FERRO.1

01 / Energize. Starts a deep, sustained bass field. Three pieces of metal are three voices. No sequencer: you play their attraction.

02 / Pull. Drag a mass left/right to move it through the stereo field. Lift it toward the back to climb octaves. Move masses together for a hotter, richer sound. The Hz display shows all three voice frequencies together. Touch a body to inspect its pitch for four seconds; it then returns to the combined view. These are simultaneous tones, not a single summed frequency. Root is the shared tuning.

03 / Press. Hold an empty part of the table to squeeze the entire field. Field controls the distortion and spikes; Inertia makes pitch glide. Pulse adds a shared heartbeat, Fracture breaks it into irregular bursts.

Keyboard: select a mass below and use its position sliders. Space on the table presses the field. Start at a comfortable output level.
