2. Setup and Connections

To begin using your Intelligent Harmony Machine, follow these connection steps:

1. Connect your instrument to the INPUT jack on the right side of the pedal.
2. Connect the OUTPUT jack on the left side to your amplifier or the next pedal in your signal chain.
3. For a stereo setup or to send your dry signal separately, connect the DRY OUT jack to another amplifier or input.
4. Power the pedal using either a 9V battery or an optional 9V DC power adapter connected to the 9V input.

Proper connection of input and output cables for optimal performance.

3. Controls and Features

Familiarize yourself with the pedal's controls:

• MIX Knob: Adjusts the balance between your dry (unaffected) signal and the shifted/harmonized signal.
• VOL Knob: Controls the overall output volume of the pedal.
• KEY Knob: Selects the musical key (C, D, E, F, G, A, B) for the Intelligent Harmony Mode.
• #/MIN/MAJ Switch: This three-position switch allows you to select between sharp (#), minor (MIN), or major (MAJ) intervals, influencing the harmony generated in Intelligent Harmony Mode.
• INTERVAL Selector (1-11): This rotary switch selects the specific harmony or pitch shift interval. Refer to the pedal's graphic for detailed interval descriptions for each setting.
• MOMENT Button: When pressed, this button enables momentary operation of the footswitch, meaning the effect is active only while the footswitch is held down. It also allows for sweep time adjustments in secondary mode.
• POLY OVERRIDE Button: Engages the Polyphonic Override Mode, allowing the pedal to act as a standard polyphonic pitch shifter, applying shifts to chords as well as single notes.
• DRY OUT Jack: Provides an unaffected output of your instrument's signal, useful for parallel processing or stereo setups.

4. Operating Modes

The Intelligent Harmony Machine offers versatile operation through its distinct modes:

Intelligent Harmony Mode

In this mode, the pedal analyzes your playing and generates diatonic harmonies based on the selected key and interval. This ensures musically correct harmonies that fit within the chosen scale.

Intelligent Harmony Mode generates diatonic harmonies based on your selected key.

Polyphonic Override Mode

When the POLY OVERRIDE button is engaged, the pedal functions as a polyphonic pitch shifter. This means it can apply pitch shifts to entire chords without glitching, similar to other polyphonic pitch pedals. The INTERVAL selector determines the specific pitch shift.

Moment Mode

The MOMENT button allows for temporary activation of the effect. When held down, the effect is active; releasing it bypasses the effect. This mode also enables sweep time control for smooth transitions between dry and effect signals.

Momentary Mode allows for dynamic, on-demand effect activation and sweep control.

7. Troubleshooting

If you encounter issues with your Intelligent Harmony Machine, consider the following:

• No Sound: Ensure all cables are securely connected. Check your instrument, amplifier, and power supply. Verify the MIX knob is not set entirely to dry.
• Weak or Distorted Signal: Check your instrument's output and amplifier's input levels. Ensure the power supply is providing the correct voltage (9V).
• Unexpected Harmony/Pitch: Double-check the KEY knob setting and the #/MIN/MAJ switch position. In Intelligent Harmony Mode, the pedal relies on accurate key selection. Ensure the INTERVAL selector is set to your desired effect.
• Polyphonic Glitches: While the Polyphonic Override Mode is designed for chords, extreme playing or very complex voicings might occasionally produce artifacts. Adjust your playing style or settings.
• Moment Mode Not Working: Ensure the MOMENT button is pressed to activate momentary operation.
