Wavetable synth

The Wavetable synth is the synth designed for movement: a timbre that travels while the note
plays. Pads that breathe, basses that growl open, leads that talk, glassy keys. It is a notes instrument: it plays whatever notes reach it, from the keys, MIDI, the piano roll or a
sequencer.

It loads as the plainest sound there is, a pure sine at the key: Osc 2 and the sub are off, the
filter is open and nothing in the matrix moves anything. Everything else is yours to bring in.

The Wavetable synth set as a vowel pad: Rings on the screen, Osc 1 on Vowels and Osc 2 on Choir with their rows of numbers, the low-pass filter at 6 kHz, the Amp envelope, and the folded Matrix and Voice columns.

How it makes a sound​

Each oscillator reads a wavetable: a row of eight single-cycle waves, from the table's tamest
(always first) to its wildest. Position says where in the row it reads; between two waves it
morphs smoothly from one to the next. Moving Position while a note plays is the whole idea: it is the
first knob to put on an axisOne of an Orbiter's three performance controls: X, Y and Z..

Two oscillators, each with its own table, Position and effect, and a sine sub under them, go
through one filter and the amp. Two envelopes, two LFOs, the key, velocity, the mod wheel and a
random value per note can move almost anything through the matrix.

Oscillators​

  • 1Tables. The two menus in the title are Osc 1's and Osc 2's tables, sixteen in four kinds:
KindTables
BasicSine → Saw, Saw → Square, Pulse (a square narrowing to a needle), Triangle → Saw
SpectralResonant (the classic formant sweep), Comb, Metal (glassy, bell-like), Phase (one spectrum, a shape that moves)
VocalVowels (ah → oo), Choir, Throat, Whistle
KeysDrawbars (organ registrations), E-piano, Clav, Glass
  • 2Effects. The line under the title holds each oscillator's effect. Its amount is the knob
    captioned with the effect's name (FM 1, Warp 2 …); at 0 it does nothing.

    • FM: the other oscillator modulates this one. Osc 2's Semi is the FM ratio.
    • Sync: the wave is read faster and restarted every cycle: the tearing sync sweep.
    • Warp: the first part of the cycle is squeezed and the rest stretched, a pulse width for any
      wave.
    • Fold: the wave is folded back on itself, brighter and buzzier as the amount rises.

    A new table lands on the next note, so a held note never jumps. Only the chosen effect is built
    into the instrument, so changing it rebuilds the instrument, as Voices does: held keys strike again. Osc 2 keeps
    feeding Osc 1's FM even while it is switched off, so it can be a pure modulator.

  • 3The table of numbers. One row each for 1, 2 and Sub: the hexagon switches it on
    and off (its settings are kept), then Detune (cents), Semi (semitones against the key) and
    Gain. The sub's Octave (one or two under the key) sits in the Semi column. Switching Osc 2
    or the sub on is heard at once: their gains start at 100 % and 60 %.

  • 4The knobs on the bottom line: Position 1, Osc 1's effect, Position 2, Osc 2's effect.

Filter​

5One filter with four types, the glyphs in its title: low-pass, band-pass, high-pass and
notch, 12 dB an octave. Changing the type glides, without a click. Cutoff is over
Resonance; resonance rings at the cutoff but never whistles on its own.

Mod sources​

6Five tabs, one graph size on every tab, so nothing jumps when you switch:

  • Amp: the envelope every note goes through, with Velocity (how much a note's velocity moves
    its level; at 0 every note is full) and Level.
  • Filter: the filter's own envelope, with Envelope (how far it moves the cutoff, in octaves,
    up or down).
  • Mod: a third envelope with nothing of its own: it moves things through the matrix (its Env
    column).
  • LFO 1 and LFO 2: each reads one of the Orbiter's LFOs (the dimension's X and Y as it loads): its
    menu, its hexagon (on/off), the LFO's Rate in, Rate, Shape and Depth, shared with
    whatever else reads it, then Amount (how much of the LFO gets through). What it moves is the
    matrix's.

Drag an envelope's points, or type a value under it. Attack, Decay and Release can be bent: see Envelopes.

Matrix​

The 7Matrix starts folded; open it from its column. It is the Matrix every notes instrument shares:
what can move down the side, what moves it across the top, an amount in each cell, in two tabs.

TabSources (columns)Targets (rows)
ModulationEnv (the Mod envelope), LFO 1, LFO 2Pitch (both oscillators and the sub, up to ±12 semitones), Pos 1, Cutoff (up to ±5 octaves), Pos 2, Pitch 2 (Osc 2 only), Fx 1, Fx 2 (the effects' amounts), Gain 2, Res, Unison (its Amount)
MIDIVel (velocity), Key (around C3), PB (pitch bend), Press (pressure), Mod (the mod wheel), Rand (a value drawn for each note)the same rows, then LFO 1 and LFO 2 (each LFO's Amount)

Hover a cell to read its route ("LFO 1 · 1cX › Cutoff": the slot, then the LFO plugged into it).

Key › Cutoff at 100 % is the cutoff following the keyboard exactly, and PB › Pitch is the
pitch bend, two semitones until you change it. The Wavetable has no Vibrato or Level row: its two
LFOs and its Gain rows do that work.

Voice​

8Folded at first. Mono and Legato (with Mono, a note played over a held one slides there
without a new strike, over Glide), Voices (how many notes sound at once), and Unison:
copies of each oscillator per note, 1 (off) to 4, spread by Amount. Classic detunes
the copies (up to ±50 cents); Position spreads them across the table instead.

At Unison 4 you get four notes at once; the Voice group says so.

The screen​

9The screen is a square at the left of the panel, the drawer's full height. The glyphs in its top-right
corner pick one of two pictures:

  • Rings (the first): each table as growth rings, its first wave innermost. Osc 1 is the left
    half, drawn in the accent, Osc 2 the right half. The ring being played grows outward with Position
    and breathes with the note; the sub is the heartwood in the middle.
  • Terrain: each table as a receding stack of its eight waves, Osc 1 above, Osc 2 below, the wave
    being played riding through it. The rail on each stack's left shows its Position: tap a step of the
    rail to jump to that wave.

A faint bar beside a Position shows how far the matrix can move it.

Playing the waves​

The waves are the controls. Drag up or down for the first value, sideways for the second, or
both at once on a diagonal; hold Shift to move them finer. While you hold one, its name and values show above it.

WhereUp or downSidewaysDouble-click
Osc 1: the left half (Rings), the upper stack (Terrain)Position 1Effect 1's Amount (FM, Sync, Warp or Fold)Osc 1 on or off
Osc 2: the right half (Rings), the lower stack (Terrain)Position 2Effect 2's AmountOsc 2 on or off
Sub: the heartwood (Rings), the dot at the head of its line along the foot (Terrain)Sub GainSub on or off

A Sub switched off is a faint dashed ring, so there is always something to double-click.

The corners​

  • Resonance is the number at the top left, in %.
  • Cutoff is the meter at the bottom left.
  • Level is the ladder at the bottom right, under the view glyphs.

Drag a corner up or down; double-click it to put it back to its default.

Try it​

  • A pad that speaks. Set the Vowel pad row above and hold a chord: LFO 1 moves Position 1 through the vowels.
  • The classic sweep. Set the Classic sweep row and play single notes: every note runs through the table as its envelope falls.
  • Position under your hand. From the defaults, map Position 1 to an axis and hold a note: the wave morphs as the axis moves. It is the first thing to map on this instrument.

Mapping​

In the Studio's Map mode, every number can be driven by an axisOne of an Orbiter's three performance controls: X, Y and Z.. Two to try first:

  • Position 1 and 2: the signature move, one up and the other down on one axis
  • Cutoff, or an effect's amount for a growl

Toggles can switch 1, 2 and the Sub on and off, and flip the sub's Octave, Unison's mode,
the LFOs' on/off, Mono and Legato. The tables, effects, filter type and LFO inputs are never on
an axis: a preset carries them.

In a room​

Everyone in a roomA session that several people join to play the same Orbiters together, each on their own device. hears the same notes and the same sound, LFOs included (they are the
Orbiter's, on the same phase for everyone, someone who joins late too); only the mod wheel is your own.
