DSP functions
What each block does
The functions a layer's blocks hold: low and high passes, resonance and Drive, bands, notches and all passes, EQ, shapers and distortion, oscillators, and the ones the factory uses most.
Each place of an ALG holds a DSP function: a filter, an EQ, a shaper, a gain or an oscillator. Each one does something you can see: a filter's response, a shaper's curve, an oscillator's wave.
Seven lessons: low pass and high pass, resonance and Drive, band pass, notch and all pass, EQ, shapers and distortion, oscillators, and the factory's functions. Each plays the function itself, with the factory's values.
From a filter's slope to the factory's favourites.
Each lesson plays functions with the values factory layers give them: see the response or the curve, move the values, and hear it.
A low pass lets the partials below its cutoff through and turns down the ones above; a high pass does the opposite.
8,819 layersLESSON 2Resonance and DriveFiltersThe 2-pole and 4-pole filters have a resonance: dB of boost (or cut) right at the cutoff.
120 resonant settingsLESSON 3Band pass, notch and all passFiltersA band pass keeps a band around its frequency and turns down both sides; a notch takes that band out and keeps the rest.
594 layersLESSON 4EQ: mids, shelves and trebleEQThe EQs leave the sound as it is and lift or lower one part of it.
3,793 layersLESSON 5Shapers and distortionNonlinearA shaper bends the wave itself: each input level becomes another output level, the curve on the left.
1,177 layersLESSON 6OscillatorsOscillatorsThe oscillators make their own wave at the note's pitch: a SINE (one partial), a SAW (all of them), a SQUARE (the odd ones), a PWM whose width moves the partials, a SHAPED SAW that turns from saw to sine, a SUPER SAW of two detuned saws, NOISE, and the FM operators that bend a sine with what comes in.
1,570 layersLESSON 7The factory's functionsGalleryOf the 59 functions, the factory programs lean on a handful: the 2POLE LOWPASS above all, then LOPASS, TREBLE, HIPASS, the two mid EQs and the shelves.
