Purpose

Modal synthesizes the resonances of a struck object. Material selects the resonator, while Size, Position and Hardness change how it rings. Held gates can scrape the object for a continuous sound.

Use

Place Modal from the Audio view of the Voro menu, under Other. Connect a MIDI, note-lane or control source to triggers and route out to your audio output chain. Choose a Material, then change Size and Decay while triggering notes. Raise Scrape and hold a gate to hear sustained contact.

Inputs and outputs

• triggers, required. MIDI events, note lanes or a control stream.
• out. Stereo audio.

Controls

• Material selects wood, metal, glass, stone, ceramic or plastic.
• Size scales the object. Higher notes also make the modeled object smaller.
• Hardness changes the impact brightness. Position changes the point of contact.
• Decay scales the ringing time. Inharm changes the spacing of resonances.
• Variation adds differences in size and contact position between strikes.
• Scrape sets sustained contact under held gates. Roughness shapes that contact.
• Gain sets output level. Spread places voices across the stereo field.
• Strike triggers a manual hit using Strikenote and Strikevel.

Notes

At MIDI note 60, Size of 1 uses the material’s reference size. An octave up halves the object size before the Size control applies. Velocity affects both the force and brightness of a strike.
