Emulation is good but it is emulating a bad synth. K1 / K4 is nothing interesting. There is about 5% of sounds I would really use. M1/T1 are superior to K1.

Yes, it's free but we have lot of similar free .SF2 sounds from same era already.

(Note: current version is 1.24, July, 2021.).

A minute and a half of envelope decay when set at 100%! This is teaching me stuff I never learned about my hardware K1r. Thank you nils! You have made me a happy composer. Donation is going to happen today. Cheers.

Runs perfectly in Digital Performer 10 under High Sierra in my aging 2011 MacBook Pro. It's the most processor-intensive plugin I run, and I need to bounce to disk to use it, but it's totally worth the effort, and it's a joy to listen to it.

In most cases I'm not a rompler fan. Best example: SQ8ROM...1GB sampled from an 0,6MB VSTi.

But this is different. It is the emulation of real hardware and it brings a big, big bunch of great, well recreated sounds in a top quality. A must have for Kawai fans.

Needed a replacement as my real K1 slowly stops functioning after almost 30 years, this is perfect! It loads all the sounds from my library (> 10.000) without any problem and sounds almost exactly like the original.

For being a free plugin alone, this deserves 5 stars. Instant late 80ies/early 90ies feeling. If you like LFO (the band), you will love this plugin.

I have a K1r mk1 in my rack next to me and the plugin fails to model one crucial ingredient of the original: the noise floor;).

Really well done, Nils! And may I add that the fact this exists not only for Windows but also as a Mac VST and AU and on top of that also works on Linux systems is seriously mind-blowing. Especially if you consider the short time span during which all these versions for different platforms came out.

I have earmarked some € to donate (and may I suggest you consider doing so as well?), especially for the AU version. If this was a commercial plugin, I would not hesitate to part with 50 or 60€ if I was making as much music today as I used to. Don't like Ro-land Cloud but like the D-50? Get this. Seriously, download this plugin if you like breathy, aliasing ROMplers as much as I do.

So far, I haven't tried to use the plugin as an editor for the hardware but I am really excited to so. Just the fact that an emulation is capable of doing so is so awesome (Dexed comes to mind).

Disclaimer: I'm not affiliated with the author of this software in any way. I'm simply blown away that somebody so talented and focused on getting stuff right (read Nils' blog about the development of this plugin, he's a man of dedication) would share the results of all his efforts with the world for free. And I do have a soft spot for quirky Kawai synths, now I can take one of them with me when I travel. I love this plugin.

Couldn't be more surprised or pleased. Been looking all over, but only limited samples were available. All the cards, all the controls... Fantastic and sounds just like the real deal (as far as I can remember). Raw. Sits in the mix fantastically. Has the look as well and can load and save both single patches and banks (.MID or .SYX). Yay Nils.

I can't believe it !!!!! I've owned a desktop version which I had bought in the late eighties/early nineties..

Just a few months ago I've sold it and regretted it instantly.. Now it's back.. For good...

I say it's back because it is a brilliant replica and I know what I'm talking about... I've had it for 30 or so years and know it inside out...

Thank you Nils .

Hi, .

this emulation is great, I love it! Thank you very much.

I spotted one problem with version 1.0.8 though: Omnibus Loop Samples seem not to be retriggered when playing new notes. Instead they seem to be looped internally for ever, though they are not audible. So when playing instruments with these samples they start somewhere in the middle of the sample, depending on the current position of the internal sample pointer. I am not sure if this is also true for the other looped samples as well.

You can hear that when playing the instrument 'SlaveLabor' (A1-01/EA8).;).

Edit: This is fixed in version 1.0.9.

Hi, .

I had a K1 in the past and I think this one is much less noisy than the hardware.

It's a very accurate recreation and I retrieve all the sounds I used with great pleasure.

Thank you.

Remark : I have a little bug I think when I clic on Edit on iA1-Voice preset, I get a green button on source 2 and when I clic on source 1 the source 2 stays green so both sources are green.

This is on Windows 10 / Reaper 6.

Wow, this really is a blast from the past! I've just spent the last two hours playing with this and they were two of the fastest hours I've experienced in a long time. This really is an outstanding offering, one I think will really stand the test of time and build up and army of followers/users for a long time to come.

The sounds /presets are amazingly accurate and clear, while the UI is intuitive and easy to use. The interface looks a little dated, but I guess it could hardly be anything else when you remember what it is we're dealing with here. Still, it would be a nice touch to have skins for this at some future point, as well as an FX page under the Mode section. tucked away out of sight, so as not to take from the vintage look that greats you when you load up this little gem.

Still, even as it is, it's a great realization of a real classic and kudos is well and truly deserved for all the time and effort that went into producing this. Thanks Nils..very much appreciated.

Great emulation, sounds just like the hardware I have. I would like this plugin to be scaled down some, as it seems quite huge on the screen.

Quick note, after playing with it for a short period.

Well done!

It's got that obvious late-80s digital with analog circuits sound.
The interface seems clear and bonus marks for making it scalable (something I very much look for in a plugin these days, as I have a 4k monitor and 50+ year-old eyes.)
I never had the pleasure of owning a K1 back in the day, but I certainly spent some energy thinking about them.
Now: back to playing.

Hallo, .

konnte jetzt in 64-bit Nils K1v antesten. für lau ein irres Teil.

In 32-bit hat mein Virenscanner 360° einen Trojaner vermutet.

Scheint aber ein Fehlalarm zu sein.

Habe mich in meine Zeit versetzt gefühlt, in der ich mit dem

Kawai POP Synth Module PHm auf der Bühne gestanden haben.

Dieses hatte sehr ähnliche Klänge. Der Synth ist schön übersichtlich

gestaltet, die Sounds sind so, wie man sie für ein Vorbild der 80er erwarten

kann, sogar besser. Insgesamt ein Highlight der Kostenfreien VST.

Vielen lieben Dank dafür.

Fantastic job Nils.

You really captured the gritty nature of the k1. I own the k3m but I have been looking at k1 rack versions though I may not have to now because of this gem. Good on you and your talents.

1.0.1, with some presets emit strange background sound, hope fixed...

Could you send me a recording of that background noise? At what sampling rate do you use it in your host?

3 July 2020 at 3:35pm

REAPER and FL Studio 9 (all 32-bit) under Windows 7, 64-bit.

It's like a "tick tock" sound that affect the sound, not in first sight but it's audible.

Tried now with version 1.0.2, same problem.

I don't know how send a file here but by the way sorry, hope you'll resolve or probably it's a simulation of the cheap onboard converters of the original hardware? i can't recognize.

What a great project. Like a time machine transporting my ears instantly back to the period, thank you.

5 July 2020 at 5:24pm

What's the name of that Wavestation-like patch that loops a couple of strings & aaahhh PCM samples? The preset that was famously used by LFO on their seminal self-titled techno hit "LFO". Would grab this one just to be able to play with that preset. A friend of mine got this as his first synth back in 89.

6 July 2020 at 10:19am

On the Nils K1v the preset is 'iC8 Arrangement' I found it by resetting to the factory settings............... LFO your heart out :)

Great project, great sound. Kudos!!.

How do I install it in Cubase 10 Pro, I have placed K1v_x64.dll in various VST plugins folders and each time run Cubase and plugin manager but it seems to be invisible to them, I have even placed in the same folder as my Sylenth1 and no go. Any assistance would be appreciated.

OK, so when I installed the 32-bit version and Jbridged it, it shows up.

Just grabbed this. My studio rebuild is not for another few weeks but will try this out then! I still have my K1-r but this just looked too cool to pass up and realtime JOYSTICK control ala Vector movement? Yes please.

1.0.6 - a very loud short clicks when playing in Renoise 3.1 in some presets. They aren't in Renoise 3.2.1. Empirically, I was found that the problem in the delay of the envelope. As soon as you remove the delay, a clicks disappear immediately.

Also, occasionally K1v misses some notes (in all Renoise versions, not only in 3.1), but I did not find any regularity. But this happens VERY rarely, so I have no special problems with this.

Version 1.0.4. Thank you SO much for this wonderful VST. I have a very old K1m with a lot of custom patches, and was able to transfer all of them in via sysex without any issues. Also very happy to report that it works in Linux using the Carla Windows bridges. The only issue when running (in Linux) is that none of text displays on the various buttons, or in the middle screen where the available patches are shown. I am assuming this is simply a WINE font issue? Does anyone know what font may be missing?
