Kawai K1-II


The KAWAI K1-II digital multidimensional synthesizer has a wave based glistening warm digital sound compared to most of the competition in its class, (like the Roland D-50 or Yamaha DX-7). Using additive synthesis and samples combined in 4-oscillators with modulation can yield amazing sounds but, when you stack them multidimensionally with various pan, transpositioning, zoning, and velocity switching parameters, (think Wavestation joystick vectors),  the results are breathtaking; lush pads, strong leads, gripping sound effects, and bouncing stereo images to name a few.

Kawai K1-II System Exclusive set up instructions

Make sure that your Kawai K1-II is properly hooked up to your PC’s MIDI ports and can send and receive system exclusive messages. On your K1-II control panel make the following parameter changes:

  • Press the blue SYSTEM button and then press the blue -NO +YES buttons until the K1 LCD display reads:



  • Now press the blue SYSTEM button once more. The display should read:


RCV CH = 1

  • Make sure that the K1 is set to receive in channel 1 to receive the Sound banks.

If you are unsure about changing the above settings, please consult the Kawai K1-II owner’s manual which is included

* Please note that the included Kawai Factory RAM card library included has been divided into Volumes I and II meaning: Volume I is the actual Kawai RAM cards owned by Michael Lyon, and has been tested and verified working. Volume II was downloaded from Kawai’s International Website, and not tested or verified. Volume I and II could contain duplicate sounds, but I decided to include it within this package for your benefit just in case there were a difference.

  1. Thank you for the patches; I have a K1m, and have been considering purchasing a K1 II. These patches and documentation should provide many insights into the K1 series synthesizers.

    Thanks Again,

    Mike Akers

  2. Thanks for the information package and backups to the old patches. Interested in getting the new patches installed as well.
    The K1-II has kept its place even with the new Arturia MiniBrute in hands.
    I appreciate you keeping the legacy alive.

  3. Hello, can someone please walk me thru, how to send these new patches from my PC (I currently have Anvil Studio) to my Kawai K1 II? I’ve been trying to send these patches to my synth since New Years!

    1. I researched the Manual for Anvil Studio, and you can record, but not send System Exclusive Data; the format used to transfer sound data, (unless I missed something). Here: http://www.anvilstudio.com/usersGuide.pdf . I would suggest MIDI-OX: http://www.midiox.com/?http://www.midiox.com/moxdown.htm . Download and install MIDI-OX and follow this: https://kawaik1.wordpress.com/2016/04/03/how-to-send-sysex-data-to-the-kawai-k1/ . That should do the trick 😉

  4. Wow! After one year from the discovery of your UltraProteus pack, here is another one for another one of my synths! 😉

    Thanks a lot for your brilliant work!

  5. Thank you so much for making you your K1 patches available. Looking forward to playing them soon with my K1r II.
    (I also have the K4)

  6. Hello michael, I would very much like to use your patches for my kawai k1 II which I acquired recently, and which I fell in love with as soon as I touch it. Thank you so much. A big greeting.

    1. Hi Ivan, Yes the patches I have available will work on a Kawai K1, except for the effects section of the patch data, which is only available in the K1 II. :)

    1. Just WOW! These sounds breathe a lot of fresh air into my already dusty K1! VERY useful patches. Many thanks again for providing those!

      1. Your very welcome Florian, and everyone for your kind words. I used an Atari 1040 ST and the Kawai K1-VDS sound editor to make those. I am sincerely happy you like them :)

  7. Thank you for offering new life into these still very unique machines! Very much looking forward using these in my latest work.


  8. Hello and thank you for making this and managing this page!
    Very much looking forward to being able to use these.
