1200 sits in an awkward spot. It has the company's signature sample quality and a usable multitimbral spec, but collectors pay more attention to the deeper K-series instruments. The Pro I module is a cheap way to get the Kurzweil sound into a rack without paying keyboard money, provided the buyer accepts the preset-forward approach and the 6 MB ROM ceiling.
