Interesting synth, but occasionally loses parameter control when automation created (in FL)

Im waiting for a guy to do a emulation of a Yamaha DJX. It was a department store keyboard, I bought one and it was a blast. All the electro dudes would go apeshit if a developer made a vst emu. That was a honey for electronica and techno.

Had a Kawia Keyboard in early 90s. Was rather cool but very incapable of much. This is really cool, I remember the sound and this on point, but needs some more development. Might have something here if worked on bugs.

Brilliant synth. High CPU when playing chords but sounds are so good without even editing!

It Kills the DAW (Cakewalk) every time I try to create a track using this Plugin

I had/have a K1 m and love/d it especially for those tiny malfunction blips the engine created in extreme high or low pitches. And even those effects are emulated. Great VST. I dumped all my edited sounds from my hardware K1 via SysEx to import it into the VST and it works fantastic.

The more I use it the more I like it. Occasional crashes tho. But not many.

Excellent recreation of the K1v. There is a lods of patches, a lot of them with quite some nostalgia value, others are quite original, and some really good. Edit is easy and the VST user interface is great. I have no big bugs but a small one that is more of a minor annoyance (I use FL Studio in 32 bit on Win 7). This minor annoyance : when I put the release of one the four sounds on 100% the sound will not stop even when I put the release lower, or either if I clic on this vst "Sources Mute", or either when I press stop twice on the transport of my DAW (it usually kill everithing, even reverb remainers)... the only ways to stop this non stopping sound is to change the patch or reload the plugin.

I noticed this as well in FL Studio. The ADSR envelope doesn't seem to work properly unfortunately.

Tried this, in a savihost. Had immediate breakdowns when I went into edit mode. Don't know if it's because of aliasing or what. I was changing waves, trying to use the pressure=frequency, but alas must be channel pressure that works, because poly pressure did not. Pretty cool little synth though. I had fun.

Is there any way to fix the glitch that forces me to restart my DAW everytime?

Whow, i realy love it! This was my first Synthesizer in the 90ies. Reminds me of the time with my first band! Really accurate, it seems to me as if it sounds better than the original, where is the noise, did you supress it? Only thing I miss is the multi mode to combine 4 singles or didn't I get that?

Really unstable synthesizer, sometimes it cuts out all of the audio then I have to close then reopen my DAW just so I can get it to work again. It does this frequently.

Wow ! This thing is a MASTERPIECE ! I still haven't tried all the sound after an hour of browsing ! Perfectly stable under Win10, Cubase 10.5. OK, the sounds feel retro as Hell, some even seem to come from your Super Nes. But some are still very usable and the quality relies on the original hardware anyway. Feels like something between SQ8L and Korg M1 VSTs. Thank you so much for making this synth, you're a true boss !

Works perfect in FL Studio 12.4 / windows 8.1 An excellent sounding synth, re sizeable GUI, low on CPU. 10/10 to the dev.

Crashes cubase (10.5)win 10, everytime you change patches.

I just loved it so much, its so dynamic and so easy to make presets. But sometimes it emmits a fast and loud pluck that makes me jumpscare, i dont know if is the synth, my host, or my computer that is causing this problem... I tried to optimize my cpu performance but didnt solved too much...

Updated version: the loud pluck has been fixed before I noticed that, thank you so much... ;)

Youtube has many video's of the hardware version, since this is a complete emulation of the K-1.

Finally!!! Another long-awaited synth! Very good and superb! Sounds like real machine. But... how to save (write) my own preset (edited factory preset)?

Very cool lovely synth! Thanks! Unfortunately, there are trouble with fonts in buttons in Reaper x64 (win version, linux + wine). But it's not author's bug, maybe some fonts not installed.

Got the same issues. Nevertheless a great sounding vst.

Grandios. Ich fühle mich in die 80er zurückversetzt. Danach hab ich immer gesucht. In Reaper mit Wine unter Linux gibt es ein paar graphische oder textbedingte Schwierigkeiten. Die Beschriftung einiger Schalter sowie die Presetliste sind frontseitig nicht vorhanden. Lediglich ein großer, grauer Klotz. Trotzdem gefühlt 10 von 5 Sterne alleine für den authentischen Klang!!! Vielen Dank fürs Programmieren.

Unstable in fl studio! but when I enabled use fixed sized buffers it seems ok apart from the gui size keep defaulting. But for free worth a try

I think it's the closest thing to a D50 that you can get for free ! It's unstable in Cubase 7.5 but works perfectly with Ableton and Mulab.

Interesting plugin but it doesn't work well in FL STUDIO 20. There are problems with the sound due to peaks that interrupt it. The plugin is still unstable.
