pub fn lfo_tempo_rate(
index: u8,
mode: TempoMode,
beat_rate: Hz,
) -> Result<Hz, RangeError>Expand description
The rate of a tempo-synced LFO.
Index i of lfo_N_tempo (0 to 12) gives 2^(i - 8) cycles per beat,
times the mode factor, times the beat rate. Index 0 freezes the LFO at
0 Hz. At 120 BPM the beat rate is 2 Hz, so index 8 (1/4) runs at 2 Hz.
