DUO ORG5.10Two notes struck as one, moving in parallel thirds

Every patch on the Moog Subsequent 37

The technique

Two notes, a third apart, struck as one. The name says duo, and the figure is what the second note is for: it moves with the first, by the same amount, every time, so the pair is one hand and not two lines.

Three stabs a bar: the one, the "and" of two, the "and" of three. The one is three sixteenths long, the second is two, the third is four and holds into beat four. Then silence to the bar line.

The pair is the third and fifth of the chord, never the root, over each of the four chords. Somebody else plays the root, or nobody does.

Move both notes together on the bar head and change nothing until the next one. Down a third, down a third, up a step, and back up to the top on the next pass. The interval never changes; only where it sits.

Strike both notes at the same instant. A pair with one note a hair early is two notes, and the whole figure rests on their being one.

The one is the loud stab and the "and" of three the next. The "and" of two is the light one, played under, so the bar has a shape and not three equal hits.

GLIDE

  • 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 MODEON

    On: the two oscillators take independent pitches, so this patch plays two notes

  • OSC · KB CTRLLO

    HI puts OSC 2 on the top note and OSC 1 on the bottom; LO swaps them

  • OSC 2 · FREQUENCY-0.5st(-7…7 st)

    Leave near centre: this is a detune on top of a note OSC 2 is already playing

MIXER

    With nothing in EXT IN this feeds the mixer output back into itself

FILTER

    Fully down closes the filter completely

  • RESONANCE3(0…10)

    Above 7 the filter sings by itself

  • MULTIDRIVE2(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 TRACK0.5(0…2)

    1.0 is 1:1 tracking centred on C3; 2.0 is 2:1
