ConcreteFX releases Rock


ConcreteFX have released Rock, a free Windows VSTi "distortion" synth - good for creating nasty basses, leads, distorted pads, sequences and weird sounds.

Rock uses two oscillators and filters, each with lots of shaping and combining options to create different sounds, including being able to create your own waves (hundreds of different additive waves are included with Rock).

All the synth parameters are controllable using a mod matrix which can using envelopes, LFOs, step sequencers and MIDI controls as mod sources.

Six effects (Compressor, Distortion, Low-Fi, EQ, Delay, Reverb), the order of which you can change, with FX feedback.

Rock is fully skinable and comes with 2 sets of skins, as well a full manual and 128 presets.
