A low-frequency sine oscillator that produces a control signal rather than audio: its single control output swings smoothly between 0 and 1, ready to modulate another block's parameter. Rate (Hz) sets how fast the cycle repeats, and Depth scales how much of the full 0-to-1 range the output actually covers.
The block reads a precomputed sine wavetable in reverse, updating its value at a reduced internal control rate and holding between updates; each engine tick advances the oscillator by one sample-frame, in keeping with WaveWarp's sample-per-sample engine.
