Artist and developer DJ Swivel released Knocktonal – a plug-in that removes harsh resonances from audio signals. Unlike competing plug-ins (such as Reso, Smooth Operator, Soothe2 and so on) it also lets you add them back! When this is applied creatively, it can make for some interesting and unusual sounds. Being made with DJs in mind, Knocktonal is also MIDI-controlled. There’s cool stuff to find here, let’s dig in…


DJ Swivel Knocktonal – master the resonance

A plug-in like Knocktonal by DJ Swivel is a versatile plug-in for mixing, mastering, and sound design. You can use the subtractive EQ section to remove nasty resonances quickly and intuitively. All you have to do is establish the base frequency and graphically place the equalizer there using drag and drop. Up to 30 “overtone resonances” can be optionally considered.

Going a step further than most, Knocktonal’s Resonance EQ section lets you add resonances instead of squish them! In other words, you get to add tone to sounds that have no inherent pitch of their own – such as field recordings. The exciting part is that you can control the resonances (and their overtones) via MIDI, pitch sounds and play melodies or fit them in harmonies. What sorcery is this?!

At the end of the signal chain, there are a switchable limiter and an output volume control. All in all, Knocktonal presents an interesting concept – squash resonances or harmonize all the sounds in your track. Nifty!
