FOAM’s interface is organized into five main cards:
CardLocationPurpose
Bubble PhysicsTop LeftHow bubbles emerge, pop, ring, and fade
Fluid Dynamics & AcousticsBottom LeftThe liquid medium and physical resonator body
EnhancersTop RightSpatial effects, modulation, and temporal dynamics
Pitch Gravity LogicBottom RightScale quantization and ADP psychoacoustics
Foam Voicing DynamicsCenter BottomVoice scaling and parallel compression

Header Bar

The top bar contains:
  • Preset dropdown — browse and save presets
  • MIDI Learn button — click, then right-click any knob to assign a MIDI CC
  • OSC button — configure OSC output (green when active)
  • CPU button — opens performance menu for threading mode and bubbles-per-second governor

Parameter Locking

Right-click any knob to lock it. Locked parameters are excluded from:
  • Chaos randomization (both Jump and LFO modes)
  • Drift modulation
  • Preset changes (locked knobs retain their current value)

Right-Click Toggles

A few controls have additional behavior on right-click:
  • Chaos knob — toggles between Jump mode (per-note randomization) and LFO mode (continuous multi-rate modulation). Label changes to “Chaos LFO” in LFO mode.
  • Any knob — locks/unlocks it from modulation as described above.
