kHs ONE was not designed to be a fat analog beast with a massive warm sound. That just happened anyway. Now it's finally available for your reason rack!

Product details

Whether you want a thumping bass, squelching lead or a smooth pad, kHs ONE stands ready to serve! But don't worry, it won't get sad if you just throw it in for a simple sine sub. Not visibly, at least.

With highly morphable oscillators and a vast array of modulation options all fit into an easy to understand GUI, kHs ONE is the perfect synth for both users new to subtractive synthesis as well as hardened veterans.

Just look at all these bullet points:

  • 2 Main oscillators (saw/square/noise)
  • Sub oscillator
  • 2 multi mode filters (including vowel filter)
  • Per voice wave shaper
  • 2 LFOs
  • 3 Envelopes (amp/filter/mod)
  • 8 voice unison
  • 24 voice polyphony
  • Env/LFO legato on/off
  • Portamento/Glide
  • Onboard FX: Chorus, Delay, Equalizer and Limiter

"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 UK

"kHs ONE is amazingly thick sounding, and is quickly becoming my fav new synth. Swedish engineering yet again!" - James Wiltshire (Freemasons)
