  • Hundreds of additional sounds

Legendary Triple Strike Grand Piano, plus other keyboards
The PC3X is loaded with the famous Kurzweil Triple Strike Piano, with dozens of variations to accommodate every kind of player. Also included is the Classic Keys ROM, which puts an impossibly large vintage keyboard rig at your fingertips. The recognizable sounds of classic electromechanical instruments, with all of their characteristic imperfections, have been faithfully re-created, along with pedals, amps and speakers. Lush Mellotrons, growling electric pianos, and funky Clavinets are all there at the touch of a button, programmed to sound just like those classic albums. For more vintage firepower, the PC3X is equipped with the most advanced version of Kurzweil's widely lauded KB3 Mode tonewheel organ simulator, which screams, sputters and sizzles just like the original. In addition to newly developed Leslie effects, and a new bank of B3 programs, we've also included sounds from the classic Vox and Farfisa combo organs. The PC3X's nine sliders provide real-time drawbar control.

Amazing new features in version 1.3
PC3 Version 1.3 has just been released, and Sweetwater is the only place you'll find it! We're updating all PC3s and PC3Xs to the latest version before shipping them. This OS upgrade officially brings the PC3s to a "feature complete" status.

PC3 Operating System 1.3 Features:
  • Dual Step Sequencers Per Zone in Setups: This allows up to 16 simultaneous step sequences at once with a large collection of pre-recorded patterns, scales, modes, and riffs available.
  • Seamless Program Switching: Go from one program to the next while dialing up another sound. The previous notes stay and (in an industry first) the old effects stay on the old sound along with the new effects of the new sound! This is so musical; you must try it yourself.
  • Clickless Portamento on Samples: Again, an industry first. You can now glide across the keyboard, using monophonic portamento, and the samples won't click as they run through the keymap.
  • Two New VA-1 Oscillators: Kurzweil is still including the entire VA-1 Virtual Analog Synthesizer for free. And now, they've added two new oscillators: Triple Saw and Square Sync (think of songs by The Cars).
  • Plus, there are many, many new Programs, Setups, and Effects.

Hundreds of additional sounds
The PC3X offers an enormous sound set of over 800 programs. With some of the best samples in the industry, and a powerful, responsive synth engine breathing life into them, you'll feel like you're playing an actual instrument, not just playing samples. All of the basic sounds - basses, guitars, drums, horns and synths - have been painstakingly programmed to reflect the needs of today's professional players, representing a broad selection of styles and flavors from the '60s, '70s, '80s, '90s and today. In addition, the PC3X includes over 250 orchestral and string section programs.

Amazing effects power
With up to 16 insert effects plus two auxiliary sends, the PC3X offers more than twice the processing power of Kurzweil's acclaimed KDFX engine. Effects can be chained together in series, or distributed among the PC3X's 16 multitimbral channels. And these are simply the best effects in the business - burning distortions, transparent compressors, warm phaser and chorus effects, perfect reverbs - everything from flawless vintage emulations to concert halls which decay into complete silence. All parameters are assignable to any of the PC3X's real time controllers - sliders, pedals, wheels, etc.

Powerful onboard sequencer
For good measure Kurzweil included a 16-track sequencer. Combining a set of powerful song editing functions like step editing, swing, and controller scaling with a new friendlier interface, the PC3X can easily double as a workstation, ideal for music production on the fly. Also included are sixteen (yes, 16!) independent arpeggiators as well as hundreds of pre-recorded beats and musical phrases. Add in USB, Flash card port, a newly designed keyboard action, and a new intuitive user interface, and you've got a workstation-grade keyboard in the PC3X.

Custom-designed chips for premium sound quality
One thing which clearly sets Kurzweil apart from the competition is the fact that they design their own chips (called ASICs) for all Kurzweil products. Simply put, these chips are customized for optimum audio performance. Some other manufacturers use general-purpose DSP chips commonly found in cell phones, watches and televisions. What does this mean for the end user? It means that all of the processing power in a Kurzweil chip is devoted exclusively to sound. It means no latency - the performance is lightning fast. And most importantly, it translates into that rich, full, glitch-free sound for which Kurzweil has become famous.

Incredibly powerful Dynamic V.A.S.T. synth engine
The PC3X's new Dynamic V.A.S.T. architecture is a huge step forward in
synthesis, the fruit of several major strides Kurzweil has made in improving
processing power, flexibility and user-friendliness.

VA-1 Virtual Analog Synthesizer built in
In another huge development, Kurzweil has resurrected the VA-1 Virtual Analog
Synthesizer, having built its synthesis engine right into the PC3X. Hear the VA-1's power-shaped, anti-aliasing oscillators combined with a newer, larger set of V.A.S.T. filters and non-linear processors and you'll understand why the internet is buzzing about this feature.

Revamped, easy-to-use interface
While the PC3X's user interface may look familiar to veteran Kurzweil users, major improvements have been made, allowing for a much more user friendly experience. Expanding upon Kurzweil's V.A.S.T. architecture, the PC3X's new UI delivers all the power of a Kurzweil, combined with unprecedented ease of use. The PC3X's backlit 240 x 64 display conveys all the information you'll need, when you need it, in an elegant, easy to navigate environment. All programs and setups are accompanied by help messages which can be accessed by pressing an "Info" soft button.
