IA Circus

A barrel organ / calliope synthesizer with pipe harmonics and mechanical wobble.

0. Overview

IA Circus is a local generative calliope and barrel-organ instrument. Additive synthesis generates organ pipe tones with configurable harmonic content. Tremolo and wobble add the characteristic mechanical instability. No external AI backend is required.

Example uses:

Fairground / circus atmospheres
Mechanical organ melodies
Vintage carousel music
Theatrical clown performance

1. Controls

1.1 Volume

Output level in dB.

1.2 Register

Pipe register selection:

Flute 8' — soft, few harmonics
Flute 4' — one octave higher, brighter
Principal — full, rich harmonics
Mixture — all harmonics, brilliant and complex

1.3 Harmonics

Intensity of upper harmonics (0-100%).

1.4 Tremolo Rate / Depth

Speed and depth of amplitude tremolo.

1.5 Wobble

Mechanical pitch instability — simulates an imperfect hand-cranked mechanism.

1.6 Attack / Release

Pipe opening and closing time.

1.7 Air

Amount of breath/air noise mixed into the signal.

1.8 Detune

Slight detuning between pipes in cents.

2. MIDI

Fully chromatic — play chords and melodies. Each note triggers an independent pipe voice.
