Pictured are three modules from Mutable Instruments.<\/a><\/p>\n

Peaks<\/h4>\n

Peaks<\/a> is a multi-function digital module that’s relatively easy to understand.<\/p>\n

Peaks provides 4 different functions in a small 8-HP package. Their common point? They are all about generating an audio or CV signal in response to a trigger, and are all focused on rhythmic works.<\/p>\n

Peaks is a dual-channel module \u2013 making it very useful for duophonic patches or for controlling\/synthesizing the kick\/snare rhythmic backbone of a patch.<\/p><\/blockquote>\n

It is a manually controlled dual envelope generator and LFO.\u00a0 My favorite feature is the LFO, because of the variety of wave shapes: wave folded sine, variable slope triangle, PWM square, stepped triangle and sampled\/interpolated noise.<\/p>\n

Here’s a demo recording of a Peaks LFO in sampled\/interpolated noise mode controlling the frequency of the Sprott filter.<\/p>\nhttps:\/\/pugix.com\/synth\/wp-content\/uploads\/2016\/02\/peaks-chaos-lfo-mods-sprott.mp3<\/a><\/audio>\n

 <\/p>\n

Peaks also has a drum and hi hat synthesizer.\u00a0 Now I can make beats!<\/p>\nhttps:\/\/pugix.com\/synth\/wp-content\/uploads\/2016\/02\/peaks-drums.mp3<\/a><\/audio>\n

Shades<\/h4>\n

Shades<\/a> is a simple, very nicely designed multi-mixer, that reminds me of the Oakley Multi-Mix.\u00a0 Mutable Instruments open-sources their hardware and software!\u00a0 You can download the Shades schematic, which I did.\u00a0 The cascading scheme is different from the Oakley, in that the top section cascades to the second, and second to third, instead of all mixing to the third.\u00a0 My favorite feature is the unipolar\/bipolar switch, that I always wished the Oakley had.<\/p>\n

Warps<\/h4>\n

Warps<\/a> is the modulator I selected to be one of the main components of my Wave Mangling System.\u00a0 It has many nice features.<\/p>\n

Warps blends and combines two audio signals through a variety of cross-modulation algorithms. Most of these sonic transformations make the distinction between a carrier signal and a modulator signal: the former will be filtered or modulated to acquire some of the characteristics of the latter. Warps also includes a digital audio-rate oscillator which can replace the external carrier signal.<\/p><\/blockquote>\n

It’s easier to understand by looking at the block diagram.\u00a0 Essentially, Warps modulates two audio signals together, using a selection of algorithms: cross-fade, cross-folding, digital model of analog diode ring-modulation, digital ring-modulation, bit-wise XOR modulation, octaver\/comparator, 20-band vocoder.<\/p>\n

An internal VCO can replace the first input and can be independently accessed.<\/p>\n

The input levels of both signals have a VCA.\u00a0 Within each algorithm there is variable ‘timbre’.\u00a0 The algorithms fade from one to another!\u00a0 Algorithm and timbre selection are voltage-controllable.\u00a0 I made some notes while checking it out:<\/p>\n
