pub const HOLD_BEFORE: Seconds;Expand description
How long the stem must hold above the first share of HOLD_SPAN
before it last fell below the second share ahead of a rise.
Below A1 the window of one period is as long as the rise of a tremolo of 14 to 20 Hz, so the rise alone cannot tell the two apart. A gated note holds its level until its gap, and a fast tremolo never holds. On the generated sets 50 to 70 ms keep every repeat and split no sine tremolo; at 45 ms a tremolo of 14 Hz on E1 splits, and at 80 ms sixteenths on E1 with attacks of 19 and 23 ms join.
