Kairatune is a free software synthesizer plug-in designed for electronic music production.

If you are looking for an all around synthesizer then you better look elsewhere, but if you are looking for synth that will work great for electronic music then this might just be for you.

Kairatune's main objective is to provide electronic bass, lead and SFX sounds, all within a reasonable amount of time. Having been designed for musicians instead of for engineers. So instead of dealing with maths which at times prevent potential synth users from trying the instrument, Kairatune's workflow is designed so that you will be dealing with familiar concepts of beat, notes, intervals and pitch.

Features:

• One Multi Oscillator
• Pitch is controlled by traditional vibrato, by a trill modulator and by a shared LFO source
• Spread functionality via high frequency damping and delay
• Make amplitude modulations without audible aliasing
• Features a resonant lowpass and highpass filter
• Includes two EQ units, a six stage phaser and delay units.

Here is a video sample of Kairatune at work:
