Free VST/VST3/AU effect with Computer Music – HY-FX CM

Regular readers of CM’s monthly Freeware News column will be familiar with indie software devs HY-Plugins, purveyors of quirky step sequencers, slicers and effects processors – and we’ve teamed up with them to bring you an unmissable plugin that’s guaranteed to spark creativity in the studio.

Operationally, HY-FX CM (VST/VST3/AU) couldn’t be easier to get your head around. First, choose one of the 22 high-quality processors from the main dropdown menu. Effects include five flavours of delay, four filter types, four modulation effects, pitch/frequency shifters, dynamics, distortion and reverb.

Things then get even more creative once you get those parameters wobbling with HY-FX CM’s LFO, Envelope Follower and Sample & Hold module. Modulation is assigned via an intuitive, colour-coded, drag-and-drop workflow: drop a source’s cross onto an empty mod slot (two available per parameter), then drag a collar around it to apply modulation. 

Once your modulation has been assigned, pop open a modulator’s edit window and precisely customise its speed, shape and more.

All of this action could be overwhelmingly confusing, but thankfully, HY-FX CM makes visualisation a priority: aside from handy colour-coding for the three modulators, all modulation signals are smoothly animated, and every tweak updates the modulator waveforms in real time.
