"The sound is indeed excellent and the price is certainly right. If you're looking to fill out your bass and lead sections with some authentic analogue oomph, this'll do the trick nicely."

- Computer Music

"kHs ONE is amazingly thick sounding, and is quickly becoming my fav new synth. Swedish engineering yet again!"

- James Wiltshire - Freemasons.

This is an updated review(version 1.011)

So, a new synth, which does not do any new magic, no new inventions or innovativeness, just a new synth, with high quality. I took a quick peek on it and thought it look like a synthmaker "save as plugin" kind of thing, but they don't say it is, so it must not be.

Lets be constructive, It's a cool synth, it's very analog in its sound, which in my opinion is great, because not many synth in this price range has that ability (i got this with the start up 60% discount though). It's more than great for electro/techno/trance/dance kind of sounds and of course vintage 80'ish synth sounds. It contains all the essential stuff like LFO, ADSR, Filters, and they are easy to route around.

3 OSC thay say, but the 3rd is "just" a sub with few options which is a shame, all in all the OSC section is a bit lacking, as it would be nice to be able to choose between more waveforms, even though you can shape the SAW and SQUARE. I also miss a noise osc, wonder why they didn't tag this great feature along. Again it really only does contain all the essential stuff you would expect (or almost), and nothing more.

The unison is cool, up to 8 voices with detune and spread, and it really works well, it can really bring spark to doll sounds, especially after the 1.011 update.

The effects section contains a shaper, a chorus and a delay unit, very useful and easy to use, they are not surprising you, but effective for the every day usage.

The presets take the synth around and showcases it very nicely, theres not a lot presets, but the ones thats present are cool and usable for many genres.

Computer wise it's on the average of CPU heating, the update toke care of small issues, and is running smooth now. When you hear the quality and compare it to the CPU usage, the quality is in favor.

It does not need any documentation or manuals if you have used this kind of synth before, but they have a forum if you have trouble with it.

So, a new synth yeah, ONE great new synth from a new team on the scene. It does not beat the other VA's on the market, but it sure does a great job anyway, as the quality is as good as it can be, for the sounds it can produce. Tags for this synth most be words like "Quality" and "Easy", because thats exactly what it is.

Looking forward to more updates for this little monster.Read more
