SYNTH

An instrument that makes its sound from electricity, not from a string or a column of air, and lets you shape that sound with knobs.

How it makes a sound

  1. 01 Oscillator

    Makes the raw tone. Its speed sets the pitch; its wave shape sets how bright it starts.

  2. 02 Filter

    Takes some of it away, shaping the colour. Turn the cutoff down and the sound gets darker.

  3. 03 Amplifier

    Sets how loud it is. An envelope opens it when you press a key and closes it after you let go.

This is subtractive synthesis, the classic analogue layout · others below
