Karnage
Karnage is a free software synthesizer developed by Kriminal. Available format(s): VST for Windows.
Karnage is the result of a collaboration between Krakli Software and Kriminal.
Features:
- Two oscillators with width (fatness setting) and wave-shape control, a sub oscillator/white noise oscillator mixable with a level control.
- 24db/12db Filter modulated by a dedicated envelope, velocity, and up to 2 LFOs.
- A dedicated ring modulation section that can use keyboard tracking, velocity, envelope, and up to 2 LFOs for modulation of Ring Freq.
- Amp section where amplitude can be modulated by velocity and a dedicated envelope – with it’s own built-in compressor. Plus Velocity control of Amp and Filter ADSR Decay.
- A performance section that has Poly-Mono switch, Glide, Glissando and retrigger switches with Time control on the glide. Glide can be routed to OSC1, OSC2 or Both.
- A dedicated distortion unit which uses pre and post filtering (it is this which can give Karnage its unique sound). The modulation (LFO1 or LFO2) is of the pre-post cutoff but the types of filters are set by the shape control so all sorts of effects are possible from a phasing type of modulation to a vocally formant shifting effect, (talk-box effect).
- Two LFOs, whose rate is controlled manually or by host tempo. Destinations are Filter, Ring Modulation and Distortion for both LFOs and you can apply each LFO to more than one destination at once. The LFOs also have MIDI Trigger On/Off (Gate).
- Full set of 128 presets by a variety of respected patch-makers.

Karlinger
Karlinger is a free software synthesizer developed by Water Resist Synths. Available format(s): VST for Windows.
Karlinger is a 16 step multi-panel SoundFont sequencer. The sound modulation and sequencing is done through four independent panels (it consists of two SoundFont panels, a pitch sequencer panel and a filter sequencer panel). The synth panels contain SoundFont patch/bank selectors.
Each sequencer has the same controllers; with them you can define:
- The starting and ending points.
- The direction.
- The tempo of a sequence.

Kamioooka
Kamioooka is a free software synthesizer developed by g200kg. Available format(s): VST for Windows.
Kamioooka is a polyphonic Full-Modular synthesizer with patch cable system. You can freely combine modules and make patches. 10 module slots and 7 types of modules (VCO/VCF/VCA/ADSR/LFO/MISC/SEQ) are available.
Available modules:
- VCO : Oscillator, with PWM/FM/Sync functions.
- VCF : HPF/BPF/LPF filter.
- VCA : Amplifier with modulation input.
- ADSR : Two ADSR Envelope Generator.
- LFO : Two LFO with tempo sync mode.
- MISC : Ring modulator/Noise Generator/Sample&Hold/Inverter.
- SEQ : 8 Step Mini sequencer.
ATTENTION
In v1.0.2, the Unique-ID of the 64-bit version is changed for 32/64 patch compatibility. Old patch (.fxp/.fxb) made with 1.0.0/1.0.1(64-bit) may not be loadable (If you want to use anyway, VSTHost/SAVIHost can load forcibly and can be convert to new ID by exporting).{See video at top of page}

Kamilla
Kamilla is a free software synthesizer developed by Scoofster. Available format(s): VST for Windows.
Kamilla is a simple two-oscillator subtractive synth with a special filter design and various modulation possibilities. The filter design offers three multi-mode linkable filters, which make it possible to create a wide range of sounds from fat 36dB basses to formant-like vowel sounds.
Features:
- Two syncable oscillators with 7 waveforms, FM and ring modulation.
- Three linked multi-mode filters with keyboard tracking, parallel and serial filter routing.
- User envelope.
- LFO with note on synchronization and Sample&Hold function.

Kairatune
Kairatune is a free software synthesizer developed by Futucraft. Available format(s): VST, Audio Unit for Windows, macOS.
Kairatune is a monophonic virtual instrument designed to produce crisp and tight electric sounds. Kairatune is engineered for the demanding producer who needs to push the sound to extremes without compromising audio quality.
Kairatune offers fast and intuitive sound design workflow. The user interface is designed for a musician rather than an engineer and is based on the concept of pitch and tempo in contrast to frequency and time. Kairatune lets you travel in the world of beats, notes and intervals instead of the logarithmic mathematics of frequencies and the rarely useful absolute time.
Kairatune is not your all-in-one synthesizer. It’s designed and engineered to be as powerful and versatile as possible in its target role as your source for tight bass, unique lead and shiny SFX sounds. At the same time it makes all the effort to be simple enough to use, enabling you to add your personal touch and flavor to the sound and seek for the perfect fit to your mixing preferences.
The generator section has just one multi-oscillator. The basic waveform generator is very simple adjustable mix of sawtooth and square wave. The multi-oscillator generates five waveforms whose relative pitch, phase and amplitude may be configured and modulated enabling a rich set of tones. The multi-oscillator uses quite unusual technique that generates a single fundamental signal independently of the (multiple) overtones, preventing the beating effect that arises where several oscillators are output in slightly detuned unison, yet preserving the full and fat sound on the overtone spectrum. The method enables building very rich and vivid sounds on a perfectly solid bottom and is especially useful in creating tight bass and low register lead sounds.
Key features:
- Multi-oscillator sound generator, virtually a single oscillator with the sound of five.
- Independent fundamental generator prevents beating at the bottom while enabling full and vivid treble.
- Tempo synced envelopes and modulators for rhythmic action.
- Advanced stereo image and spatial modulation.
- HPF and BPF delay units, phaser, EQ.
- All parameters accessible at once on a single panel.
- MIDI learn function.
