Synth9 Synth Machine

Electro-Harmonix built the Synth9 to recreate classic synthesizer sounds from a guitar signal. Moog, Sequential Prophet, Oberheim, and more.

Nine synth voices cover lead, bass, pad, and sequence sounds from iconic synthesizers. The algorithm transforms your guitar signal through filtering, oscillator modeling, and envelope shaping.

Mix blends synth with dry guitar. Ctrl adjusts filter and modulation parameters. Polyphonic processing handles chords where appropriate.

Classic synth sounds without the vintage keyboard prices.
