The Smart Grid One synthesizer features a dedicated quadraphonic panning system for its 9 voices, allowing for complex spatial movement and distribution.
The panning system is driven by a single, global phase oscillator (m_panPhase). Instead of each voice having its own independent panning LFO, all voices share this global phase.
To ensure the voices are distributed spatially rather than stacked on top of each other, each voice receives a unique phase offset:
staticOffset). This guarantees that even with no user modulation, the 9 voices are spread out evenly across the panning cycle.PanPhaseShift parameter.The actual X and Y coordinates for each voice’s position in the quadraphonic field are computed by a Lissajous LFO (LissajousLFOInternal).
The Lissajous LFO takes the offset global phase and generates 2D coordinates using the following parameters per voice:
The resulting X and Y coordinates (normalized to [0, 1]) are then used by the quadraphonic mixer to distribute the voice’s audio signal across the four output channels.
