Oscillator 3 is a Triangle wave synthesizer, playable via MIDI or as an AUv3.
Useful as an educational tool to learn about synthesis parameters such as envelopes and modulation, or as a creative tool when you need a pure triangle wave.
Drone mode plays any notes back continuously at the level set by the 'Sustain' knob.
Layer with other apps in the Oscillator series to create rich evolving textures.
