TRIPLET 5THS9.11Fifths stacked three at a time, accented in threes across the beat
The technique
The name says fifths, so every note in a group is a fifth from the one before it, three at a time. Up from the root: root, fifth, second. Then up from the fifth: fifth, second, sixth. Then up from the second: second, sixth, third. That is the ladder, and every rung is a fifth.
The name says triplet, so the notes come in threes: three sixteenths, the first of each three the loud one. Four groups in a row is an accent every three sixteenths against a beat every four, and that cross-rhythm is the figure. Do not straighten it out.
The fourth group comes down the same rungs: the third, the sixth, the second, a fifth below each time, landing on the second. Then a beat of nothing. Twelve sixteenths climbing and turning, four of silence, and the next bar starts the ladder again from its own root.
Bar two is the same ladder from the IV’s root, over the IV: the same twelve notes and the silence, every one a fifth lower. Same shape, same accents.
One note at a time, every note the same length. Let each sixteenth go before the next is struck. Held, three fifths are a chord, and this is not a chord; it is a ladder.
The bar head is the loudest note and the start of each group the next loudest. The third note of every group is the quiet one, so the ear counts in threes and not in fours.
Never raise the key’s fourth. It is the next fifth up from the seventh, one rung past the key, and one of them turns the ladder into a modulation. The ladder stops at the third and turns.
The chords
2 chords over 2 bars, in G major.
| Degree | Chord | Notes | Bars | Under the figure |
|---|---|---|---|---|
| I | G | G · B · D | 1–1 | ● |
| IV | C | C · E · G | 2–2 | ● |
The figure is played over these chords; supply them separately if your rig allows.
The rules
- Never the raised 4th, on any chord — over I, the seventh fifth up from G is one rung past the key, and one of them is a modulation.
The notes
2 bars in G major. Each note is in force across the steps shown.

Settings
- SWING50%(0…100 %)
50 is straight; it swings the onboard arpeggiator and sequencer, nothing played from elsewhere
PRESET EDIT, ARPEGGIATOR, SWING
ARPEGGIATOR
- ONON
Lit, or nothing below does anything
- SYNCON
On, RATE picks a division; without MIDI clock or tap tempo the arp will not play
- RATE (division)1/16
At SEQ this is the step length
RATE picks divisions while SYNC is lit
- RANGE0
The notes held, and no octave above or below; past either end lights two LEDs and spans three
- BACK / FORTHOFF
Off, or the pattern turns round at each end
- INVERTOFF
- PATTERNUP
ORDR sounds held notes in the order pressed; SEQ plays back a recorded step sequence
- LATCHOFF
Off, so releasing the keys stops it
GLIDE
- ONOFF
Must be lit for any glide at all
OSCILLATORS
- OSC 1 · OCTAVE8'
- OSC 1 · WAVETRIANGLE
The knob is continuous; these are its four named points
- OSC 2 · OCTAVE8'
- OSC 2 · WAVETRIANGLE
The knob is continuous; these are its four named points
- OSC · HARD SYNCOFF
Keep OSC 2 at or above OSC 1 or it barely sounds
- OSC · KB RESETON
A defined leading edge, at the cost of a click on hard attacks
- OSC · DUO MODEOFF
Off: one note at a time, both oscillators on the same key
- OSC · KB CTRLHI
Inert while DUO MODE is off; set so FREQUENCY keeps its semitone scale
- OSC 2 · FREQUENCY0st(-7…7 st)
Centre is unison with OSC 1; fully clockwise is a fifth
- OSC 2 · BEAT FREQ0Hz(-3.5…3.5 Hz)
A constant beat rate at every pitch, unlike FREQUENCY
MIXER
- OSC 15(0…10)
- SUB 12.5(0…10)
Always a square, always an octave below OSC 1
- OSC 22(0…10)
- NOISE0(0…10)
Pink, not white
- FDBK / EXT IN0(0…10)
With nothing in EXT IN this feeds the mixer output back into itself
FILTER
- CUTOFF1800Hz(20…20000 Hz)
Fully down closes the filter completely
- RESONANCE1.5(0…10)
Above 7 the filter sings by itself
- MULTIDRIVE0(0…10)
Tube-like warmth at the bottom, hard clipping at the top
- SLOPE24
dB per octave: one, two, three or four poles
- EG AMT2.5(-5…5)
Bipolar: below centre the envelope pulls the cutoff down
- KB TRACK1(0…2)
1.0 is 1:1 tracking centred on C3; 2.0 is 2:1
ENVELOPE GENERATORS

- AMP EG · MULTI TRIGOFF
On, every note re-attacks even when you play legato
- AMP EG · LOOPOFF
Off on everything but a bed: looping the amplitude re-articulates a held note
MOD 1
- SOURCETriangle
- HI RANGEOFF
On, the LFO runs ten times faster
- SYNCOFF
Off, so RATE is in hertz rather than clock divisions
- LFO RATE5Hz(0.1…100 Hz)
