Nils‘ K1v now available as Mac/Linux VST & official approval by KAWAI!

Finally, after waiting several weeks, Kawai reported back to me that they have no issues with me developing a Kawai K1 emulation. This is great news for me personally as I was still concerned that Kawai could respond in a way that would bring me in trouble. But they did not! 👍 They even sent high quality Kawai logos that I’m allowed to integrate into the plugin, I’m impressed, big thanks to Kawai!

Furthermore, there are now Linux & Mac versions of the VST. For Linux, there are .deb and .rpm packages in both 32 bits and 64 bits. The Mac version requires a 64 bit OS, minimum version is OS X 10.9 Mavericks.

For Mac, an AU version will definitely come. LV2 for Linux, too! Stay tuned.

Special thanks to all donators and to all testers at the KvR forum, a lot of people helped making the plugin available for Linux & Mac by testing on their machines.

My Kawai K1m: What is broken? Help needed to repair

You may have read about my Kawai K1m in the development blog. Unfortunately, it is slightly broken and I thought, as there are so many people around still loving these old machines, that some of you could give a hint to repair it.

The issue is that the envelope attacks behave incorrectly. Short attack values are fine, but larger values cause the machine to end in complete silence.

With attack values larger than 36, the attack never finishes, decay is never reached and the sound is audible forever, no matter what the decay/sustain/release values are.

If the attack is even longer, starting with value of 50, the volume starts to decrease. The attack gets stuck so early that the voice keeps being very quiet. With a value of 69, the sound is not audible anymore at all. Below is a picture that shows attack values up to 69, where the voice becomes completely silent.

Attack values up to 69

Anyone knows what is wrong? What I already tried:

  • I added fresh solder to most ICs, including the CPU, the WaveROM (you might know) and the RAM chips
  • I measured the connections between the three tone generators and between tone generators and CPU & Wave ROM, they’re all fine
  • I upgraded the K1m firmware, I ordered a new chip with version 1.5, previously it had 1.3, no change
  • I contacted Kawai and asked for help, unfortunately they have no idea
  • I turned it off and on again 😎

My current assumption is that one of the Tone Generator chips is faulty and needs replacement. If there is anyone with another idea, that would be absolutely fantastic! 👍

Anyone with ideas? Thanks a lot in advance!

Nils‘ K1v: Demo Video by MOSS

Just in case you didn’t see it yet, I am so excited about what Jürgen Moßgraber aka MOSS did. He created a whole song with the K1v. Except for some FX, there are only K1v instances in his music track. When listening to it, it instantly reminds me of the 80s. Thank you very much Jürgen for doing this! 👍😊
