This instrument was inspired by a bet between Ray Kurzweil and musician <a href="/wiki/Stevie_Wonder" title="Stevie Wonder">Stevie Wonder</a> 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 <a href="/wiki/Read-only_memory" title="Read-only memory">ROMs</a> were developed and issued for both models. </p> <div class="mw-heading mw-heading3"><h3 id="K150_synthesizer">K150 synthesizer</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Kurzweil_Music_Systems&action=edit&section=3" title="Edit section: K150 synthesizer"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>As opposed to using 'sample-based' or 'subtractive' synthesis, the K150 (a rack-mount unit) uses <a href="/wiki/Additive_synthesis" title="Additive synthesis">additive synthesis</a>. <a href="/wiki/Hal_Chamberlin" title="Hal Chamberlin">Hal Chamberlin</a> (mentioned below) developed software to run on Apple II class computers, which would allow extensive control of the very rich possibilities of the K150.

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). </p> <div class="mw-heading mw-heading3"><h3 id="K2xxx_synthesizers">K2xxx synthesizers</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Kurzweil_Music_Systems&action=edit&section=5" title="Edit section: K2xxx synthesizers"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure typeof="mw:File/Thumb"><a href="/wiki/File:Kurzweil_K2000_top.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/5/57/Kurzweil_K2000_top.png/300px-Kurzweil_K2000_top.png" decoding="async" width="300" height="101" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/5/57/Kurzweil_K2000_top.png/450px-Kurzweil_K2000_top.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/5/57/Kurzweil_K2000_top.png/600px-Kurzweil_K2000_top.png 2x" data-file-width="1532" data-file-height="514" /></a><figcaption>K2000 (1991)</figcaption></figure> <p>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 <a href="/wiki/Variable_Architecture_Synthesis_Technology" class="mw-redirect" title="Variable Architecture Synthesis Technology">Variable Architecture Synthesis Technology</a> (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. </p><p>The <a href="/wiki/Kurzweil_K2000" title="Kurzweil K2000">K2000</a> was released in 1991 and was initially available in four versions, the K2000, K2000S, K2000R, and K2000RS. The S versions contain the hardware required for <a href="/wiki/Sampling_(music)" title="Sampling (music)">sampling</a>, while the R versions are rack-mountable; the versions without an R feature 61 pressure-sensitive keys. The K2000 is capable of 24 voice <a href="/wiki/Polyphony_(instrument)" class="mw-redirect" title="Polyphony (instrument)">polyphony</a>, 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 of sample 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. </p> <figure typeof="mw:File/Thumb"><a href="/wiki/File:Kurzweil_K2000R.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/5/55/Kurzweil_K2000R.png/140px-Kurzweil_K2000R.png" decoding="async" width="140" height="39" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/5/55/Kurzweil_K2000R.png/210px-Kurzweil_K2000R.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/5/55/Kurzweil_K2000R.png/280px-Kurzweil_K2000R.png 2x" data-file-width="1490" data-file-height="411" /></a><figcaption>K2000VPR</figcaption></figure> <p>The K2500R and K2500/K2500X, released in 1995 and 1996 respectively, were substantial improvements to the K2000R and K2000, increasing polyphony to 48 voices and supporting up to 128MB of sample RAM. The K2500 and later K2600 models can have a single patch running 192 virtual oscillators.

KDFX was also offered as an upgrade for the K2500 and later made available as a standalone product in the KSP8. KDFX drastically improved the quality of effects over the K2000 and K2500's built-in effects units, and added more flexibility such as using the Kurzweil as a vocoder. But the most impressive feature of the K2600 was Kurzweil's 'Triple Strike Piano', which was one of the most realistic-sounding sampled pianos available at the time. Patches for the K2500 were completely redesigned to incorporate the KDFX and triple strike capability. The K2600 uses different type sound expansion ROMs than the K2500 (although they contain the same samples), and could have a classic keys and <a href="/wiki/General_MIDI" title="General MIDI">General MIDI</a> (GM) sound set added. </p><p>All K2000, K2500, K2600 and their rack mount versions can host one internal <a href="/wiki/SCSI" title="SCSI">SCSI</a> hard disk, using the appropriate factory kit (data cables, power cables, and mechanical adapters). The capacity of disks is up to 8GB split into 2GB partitions. </p><p>The K2661, released in 2004, is basically a full-featured K2600 with a 61-key keyboard, flash memory storage, and a redesigned sound set that includes the expansion sets that had been produced for the K2000, K2500, and K2600. The other difference from the K2500 and K2600 is that there is no built-in ribbon controller, although a Kurzweil external ribbon unit can be fitted via a <a href="/wiki/6P6C" class="mw-redirect" title="6P6C">6P6C</a> telephone-like connector. By design, it is not possible to mount an internal hard disk, however external SCSI storage units can be connected to the <a href="/wiki/DB-25" class="mw-redirect" title="DB-25">DB-25</a> <a href="/wiki/SCSI_connector" title="SCSI connector">SCSI connector</a> on the rear of the instrument. </p><p>In 2008, all K26xx series synthesizers were discontinued by Kurzweil Music Systems, although inventory still remained as of August 2008<sup class="plainlinks noexcerpt noprint asof-tag update" style="display:none;"><a class="external text" href="https://en.wikipedia.org/w/index.php?title=Kurzweil_Music_Systems&action=edit">[update]</a></sup>. This left the PC3 and PC3X (which have no sampling capability; see below) as Kurzweil's flagship synthesizers at that time. </p><p>In July 2021 Kurzweil announced a new K2700 flagship workstation. It was released in late 2021 in a 88-key graded-hammer weighted keyboard version. Although marketed as a new product line, the K2700 largely extends the synthesis engine and display and control layout of the Forte and PC-series performance keyboards. While it retains backward compatibility with the earlier K-series and PC-series patches, some of those sound different since certain features of the earlier K-series work differently and the effect processor layout is different.<sup id="cite_ref-sos-k2700_2-0" class="reference"><a href="#cite_note-sos-k2700-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="PCx_Series">PCx Series</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Kurzweil_Music_Systems&action=edit&section=6" title="Edit section: PCx Series"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure typeof="mw:File/Thumb"><a href="/wiki/File:Kurzweil_PC88_setup.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/4/46/Kurzweil_PC88_setup.jpg/165px-Kurzweil_PC88_setup.jpg" decoding="async" width="165" height="124" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/4/46/Kurzweil_PC88_setup.jpg/248px-Kurzweil_PC88_setup.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/4/46/Kurzweil_PC88_setup.jpg/330px-Kurzweil_PC88_setup.jpg 2x" data-file-width="1280" data-file-height="960" /></a><figcaption>PC88  on stage</figcaption></figure> <p>In the mid 90s, Kurzweil introduced the PC88 keyboard, which was advertised more as a <a href="/wiki/MIDI_controller" title="MIDI controller">MIDI controller</a>.

It was perhaps the first of the pure keyboard controllers, brought to market to complement Kurzweil's rack mounted synthesizers. 'MIDIboard' was, in fact, a Key Concepts trademark, transferred to Kurzweil Music Systems as part of a licensing agreement. </p><p>Its novel sensing system, invented and patented by Tripp and Key Concepts co-founder, John Allen, provided velocity, individual <a href="/wiki/Aftertouch" class="mw-redirect" title="Aftertouch">aftertouch</a> pressure, and release velocity information from a single sensor per key. Each sensor was shaped as an arch of <a href="/wiki/Conductive_rubber" class="mw-redirect" title="Conductive rubber">conductive rubber</a> that served as one plate of a capacitor and was designed to deform (change shape under pressure) in a scaled way. The sensors were nicknamed 'sushi sensors' because the first prototype was conductive rubber sheet (think 'nori') held in a barrel shape by a center of white silicone RTV (think 'the rice'). Released in 1988, the MIDIboard's software and electronics were designed under contract to Key Concepts by <a href="/wiki/Hal_Chamberlin" title="Hal Chamberlin">Hal Chamberlin</a>, then of Micro Technology Unlimited. </p><p>The MIDIboard had its virtues and its drawbacks. It was reasonable to manufacture and relatively inexpensive for the range of input forces, both presses and impulse inputs, it could transduce. One of its drawbacks was that it was not well damped in very light playing, making touch uncertain. At some point, working for Kurzweil, Hal Chamberlin debounced this burble. A hardware fix was possible - splitting the sensors. </p><p>It contained a number of interesting innovations, some of which remain fairly uncommon. For example, most MIDI controllers provide aftertouch data, but the Midiboard is capable of <a href="/w/index.php?title=Polyphonic_aftertouch&action=edit&redlink=1" class="new" title="Polyphonic aftertouch (page does not exist)">polyphonic aftertouch</a>, a feature found on few other keyboards. The MIDIboard also provides comprehensive signal routing, layering, and transposition control. These advanced features are not without their cost: the MIDIboard weighs approximately 100 lb and is fairly difficult to use. </p> <div class="mw-heading mw-heading3"><h3 id="Artis/Forte_Series"><span id="Artis.2FForte_Series"></span>Artis/Forte Series</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Kurzweil_Music_Systems&action=edit&section=9" title="Edit section: Artis/Forte Series"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In 2013 Kurzweil released a brand new stage piano called the "Artis". Marketed as "the ultimate all-in-one gigmachine", the Artis is an 88 key weighted action keyboard, in a newly designed, relatively light package of 21 kg. Featuring sounds from the PC3K series and the "Kore64" expansion library, and a user interface focused on easy selection, layering and splitting of sounds, the Artis is aimed at live performance. Also featuring in the Artis is a brand new "German D" grand piano. A newly sampled <a href="/wiki/Steinway_%26_Sons" title="Steinway & Sons">Steinway model D grand piano</a> in six velocity layers with pedal noise effects. Other than aforementioned splitting- and layering abilities, and effects manipulation on pre-programmed controllers the Artis has no on-board editing options. However, a company called "Soundtower" released an editor application for Mac, PC, and iOS devices, allowing for full V.A.S.T. editing. </p><p>In the summer of 2014, the Kurzweil Forte was released as the new flagship stage piano. The Forte is based on the same architecture as the Artis, but with more features. Most notably the Forte has 16GB of "flash play" sample memory used for brand new piano, electric piano and clavinet samples. The same "German D" piano from the Artis is available in the Forte, but far more extensively sampled. The Forte adds two more dynamic layers, and string resonance. By comparison, the German D piano is 128MB in size on the Artis, and 4GB on the Forte. On top of the "German D" the Forte features a "Japanese Grand", which is a sampled Yamaha C7 grand piano, also 4GB in size. Other features are a bigger sound library, bigger effects library, a bigger, full colour display, and more. </p><p>As of April 2016<sup class="plainlinks noexcerpt noprint asof-tag update" style="display:none;"><a class="external text" href="https://en.wikipedia.org/w/index.php?title=Kurzweil_Music_Systems&action=edit">[update]</a></sup>, the Artis and Forte series consisted of 6 models in total:<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p> <ol><li>Artis - the original keyboard as described above</li> <li>Artis 7 - A full featured Artis, but with 76 semi-weighted keys</li> <li>Artis SE - A cheaper, simplified Artis with fewer sounds, fewer effects and fewer controllers.</li> <li>Forte - the original keyboard as described above</li> <li>Forte 7 - A full featured Forte, but with 76 keys (unlike the Artis 7, these are fully weighted keys)</li> <li>Forte SE - A cheaper, simplified Forte with fewer sounds and effects, 128mb versions of both the German and Japanese pianos and only 2GB of "Flash Play" memory.
