Scream and Scream Again by Propellerhead Software
There’s a new breed of Reason FX units in town, and they’re not to be messed with. The most lethal weapon of them all is the Scream 4 Sound Destruction Unit. Sure, it can play nice, gently warming up your sounds with a smooth tape saturation algorithm – but underneath the innocent facade lurks an audio assassin, a mad mangler that will tear your sounds to shreds and leave no one alive to tell the tale. Dare you read on?
Scream 4 Waveforms by Peff
This is a set of scope images taken during an analysis of Reason’s Scream 4 Sound Destruction Unit. Original Signals – Sawtooth wave generated by a Thor Polysonic Synth in Reason 4.0.
Scream Tape Algorithm Phase Inversion by Off White Noise
Peff points out here that the Scream4 ‘tape’ algorithm has an effect of inverting the output waveform at lower frequencies. This can have the effect of canceling with the original signal if mixed back (e.g. as a Send Effect). He posts a couple of solutions and a good example that illustrates this “feature”.
Patches and ReFills
Noise! by Suzy Wong
Noise! is a powerful distortion based multi-effect refill for your Reason Rack. Crush, spank, grind and mangle your productions with the ultimate in destroy FX. Noise! utilizes combined FX chains to deliver extreme audio warping. A concept device featuring filtering, bit crushing, overdrive, spring verb, flanging and compression, carefully concocted to conjure harmonic images from the darkest depths
Multi-Band Distortion Unit by Resonant Filter
I started playing around with different multi-band effects ideas and came up with this distortion effect I’m dubbing “Sonic Warfare”. It has 3 bands, which are controlled with the first two Rotaries (Rotary 1 is the Low Band, Rotary 2 split the High and Mid Bands.) You can choose the Damage type for the Mid and High bands with Rotary 3 and 4.
Thee Gristleizer by Resonant Filter
Thee Gristleizer is an effects box built by Chris Carter of Throbbing Gristle fame. The device was based on a kit and schematic in ‘Practical Electronic’ by Roy Gwinn. Recently a company based out of Asheville, North Carolina, have started making an authorized version of Thee Gristleizer and Throbbing Gristle used the new version on their recent reunion tour. However, if like me, this recession hasn’t been so kind to you, and dropping $375 on an effects device isn’t currently feasible, maybe I can interest you in my version built for Propellerhead’s Reason 4.
Skream by Teknolab
Skream is based on the Scream device. It’s basically the same but the P1 and P2 values can be auto-adapted (reduced or increased) by the volume of the incoming audio. The volume is read by a compression device that determines the compression amount. This amount is the CV-signal used to auto-adapt the P1/P2 values.
