"kHs ONE is amazingly thick sounding, and is quickly becoming my fav new synth. Swedish engineering yet again!"
. Dance Music Producers & Remixers (Beyonce, Fat Boy Slim, Luther Vandross, Jamiroquai, Kylie Minogue, Solange, Moby, Eric Prydz, Whitney Huston, Eurythmics, Rihanna, George Michael)
"Loving this synth, does a very nice impression of my beloved Juno 60. Can we have a whole Roland 'sound a like' sound bank please?"
. - Vern, One half of UK Production Duo, Stretch & Reflekt.
"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."

kHs ONE was not designed to be a fat analog beast with a massive warm sound. That just happened anyway.

We have put a lot of time and effort into making oscillators and filters of the highest quality which gives kHs ONE a pleasantly warm and analog sound.

Working with professional musicians and producers throughout the development process, we have made sure that the sound meets their high standards.
