Modules and effects

All 50 modules, with their inputs, outputs and controls. Effects work as modules in a patch and as inserts in the mixer.

Sources 8 modules

Make sound: oscillators, noise, samples and drums.

OscillatorSources · one per voice

A tone in four waveforms, with pulse width, glide and frequency modulation.

Patch a Note cable from a Keyboard or sequencer and it plays those notes; without one it holds Freq. Width changes the shape of the square wave (50% is a true square, narrower is thinner and nasal). Pitch bends by up to Pitch amt cents (connect an LFO for vibrato); FM adds another signal to the frequency, by up to FM amt Hz, for bell and metal tones. Unison stacks 3, 5 or 7 copies detuned by up to Spread cents and spread across the stereo field: the wide, shimmering saw sound of big synth pads and leads.

NoiseSources

White, pink or brown noise.

White noise has equal energy at every frequency (hiss); pink has equal energy per octave (rain, surf); brown is darker still (rumble, distant wind). Through a filter and an envelope it makes hi-hats, snares, wind and waves.

Colour	white · pink · brown
Level	0.00 – 1.00 · default 0.40

SamplerSources

Plays a recording at the pitch of each note: record with the microphone, load a file or use a sound from MathLab.

Press Record on the module to record from your microphone (the browser asks for permission then), Load to open an audio file, or pick one of the built-in synthesised sounds or a sound sent from MathLab. Notes play the sample faster or slower around the Root note; switch off Follow keys to play it unchanged on every note. Start and End trim the sample; Loop repeats that part while the note is held.

KickSources

A synthesised bass drum: a falling sine with a click.

Plays on every trigger, or only on the note set by Plays on (C2, MIDI note 36, by default: the General MIDI kick), so one Keyboard or drum region can play a whole kit. The note shows in the module’s title; turn the knob fully left to play on every note. Sweep sets how far the pitch falls (punch), Drive adds weight.

SnareSources

A synthesised snare: two tuned bodies and a burst of filtered noise.

Tone tunes the drum body, Snappy sets the level of the snare wires (noise), Colour their brightness. Plays on D2 (MIDI 38) by default.

Level	0.00 – 1.50 · default 0.75

Hi-hatSources

A synthesised hi-hat from six detuned square waves and noise.

A short Decay gives a closed hat, a long one an open hat (use two modules, on F♯2 = 42 and A♯2 = 46). A new hit cuts off the previous one, as on a real hi-hat. Metal blends the ringing square-wave cluster against plain noise.

Shaping 9 modules

Filter, amplify, envelope and modulate signals.

FilterShaping · one per voice

Removes highs (low-pass), lows (high-pass), all but a band (band-pass) or a narrow band (notch).

Reso (resonance) boosts the frequencies right at the cutoff; turn it up for the classic squelch. A signal at Cutoff moves the cutoff by up to Mod amt octaves: patch an envelope there for plucks, or an LFO for a wah.

in · Inin · Cutoffout · Out

Type	lowpass · highpass · bandpass · notch
Cutoff	20.0 Hz – 18.0 kHz · default 1.20 kHz
Reso	0.50 – 25.0 · default 1.00
Slope	12 dB · 24 dB
Mod amt	-6.00 oct – 6.00 oct · default 3.00 oct

VCAShaping · one per voice

An amplifier controlled by a signal: patch an envelope into CV to shape each note.

The output is the input × (Open + CV × CV amt) × Level. With nothing in CV and Open at 0 it is silent, as on a real modular: patch an envelope (for notes) or an LFO (for tremolo) into CV, or turn up Open.

in · Inin · CVout · Out

Open	0.00 – 1.00 · default 0.00
CV amt	0.00 – 1.00 · default 1.00
Level	0.00 – 2.00 · default 1.00

EnvelopeShaping · one per voice

Attack, decay, sustain, release: a control signal that rises and falls with each note.

When a note starts it rises to the top in Attack, falls to Sustain in Decay and stays there while the key is held; when the key is released it falls to zero in Release. Velocity sets how much harder key presses make it bigger.

in · Gateout · Out

Attack	1 ms – 10.00 s · default 5 ms
Decay	1 ms – 10.00 s · default 250 ms
Sustain	0.00 – 1.00 · default 0.60
Release	2 ms – 20.00 s · default 350 ms
Amount	0.00 – 1.00 · default 1.00
Velocity	0.00 – 1.00 · default 0.50

LFOShaping

A slow oscillator for movement: vibrato, wah, tremolo, panning.

Swings between −Depth and +Depth (or 0 and Depth when Unipolar). Sync locks the rate to the tempo, for example 1/4 for one cycle per beat. Random jumps to a new value each cycle.

in · Rateout · Out

Wave	sine · triangle · saw · square · random
Rate	0.01 Hz – 40.0 Hz · default 1.00 Hz
Sync	free · 4/1 · 2/1 · 1/1 · 1/2 · 1/4 · 1/8 · 1/16 · 1/32 · 1/4t · 1/8t · 1/16t · 1/8d · 1/16d
Depth	0.00 – 1.00 · default 1.00
Unipolar	on/off, default off
Rate amt	0.10 Hz – 40.0 Hz · default 4.00 Hz

Sample & holdShaping

Takes a sample of a signal and holds it: random steps for bleeps and computer sounds.

Samples its input (or its own noise when nothing is patched in) at Rate, or on each trigger at Trig. Slew glides between the steps.

in · Inin · Trigout · Out

Rate	0.05 Hz – 40.0 Hz · default 4.00 Hz
Slew	0 ms – 2.00 s · default 0 ms

RandomShaping

A random control signal: smooth curves, steps or a slow wandering drift.

Smooth glides to a new random value each cycle, steps jumps, and drift wanders like a leaf on water. At very low rates it gives the slow, never-repeating change soundscapes need.

out · Out

Mode	smooth · steps · drift
Rate	0.01 Hz – 20.0 Hz · default 0.30 Hz
Depth	0.00 – 1.00 · default 1.00
Unipolar	on/off, default off

MixerShaping · one per voice

Mixes up to four signals, each with its own level.

Works for sound and for modulation (for example to add two LFOs).

in · 1in · 2in · 3in · 4out · Out

Level 1	0.00 – 1.00 · default 0.80
Level 2	0.00 – 1.00 · default 0.80
Level 3	0.00 – 1.00 · default 0.80
Level 4	0.00 – 1.00 · default 0.80
Master	0.00 – 2.00 · default 1.00

SplitterShaping · one per voice

Sends one signal to four places, each with its own gain (negative gains invert).

Any output can already feed several inputs; the splitter adds a separate level and polarity for each copy, so one envelope can open the filter a lot and the amplifier a little.

in · Inout · 1out · 2out · 3out · 4

Gain 1	-1.00 – 1.00 · default 1.00
Gain 2	-1.00 – 1.00 · default 1.00
Gain 3	-1.00 – 1.00 · default 1.00
Gain 4	-1.00 – 1.00 · default 1.00

Scale & offsetShaping · one per voice

Multiplies a signal and adds a constant: turn a modulation down, upside down or move its centre.

Output = input × Gain + Offset. Useful to make an LFO only push upwards, or to add a fixed amount to a control.

in · Inout · Out

Gain	-2.00 – 2.00 · default 1.00
Offset	-1.00 – 1.00 · default 0.00

Control 7 modules

Play notes: keyboard, MIDI, sequencers and clocks.

KeyboardControl

Notes from the on-screen keyboard and pads, your computer keyboard, MIDI keyboards and Studio regions.

The note input of an instrument. In Studio mode the notes of the track's regions come out here too, so every instrument starts with a Keyboard module. Switch off MIDI to ignore MIDI keyboards.

out · Notes

Transpose	-24 st – 24 st · default 0 st
MIDI	on/off, default on

MIDI inControl

Notes, a controller knob and pitch bend from a MIDI keyboard or controller.

Channel 0 listens to all channels. CC outputs the chosen controller (1 is the mod wheel) from 0 to 1; Bend outputs the pitch wheel from −1 to 1 (patch it into an oscillator's Pitch with Pitch amt 200 ct for ±2 semitones). Press MIDI under the keyboard to connect. In a patch without a Keyboard module, the computer keys, the on-screen keys and Studio notes play this module too (on its channel), so you can try a MIDI patch without a MIDI device.

out · Notesout · CCout · Bend

Channel	0 ch – 16 ch · default 0 ch
CC no.	0 – 127 · default 1

Step sequencerControl

Plays a loop of up to 16 notes, in time with the tempo or with a clock.

Click a step to switch it on or off and drag it up or down to change its note. It runs on the project tempo at Rate, or one step per trigger when a clock is patched into Clock. Swing delays every second step.

in · Clockin · Resetout · Notes

Steps	1 – 16 · default 8
Rate	4/1 · 2/1 · 1/1 · 1/2 · 1/4 · 1/8 · 1/16 · 1/32 · 1/4t · 1/8t · 1/16t · 1/8d · 1/16d

ArpeggiatorControl

Turns held chords into running patterns.

Hold a few keys and it plays them one after the other at Rate, over one or more Octaves. With Latch on the pattern keeps going after you let go, until you play a new chord.

in · Notesout · Notes

Mode	up · down · up-down · random · as played

Octaves	1 – 4 · default 1
Gate	5% – 100% · default 60%
Latch	on/off, default off

ClockControl

Steady triggers in time with the tempo.

Fires at Rate. Triggers are notes too (on Note), so a clock can play a drum or open an envelope directly.

Clock dividerControl

Passes on every 2nd, 3rd, 4th and 8th trigger.

One clock in, four slower clocks out: hi-hats on ÷2, kicks on ÷4, a change every ÷8. ÷3 against ÷4 gives cross-rhythms.

in · Inin · Resetout · ÷2out · ÷3out · ÷4out · ÷8

EuclideanControl

Spreads a number of hits as evenly as possible over a number of steps: rhythms found all over the world.

3 pulses in 8 steps is the tresillo, 5 in 8 the cinquillo, 5 in 16 a bossa nova pattern. Rotate shifts where the pattern starts. Use it with a clock or on its own Rate.

Effects 17 modules

Reverb, delay, modulation, distortion and dynamics. Also used as mixer inserts.

ReverbEffects

A room, hall or endless space, from impulse responses made on the fly.

The reverb is a convolution with a decaying burst of noise generated in your browser (no recordings of real rooms). Size is the decay time, up to 30 seconds for soundscapes; Damping darkens the tail; Pre-delay separates it from the dry sound.

in · Inout · Out

Width	0.00 – 1.00 · default 1.00
Mix	0% – 100% · default 35%

ShimmerEffects

A huge reverb whose tail keeps rising an octave: for space pads and cosmic swells.

A long algorithmic reverb whose output is pitched up (by the grain engine) and fed back in, so each pass of the tail sounds an interval higher, like a choir of harmonics building above the sound. Shimmer sets how much is fed back; keep it below 0.7 for a tail that fades.

in · Inout · Out

Size	1.00 s – 30.00 s · default 8.00 s
Damping	800 Hz – 18.0 kHz · default 7.00 kHz
Shimmer	0.00 – 0.90 · default 0.45

Width	0.00 – 1.00 · default 1.00
Mix	0% – 100% · default 50%

Ping-pong delayEffects

Echoes that bounce between left and right.

Sync sets the delay in note values at the project tempo (dotted eighths are a favourite); choose free to use Time. Feedback sets how many echoes, Tone darkens each repeat.

Mix	0% – 100% · default 35%

Tape delayEffects

A warm, wobbly echo, darker and dirtier with every repeat.

Models a tape echo: each repeat passes through a gentle saturation and a low-pass filter, and Wow lets the speed drift. Feedback above 1 runs away (carefully).

in · Inout · Out

Time	30 ms – 2.00 s · default 320 ms
Sync	free · 4/1 · 2/1 · 1/1 · 1/2 · 1/4 · 1/8 · 1/16 · 1/32 · 1/4t · 1/8t · 1/16t · 1/8d · 1/16d

Depth	0.00 – 1.00 · default 0.50
Delay	5 ms – 40 ms · default 18 ms
Mix	0% – 100% · default 50%

FlangerEffects

A sweeping jet-plane whoosh.

A very short delay that sweeps up and down, mixed with the original. Feedback makes it ring; negative feedback sounds hollower.

Downsample	1 – 40 · default 4
Mix	0% – 100% · default 100%

TremoloEffects

Pulses the volume up and down.

A sine wave gives a soft throb, a square wave a choppy gate (try 1/16 sync).

PumpEffects

Ducks the sound on every beat and lets it swell back: the breathing, pumping sound of house music.

Works like a compressor triggered by the kick drum (sidechain compression), but locked to the beat, so no kick is needed. Depth sets how far the sound drops, Release how quickly it swells back, Beat how often (quarter notes for four-on-the-floor). Put it on basses, chords and pads, not on the drums themselves.

RainSoundscape

Synthesised rain: drops, an optional tin roof and a soft hiss.

Each drop is a tiny rising tone (as an air bubble forms) at a random place in the stereo field; Tin roof lets drops ring a set of metal resonances. Turn Density down for a drizzle, up for a downpour.

WindSoundscape

Wind from filtered noise, with gusts and whistling.

Pink noise through two moving band-pass filters. Gusts and Speed set how much and how fast it changes; Whistle narrows the filters until the wind sings.

Grain cloudSoundscape

A texture made of thousands of tiny pieces of a sample.

Pick a sample (record one, load one, use a built-in sound or one from MathLab). Grains are taken around Position, scattered by Spray. When notes are patched in, the cloud plays only while a note is held, transposed by the note (C4 is unchanged).

DriftSoundscape

Four slow, independent random wanderings: modulation that never repeats.

Patch them into filter cutoffs, panning, levels and pitch for sounds that keep changing very slowly. At 0.01 Hz a full swing takes minutes.

GenerativeSoundscape

A melody that slowly changes: a loop that rewrites itself.

Keeps a loop of Length notes from a Scale. Each time a step comes round, it is rewritten with probability Change, and plays with probability Density. At 0 it repeats exactly; at 1 it is all new; in between it never quite repeats.

Long reverbSoundscape

A reverb that hangs for up to half a minute.

An algorithmic reverb (eight delay lines feeding each other, darkened and gently moving), set up for spaces: long, dark and wide. Unlike the convolution Reverb it costs the same at any length, so it is the one to use for very long tails. Put it after a drone or a sparse melody.

Output & scopes 2 modules

Send the patch to the speakers and look at signals.

OutputOutput & scopes

Where the patch leaves for the mixer and your speakers.

Everything patched in is heard. In Studio mode the output goes to the track's channel in the mixer. The meter shows the level.

ScopeOutput & scopes

Shows signals as a waveform or a spectrum.

Patch any output into A (and B, in a second colour). The waveform view is triggered so repeating sounds stand still; the spectrum shows which frequencies are in the sound.
