CHAPTER 54 OF 54 · REFERENCE

Quick reference

A lookup for the whole instrument. Each row names a control or gesture and links the chapter that explains it. Ranges, Init values, Matrix rows and CCs are in Parameter reference.

#Signal order

Engine signal flow, from The three engines.
Engine signal flow, from The three engines.

Each voice: generator and Sub → Distort → Noise joins → low-pass gate → Filter. The amp envelope, driven by pressure, modulates the low-pass gate, which sets level and brightness together. The SEM-style Filter follows the gate, so it receives the enveloped signal; INK reverses the usual oscillator → filter → amplifier order.

Each engine: sum of 8 voices → saturation → High Pass → CHORUS / PHASER → Synth Lvl into the peak compressor, with Stereo Width → Level, Mute, Solo → DELAY and REVERB sends → Main Wet/Dry → MULTIBAND → AUDIO OUT (Main or own bus) → OUTPUT → limiter.

#Gestures

#Knobs and pads

GestureResult
Drag a knob up or downTurns it. A slow drag makes fine changes; a fast sweep covers the range quickly.
Rest the finger on a knob for a moment, then dragFine adjust: the whole drag turns at the slow rate. On a Mac: Shift-drag.
Double-tap a knobReturns it to its reference value, the value saved in the sound.
Quick vertical swipe that starts on a knobScrolls the page.
Drag a Matrix cell up or downSets its amount, −100 to +100; up is more. A faster drag covers more range; rest the finger first for fine changes. On a Mac the scroll wheel moves the list (Modulation matrix).
Double-tap a Matrix cellClears it to 0.
Double-tap a level fader (mixer or engine strip)Returns it to 0.0 dB.
Double-tap the XY padThe dot glides back to the centre.

#Notes and chords

GestureResult
Tap Hold, play, liftThe notes latch.
Quick tap on a latched pad, key or chord tileThat note or chord is released.
Long press a latched pad, key or chord tileThe finger plays its pressure live. On lift it stays latched at the lifting pressure (Play the Grid).
Double-tap HoldHold turns off and every latched note of the engine is released.
Drag along the Voicing or Spread railSets its value, 0 at the left to full at the right. It acts on the next chord and stays after the lift (Chord colour).
Quick tap at the end of a rail's fillReturns the rail to 0 (Chord colour).
Double-tap Hold on a Chords engineAlso returns both rails to 0 and turns off Spice latched under Hold (Chord colour).
Quick tap on Spice, Lean or FillLatches it on or off.
Long press Spice, Lean or FillOn while the finger stays, off when it lifts.
Long press Spice with Hold onSpice stays on after the finger lifts. Lean and Fill stay momentary.

SectionWhat it does, and its controlsHome
Engine stripThe engine's level fader with its dB value, Mute (speaker icon) to silence the engine, S to solo itMixer and All page
SAMPLERWhich sample plays and how the grains read it. Tape or Pitched sets how a note picks its slice and pitch; the play style, whether the playhead plays once or loops, in the slice or the whole sample. Kit opens the kit view, Sample picks the slot, Scrub offsets each grain's start, Grain size sets the time between grain starts, Rate the speed of grains and playhead, Timestretch the playhead's speed alone.Granular sampler
SAMPLER JITTERRandom variation per grain: Scrub jit. of its start, Grain jit. of its interval, Rate jit. of its read speedGranular sampler
OSCThe generator and the voice before the gate. The generator box chooses the generator (with the bank box under it on Wavetable); A and B are the macros. Detune, Width, Position or Wave is the generator's main tone control. Distort drives the gate and the engine's saturation, Octave and Pitch transpose and tune the sound, Glide sets portamento, Interval transposes one stereo channel, Noise adds white noise, LPG Filter sets the gate's resonance. Degree, Microtone and Stride set the Grid layout. On the Granular sampler, the tone control and LPG Filter are not shown.Oscillators
PHASEThe Phase generator's two phase-distortion oscillators, A and B. DCW bends both from a sine to the full wave, Detune detunes B against A, Osc B sets B's level and the ring's depth, B Pitch B's interval, Ring crossfades from the mix to the ring product, Drift adds slow random pitch wander.Phase
SUBOne sub oscillator under the lowest held note: Level (0.0 is off), Shape from sine to near square, Octave against the noteSub oscillator
FILTERThe SEM-style multimode filter after the gate: Cutoff, Resonance, Mode from low-pass through notch to high-pass, the Band-pass box for the band-pass output, Filter Spread to widen the sound by detuning the left and right filtersFilter
ENVELOPEThe amp envelope, which drives the low-pass gate: Sensitivity scales how much pressure reaches it, then Attack, Decay, Sustain, ReleaseAmp envelope
ENVELOPE 2The modulation envelope, Matrix source Env: Env Level scales every Env cell, then Attack, Decay, Sustain, ReleaseEnvelope 2 and Random
MOD A, MOD BThe LFO added to each macro: Depth, Rate, Shape, and Warp, which moves the turning point inside each cycleLFOs and Freeze, Macros and dice
LFO X, LFO YThe two free LFOs, Matrix sources X and Y: the same controls, plus Offset, a constant added to the output, and the Freeze box, which keeps one value until every note is silentLFOs and Freeze
CHORUS / PHASERAn insert on the whole engine. The type menu chooses Chorus or Phaser. Mix sets the effect level (0% bypasses it), Center the chorus delay time, Sweep in its place the phaser's centre frequency. Depth and Rate set the width and speed of the movement, Feedback raises resonant peaks, Tone sets the colour of the effect signal, Stereo sets the left-right difference.Chorus and phaser
DELAYA send delay. The type menu chooses Classic, Reverse, Octave or Ping-Pong. Send sets the level in, Time the delay time, synced or free, 2nd Tap the right side's time as a share of Time, Wobble a tape-like drift of the time (Classic only), Feedback how long the repeats last.Delay
REVERBA send reverb: Send sets the level in, Time the decay, Shimmer an octave-up shifter in the loop, Wobble slow modulation that detunes the tailReverb and mix
MULTIBANDCompression and level for three bands of the engine's output, Low, Mid and High: positive values compress and raise the band, negative values cut itMultiband
MIXLevels, width and low cut inside the engine's chain: Synth Lvl sets the level into the engine's peak compressor and the sends, Main Wet/Dry the dry signal against the delay and reverb returns, High Pass a low cut before CHORUS / PHASER, Stereo Width the dry signal's widthReverb and mix
OUTPUTGain of INK's whole output, saved with the projectMixer and All page

#Matrix, Arp and Seq

Matrix sourceSignal
EnvEnvelope 2, scaled by Env Level. Unipolar.
PrsPressure: touch, MIDI velocity, aftertouch or MPE Slide. Unipolar.
A, BMacro A and Macro B, each with its MOD LFO. Bipolar.
X, YLFO X and LFO Y, with their Offset. Bipolar.
RndA random value drawn at each new note.

The destination groups follow the sections of the Sound and Arp tabs. In the Matrix's order: OSC, PHASE, SUB, FILTER, PITCH, AMP ENV, ENV 2, SAMPLER, SAMPLER JITTER, MOD A, MOD B, LFO X, LFO Y, ARP, CHORUS / PHASER, DELAY, REVERB, MULTIBAND, MIX. PITCH gathers the tuning and Grid-layout controls with the key's Root and Scale. PHASE rows act only on a Phase sound, SAMPLER and SAMPLER JITTER only on a Granular sampler sound.

Some rows are named differently from their knobs, such as Synth level for Synth Lvl and LFO rate for an LFO's Rate; Parameter reference gives each row's name. On a Chords engine the Stride and Degree rows read Voicing and Spread (Modulation matrix).

The Arp and Seq parameters, in the order of the Arp tab, then the Seq tab:

ParameterWhat it doesTab
Tempo, SyncThe current pattern's tempo, and whether the engine follows the master clockArp, Seq
ModeThe order the held notes play inArp
DirectionThe order the playhead takes through the pattern's loopSeq
DivisionThe length of one stepArp, Seq
Probability, EuclidWhich steps play: by chance, or as a Euclidean rhythm with Probability as its densityArp, Seq
GateHow much of each step a note soundsArp, Seq
TransposeThe order of the arp's passesArp
ShiftThe interval between passesArp
RangeThe number of passes before the figure starts againArp
Step offsetMoves the loop along the pattern, in stepsSeq
QuantizeMoves live takes toward the step grid; saved with the projectSeq

Tempo, Sync and Gate are the same controls on both tabs and belong to the engine's current pattern. Division, Probability and Euclid are separate controls on each tab (Arp rhythm and tempo, Pattern playback). On Strum, Transpose, Shift and Range are greyed.

  2. Amp envelope: level and brightness over time (Amp envelope).
  3. Filter: Cutoff, Resonance, Mode (Filter).
  4. Expression: a Prs or Env cell, such as Prs → Cutoff, +30 (Modulation matrix, Envelope 2 and Random).

  6. Effects and output: the CHORUS / PHASER insert, the DELAY and REVERB sends, MIX and MULTIBAND (Chorus and phaser, Delay, Reverb and mix, Multiband).

#Build a performance

  1. Roles: one per engine, for example bass, chords, lead (The three engines).
  2. Levels: the mixer on the All page (Mixer and All page).
  3. Timing: Tempo and Sync per pattern, Engine 1 or the host as master clock (Clock and sync).
  4. Harmony: FOLLOW for engines that move with another engine's chords; Key Lock for an engine that keeps its key when another engine or a pattern changes key (Key lock and Follow).
  5. Save the project (Projects).

#Commonly confused controls

ControlNot to be confused with
Hold (CC 69) latches notes after you lift; a tap on a latched pad releases one.The sustain pedal (CC 64) holds MIDI notes until the pedal comes up, then releases them all.
Arp plays the held notes one per step, repeating.Strum plays notes struck together once, one after another, and lets them ring.
Strum is a PLAY mode, on the Arp tab and the engine sheet.Strings is a keyboard. PLAY is greyed on it: neither the arp nor Strum plays.
Range on the Arp tab is the number of passes of the arp figure, each moved by Shift.Octave in OSC transposes the sound.
The Octave arrows move the keyboard's octave; the sound, MIDI and patterns stay.Octave in OSC transposes the sound and is saved with it.
Root (engine sheet › KEY) is the key's tonic, saved with the project. MIDI notes play without it.Pitch in OSC is the sound's tuning, saved with the sound, applied to every note.
The XY pad on the All page moves Macro A and Macro B.X and Y in the Matrix are LFO X and LFO Y.
Tempo, Sync and Gate belong to the engine's current pattern; loading a sound keeps them.Mode, Division, Probability, Euclid, Range, Transpose and Shift are your arp settings, or the sound's when it was saved on Arp or Strum.
Level (engine strip, mixer) is the engine's level, saved with the project.Synth Lvl in MIX sets the level into the engine's peak compressor and the sends, saved with the sound. OUTPUT sets INK's whole output.
Mute silences the engine's audio. Its arp, pattern and MIDI out keep running.MIDI Out Off stops the engine's MIDI; its sound plays on.
Slide control sets how pitch follows a slide on Keys and where it lands.Glide in OSC is the time a voice takes to reach a new pitch.
Sensitivity in ENVELOPE scales pressure for this sound.Sensitivity on the Touch page sets how hard a touch must be, for every sound.
Undo (curved arrow) in the Seq transport steps back through the pattern's note edits and takes, up to 40, with no redo.The edge swipe and three-finger swipe undo and redo the last 20 changes to the sounds, keys, mixer settings and patterns.
Save replaces the saved version of the sound.Save as new... keeps the original and stores a new sound.
