Tides automatically adapts its behavior at audio range to keep waveshapes musical and prevent aliasing

When Tides is set to audio-range operation, several parameters behave differently than at LFO range: SHAPE offers a different palette of waveshapes chosen for striking timbral contrast; SLOPE uses a linear scale instead of exponential for smooth pulse-width modulation; the range of SHAPE and SMOOTHNESS is narrowed at high frequencies to prevent aliasing; frequency multiplication mode uses different ratios corresponding to musical intervals. For clock-tracking at audio rate, Tides uses a phase-accuracy algorithm optimized for periodic waveforms.

Examples

Set Tides to audio range. Compare SMOOTHNESS response to LFO range — the range is narrowed. Use SLOPE as a pulse-width control for audio-rate PWM. Feed the output to an oscilloscope to observe the waveshape palette.

Assessment

Name four ways Tides’ behavior changes automatically when switched from LFO to audio range, and explain why the SMOOTHNESS range is narrowed at high frequencies.
