Seriously, if you ever find a Kawai K4 sitting on a shelf for a decent price, I wouldn’t hesitate one second to pick it up. The effects on the Kawai K4 absolutely make a world of difference to the sound and edginess of the K4. In addition, there is an effect processor in the Kawai K4 synth version which is actually quite nice. Along with the Kawai K4 I was able to snag a DC-16 Memory Card which was a huge bonus because I’ve heard these are near impossible to find. It all integrates seamlessly even with the Kawai K4r. MIDI implementation is exceptional and with my Kawai Q8 sequencer it should be a blast to program some good drums and sequences. You really need to have easy access to layer, split, and program the velocity switching on the fly so that you can really get the most out of this beast. The keyboard version is just so much fun to play live and peform with. Without a doubt, I recommend the Kawai K4 over the K4r for one simple reason. Thus I could care less if it’s digital in that it simply rocks my socks off! This leads me to believe that with effective programming the Kawai K4 can improve even more which is hard to imagine because I already love it. It is a “VERY” digital sounding machine, BUT it does have a very warm sound to it and with some patches it sounds very analog”ish” to me. I did hear that only a limited number of them were made, so perhaps that is one reason why. I simply can’t believe nobody else either has or promotes this synth. Lots of reviews cite the Kawai K4 as a very good synth for Industrial, Synthpop, DnB, and Hardcore/Breakbeat/Chemical synth style music. It was so much fun to play and sonically, it beats the crap off a lot of good gear I have. It’s a digital powerhouse monster and frankly I couldn’t stop playing with it when I was testing it in the shop.

The Kawai K4 is a 61 key with attack, release velocity, and aftertouch pressure.
KAWAI K4 PATCH EDITOR PLUS
Plus there is velocity switching, so you can have different sounds play depending on how hard or soft you press the keys. This makes moving from one patch to another seamless. There is also a “link” function which allows you to program a queue and change patches on the fly during a performance. In addition, you can have up to 8 different tone layers. The Kawai K4 can split up to 8 different sections at once. For $50 bucks, I couldn’t pass up this beauty.

I already have a Kawai K4r and that is basically the same thing as the keyboard version, however, the synth version has some very good features that are had to pass up. Today I found a used Kawai K4 in the local used music shop and I must say it absolutely ROCKS! Oh my, what a gem.
