Oscillators

OscillatorsSINE · SAW · SQUARE · PWM · SUPER SAW

The oscillators make their own wave at the note's pitch: a SINE (one partial), a SAW (all of them), a SQUARE (the odd ones), a PWM whose width moves the partials, a SHAPED SAW that turns from saw to sine, a SUPER SAW of two detuned saws, NOISE, and the FM operators that bend a sine with what comes in.

WHAT TO KNOW

THE SPECTRA

SINE: the fundamental alone. SAW: every harmonic, each 6 dB down an octave. SQUARE: the odd ones. TRI: the odd ones, falling faster.

SHAPE AND WIDTH

PWM's width (in %, 50 a square) and SHAPED SAW's shape (0 a saw, 127 a sine) change the spectrum with one row, so a control can sweep them.

FM

An FM OPERATOR is a sine whose phase the input pushes: FM OP Inp sets how far, from a hint of brightness to a metallic clang.

WATCH OUT

Some Pads lower an oscillator's output by default (PWM's width page, LPNOIZ): compare levels with the Pads where the factory leaves them.

IN THE FACTORY PROGRAMS

HOW TO ON YOUR K2700 · 1037 '80s Movie Music

'80s Movie Music is a SUPER SAW: two detuned saws in one function.

  1. In Program mode choose 1037 '80s Movie Music (KEYPAD, 1037, ENTER).

    Program mode with 1037 '80s Movie Music
  2. Press EDIT, then MORE and ALG: Algorithm 5, one place of four blocks holding the SUPER SAW.

    The ALG page of 1037 '80s Movie Music, layer 1, the cursor on Algorithm (5)
  3. MORE, then DSP CTL. The Detune row is 5 ct: how far the two saws sit above and below the key.

  4. Turn the Alpha Wheel up, here to 15 ct: the beating quickens, a wider, more chorused sound.
