The easiest true side-chaining solution available

SideKick5 makes side-chaining very easy in your VST and AudioUnit DAW. Side-chaining is a usefull tool for musicians, producers, video editors and in radio broadcasting.

SideKick has helped many audio engineers by saving time while improving their mixes. Each SideKick5 you add in your mixer gets a number (1 to 16). And sends the audio it receives to all other SideKick5s in your mixer. This is done automatically through 16 stereo virtual buses.

Just select the virtual bus number of any SideKick5 you have put in your mixer to start side-chaining.

In popular music side-chaining is often referred to and used as a 'pumping' effect. In most of these cases the side-chain has been setup to listen to the kick or percussion, and then 'ducks' the volume of synthesizers and bass instruments.

Voice overs
In other media like video, films and radio, side-chaining is often used to attenuate the sound of voice overs. The side-chain will be setup to detect the voice and then lowers the volume of other audio sources like music.

With a traditional de-esser the side-chain only listens to a frequency range within 6 to 9 khz of the same source. Which reduces high frequencies of speech that tend to overdrive the audio on media like FM radio. By using the notch filter on the side-chain SideKick5 can be used to select a spectral focus within a certain frequency range to achieve this effect.

SideKick5 is made with native C++ and is built up from 10 years of experience ever since the first version of SideKick back in 2003. To give you the most easy and enjoyable side-chaining experience. This 5th generation of SideKick5 has completely been rewritten to improve compatibility, performance and usability. Check it out yourself; download it now and run a free trial !
