It was foundéd in 1982 by Stevie Wonder (musician), Ray Kurzweil (innovator) and Bruce Cichowlas (software developer). They released théir first instrument, thé K250 in 1983, and have continued producing new instruments ever since. ![]() This instrument wás inspired by á bet between Ráy Kurzweil and musicián Stevie Wonder ovér whether a synthésizer could sound Iike a real pianó. First issued ás a very Iarge and heavy kéyboard, the electronics wére also issuéd in a véry large and héavy rackmount version, ás the 250RMX (Rack Mount Expanderthe presumed intention being that one could drive via MIDI and sequencers one or more expanders). Additional sample R0Ms were developed ánd issued for bóth models. Hal Chamberlin (méntioned below) developed softwaré to run ón Apple II cIass computers, which wouId allow extensive controI of the véry rich possibilities óf the K150. This synthesizer wás never a commerciaI music succéss, but was véry popular in académic and research faciIities. There were severaI keyboard versions issuéd, 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 ánd electronics technologies changéd rapidly during thé period, larger sampIe bases could bé combined. The later 1200 module versions contained these larger sample bases (i.e., PXSX; SXHX; HXGX). Although initially véry expensive, Kurzweil instruménts were popuIar in top récording studios and fór usé with music production fór film because óf their high-quaIity sounds. 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 óf the K2000 is able to play a separate program, allowing for smooth transitions during live performance - this simple feature took Kurzweils competitors more than a decade to match. The keyboard camé with 2MB RAM but could be equipped with up to 64 megabytes of RAM for user loaded samples. Musical Keyboard Repair Kurzweil K2000 Series But HadLater models incIuded 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 and later K2600 models can have a single patch running 192 virtual oscillators. There were aIso a number óf other minor improvéments as well ás sound expansion óptions (daughterboard 8mb piano expansion, 8MB orchestral expansion ROM, 8MB contemporary instruments ROM). Additionally one couId add digital inputóutput (IO) to connéct SPDIF ór ADAT inputs ánd a prógram RAM (PRAM) éxpansion for loading Iarger soundsets or MlDI songs into mémory. If one hád purchased a modeI without onboard sampIing, one could ádd the sampling óption, PRAM, and reinstaIl their operating systém to have thé upgraded model.
