Kurzweil Music Systems is an Amer­i­can com­pany that pro­duces elec­tronic mu­si­cal in­stru­ments for pro­fes­sion­als and home users. Founded in 1982 by Ste­vie Won­derRay­mond Kurzweil, a de­vel­oper of read­ing ma­chines for the blind, and Bruce Ci­chowlas, a soft­ware de­vel­oper, the com­pany made use of many of the tech­nolo­gies orig­i­nally de­signed for read­ing ma­chines and adapted them to mu­si­cal pur­poses. They re­leased their first in­stru­ment, the K250 in 1983, and have con­tin­ued pro­duc­ing new in­stru­ments ever since.

The com­pany was ac­quired by Young Chang in 1990. Hyundai ac­quired Young Chang in 2006 and in Jan­u­ary 2007 ap­pointed Ray­mond Kurzweil as Chief Strat­egy Of­fi­cer of Kurzweil Music Systems.

K250 synthesizer

Main article: Kurzweil K250
 K250 (1984)
K250 (1984)

The com­pany launched the K250 syn­the­sizer/sam­pler in 1984: while lim­ited by today's stan­dards and quite ex­pen­sive, it was con­sid­ered to be the first re­ally suc­cess­ful at­tempt to em­u­late the com­plex sound of a grand piano. This in­stru­ment was in­spired by a bet be­tween Ray Kurzweil and mu­si­cian Ste­vie Won­der over whether a syn­the­sizer could sound like a real piano. First is­sued as a very large and heavy key­board, the elec­tron­ics were also is­sued in a very large and heavy rack­mount ver­sion, as the 250RMX (Rack Mount "Ex­pander"—the pre­sumed in­ten­tion being that one could drive via MIDI and se­quencers one or more "ex­panders"). Ad­di­tional sam­ple ROMs were de­vel­oped and is­sued for both models.

K150 synthesizer

As op­posed to using 'sam­ple-based' or 'sub­trac­tive' syn­the­sis, the K150 (a rack-mount unit) uses ad­di­tive syn­the­sis. Hal Cham­ber­lin (men­tioned below) de­vel­oped soft­ware to run on Apple II class com­put­ers, which would allow ex­ten­sive con­trol of the very rich pos­si­bil­i­ties of the K150. This syn­the­sizer was never a com­mer­cial music suc­cess, but was very pop­u­lar in aca­d­e­mic and re­search facilities.

K1xxx synthesizers

The K1000 and K1200 (and their rack-mounted vari­ants) were de­signed to de­liver the sam­ple li­braries de­vel­oped orig­i­nally for the K250 to a wider au­di­ence in less ex­pen­sive and phys­i­cally more man­age­able forms. Un­like the K250, these in­stru­ments could not sam­ple new sounds di­rectly; but their pro­gram­ming ar­chi­tec­ture and op­er­at­ing sys­tem were evo­lu­tion­ary steps that would cul­mi­nate in the K2xxx se­ries. There were sev­eral key­board ver­sions is­sued, and the 1000 mod­ules were orig­i­nally is­sued in PX (pi­anos and mixed bag), SX (strings), HX (horns and winds), and GX (gui­tars and basses) ver­sions, each with dif­fer­ing sam­ple-ROMs. As com­put­ing and elec­tron­ics tech­nolo­gies changed rapidly dur­ing the pe­riod, larger sam­ple bases could be com­bined. The later 1200 mod­ule ver­sions con­tained these larger sam­ple bases (i.e., PX+SX; SX+HX; HX+GX).

 K2000 (1990)
K2000 (1990)

The com­pany's flag­ship line of syn­the­sizer work­sta­tions, the K2xxx se­ries, began to make real head­way with the K2000, which in­tro­duced the com­pany's ac­claimed Vari­able Ar­chi­tec­ture Syn­the­sis Tech­nol­ogy (V.A.S.T.) en­gine. Through­out the 1990s, up­dates and up­grades to the K2000 (and even­tu­ally its suc­ces­sors, the K2500 and K2600) en­sured that the K2x se­ries was re­garded as one of the most pow­er­ful and best-sound­ing syn­the­siz­ers/sam­plers avail­able. Al­though ini­tially very ex­pen­sive, Kurzweil in­stru­ments were pop­u­lar in top record­ing stu­dios and for use with music pro­duc­tion for film be­cause of their high-qual­ity sounds.

The K2000 was re­leased in 1990 and was ini­tially avail­able in four ver­sions, the K2000, K2000S, K2000R, and K2000RS. The S ver­sions con­tain the hard­ware re­quired for sam­pling, while the R ver­sions are rack-mount­able; the ver­sions with­out an R fea­ture 61 pres­sure-sen­si­tive keys. The K2000 is ca­pa­ble of 24 voice polyphony, which is some­what lim­ited, al­though up to 3 os­cil­la­tors per voice can be used and an in­tel­li­gent voice steal­ing al­go­rithm re­tires the play­ing notes which are es­ti­mated to be least au­di­ble rather than sim­ply the old­est. Each voice of the K2000 is able to play a sep­a­rate pro­gram, al­low­ing for smooth tran­si­tions dur­ing live per­for­mance - this sim­ple fea­ture took Kurzweil's com­peti­tors more than a decade to match. The key­board came with 2MB RAM but could be equipped with up to 64 megabytes of RAM for user loaded sam­ples. Later mod­els in­cluded the K2000VP (key­board), K2000VPR (rack), K2VX (key­board w/ op­tional ROMs), and K2VXS (key­board w/ op­tional ROMs + sam­pling), which were based on the same hard­ware as the K2000 se­ries but had the K2500 sound set loaded.

The K2500, re­leased in 1996, was a sub­stan­tial im­prove­ment to the K2000, in­creas­ing polyphony to 48 voices and on­board RAM ca­pac­ity to 128MB. The K2500 and later K2600 mod­els can have a sin­gle patch run­ning 192 vir­tual os­cil­la­tors. There were also a num­ber of other minor im­prove­ments as well as sound ex­pan­sion op­tions (daugh­ter­board + 8mb piano ex­pan­sion, 8MB or­ches­tral ex­pan­sion ROM, 8MB con­tem­po­rary in­stru­ments ROM). K2500 pho­to­graph

The K2500 was avail­able in 7 versions:

  1. K2500 - 76 note semi-weighted keyboard;
  2. K2500X - 88 note weighted action keyboard;
  3. K2500S - 76 note semi-weighted keyboard with sampling;
  4. K2500XS - 88 note weighted action keyboard with sampling;
  5. K2500AES - Audio Elite System, Limited Release (6 Units) 88 note weighted action keyboard with sampling, KDFX effects engine, all available upgrade options, and an extensive sample library (retail cost, $20,000.00).
  6. K2500R - rack-mounted version (no keyboard);
  7. K2500RS - rack-mounted version with sampling.

The key­board mod­els in­cluded a rib­bon con­troller and an input for a breath con­troller, mak­ing them the most ex­pres­sive elec­tronic in­stru­ments avail­able at the time. Ad­di­tion­ally one could add dig­i­tal input/out­put (I/O) to con­nect S/PDIF or ADAT in­puts and a PRAM ex­pan­sion for load­ing larger sound­sets or MIDI songs into mem­ory. If one had pur­chased a model with­out on­board sam­pling, one could add the sam­pling op­tion, PRAM, and re­in­stall their op­er­at­ing sys­tem to have the up­graded model.
