Decades of Sample Technology in One Keyboard!

The Kurzweil PC3 series keyboards introduced some major developments in synthesizer technology, with their anti-aliasing VA oscillators, improved KB3 mode, amazing sound sets, 16 independent riffs and arpeggiators, powerful song and QA modes, sampling, unparalleled MIDI control, and more. If you're a long-time Kurzweil fan, however, you may have missed those wonderful sample libraries you've built up over the years. The PC3K8 changes everything! This revolutionary new keyboard combines all of the hard-hitting PC3 features, plus K 2/25/26 series .K file sample library compatibility, which opens the door to some of the greatest sound sets ever created.

With the PC3K8, you can combine more than a decade and a half of K2000 and K2500 legacy sample libraries with the PC3's super-powerful Dynamic V.A.S.T. synthesis engine, for exploring the uncharted possibilities of sound development. The potential power of the PC3K8 is simply incredible, and 88 PC3X-style fully weighted keys make it a blast to play. It even offers more excellent new features, including a USB host port that lets you plug in standard USB thumb drives so that you can quickly store and retrieve data, as well as load OS updates.

One further development that the PC3K8 offers you is 128MB of nonvolatile user-sample memory. Made possible by a breakthrough in sample flash technology, this nonvolatile user memory adds a new level of stability to the PC3K8. Not only does this new sample flash memory allow the PC3K8 to retain user samples after a power cycle, but it also powers back on with zero sample load time. Whether you're a Broadway performer, a working musician, a composer, or even a hobbyist, if you're looking for the very best performance sounds from a super-stable keyboard, you'll find it with the Kurzweil PC3K8!

The One

This review is a long time coming. I bought this six months ago and let me share my story. I had the cash to afford any workstation on the market. I drilled down to the following three which I determined were industry best based off countless other reviews and awards: Yamaha Motif XF8, Korg New Kronos 88, and the Kurzweil PC3K8. I already owned the Motif XS8 and liked it. However I had my eye on this bad boy since Kurz announced in five years ago. I owned a Kurz digital piano back in the day and loved it. Needless to say like most Kurz products it's a preferred taste situation. You will either instantly love or hate their products for the most part. I obviously love them and for good reason. The PC3K8 beyond the XF8 and New Kronos mentioned has build quality that far exceeds those two in my mind. This thing is built like a battle tank. Meaning if you gig with it you have peace of mind. The build is apparent immediately when you touch this thing. The keys are in my opinion the best feel I've experienced. The funny thing is they are not the most realistic. I would accredit the Motif with having a more "life-like" keyboard. However that doesn't matter to me. This is a digital keyboard after all so the assumption is that the player will want action that is suited for playing multiple styles such as rock where you want more give and response. I'm by no means compelled to redundantly write about the sound or overall capabilities of the PC3K8. There has been so many reviews published it would be entirely moot. As a workstation the on-board sequencer is efficient and unlimited in performance. In closing I found this to be the workstation for me because it feels right. This is a top quality professional keyboard for true industry pros. It will do whatever you want it to do. I have mine running through an AudioBox 44VSL with Studio One 3 Pro. Everything is in perfect harmony. With Kore 64 I have an outrageous amount of samples and effects to add to any style I choose. Lately I've been big on ambient cinematic scores and this delivers in spades. If you're on the fence please waste no more time and buy this!

Just buy this and be amazed

I bought this to replace my 16 year old (never a problem) PC88mx. I shopped other brands. There are a lot of great boards out there. Not one of them even comes close.Stunningly realistic sound reproduction. An endless array of effects. The Hammonds are as good as my B. And then there's the K section. Whoa! It's built like an Abrams tank. You will spend some time with the tutorials on Kurzweil's site. Then the light bulb comes on and there you are. If you are truly a professional buy this and leave the toys for the kids.

Take it to the next level

I have a K2600XS and a K2661. I recently received my PC3K8 and am seriously blown away by this new generation of K's. Not to mention that I haven't yet had the time to explore the add-ons that came with this deal from Sweetwater, so I'm sure there is more to come. As a technically minded person, I am impressed with the SoundTower program editor/librarian. I pride myself as a cover artist being able to replicate sounds from the original recordings as opposed to simply sampling them. To me sampling is no challenge and I thrive on building sounds. In this arena, Kurzweil more than delivers. In a nutshell, the PC3 series compared to the K2x predecessors is much more organized, more user friendly and packs a ton of extra horsepower to deliver theater quality sounds from a single instrument. As usual, I would recommend this piece of gear to any serious keyboardist.

Kurzweil PC3K8

The sounds are fabulous. The flexibility and control options are almost limitless. Keyboard action is great. Build quality is excellent, solid. You will not be disappointed with this keyboard. It will be the last board you will ever need, (unless you need sampling capability). My favourite sounds are the pianos, EP's, organs and pads.

PC3K8 playability and sounds

I am going to be honest and give both my opinion on pros and cons. I do not give the new KZ a 5 because of several reasons. First for the CONS, playing really fast synth parts is not quite the same as a controller or normal synth keyboard only because of the lack of really fast response from the weighted keys. Also, the KB-3 leslie simulator has not really improved much (if at all) from the old K26xx series. It still sounds somewhat phony, very much like a vibrato/LFO vs. a true FM created doppler effect. There are several Leslie simulator fx boxes that do a much better job than the PK, so i would recommend picking one of those up and improve your sound. Another con is the ribbon controller is not included on-board, which rather sucks because the pluggable one just kinda gets in the way both from a placement perspective and the fact that you have the dang cable running over the face of your keyboard. I would have gladly exchanged a little more weight in a slightly bigger frame to accommodate the ribbon. With that said, lets move on to the PROS. First and foremost, its a back saver on this model vs the old K26 series. Perhaps close to half the weight so its much easier to carry around from gig to gig. Second, no skimping on any of the original programming features, and in fact they have expanded a bit. Plus there are many improvements to old sounds, addition of new sounds, expansion to user slots, and the KORE expander is quite nice. Programming itself is as easy as it has ever been in the past, and even more so and much more user friendly with the addition of the software. It does take a little time to get used to, but once understood, its a breeze. And the USB port is fantastic for importing sample, programs, setups, etc. Overall, the PC3K8 is a great board, although for the price I would have expected a little more in the "improvements department". Unless you really have a need to, or just want to have eye candy for the audience, you can leave all the other keyboards home and just bring one to a gig. For me, I prefer just the PC3K8, with my laptop along for good measure so I can really beef up the sounds with MainStage and/or Logic Pro using Arturua and Spectrasonics products. Sometimes even bringing a simple controller along to expand the use of more sounds needed for more complex material.Hope this was helpful to everyone.
