Tides uses FREQUENCY for overall envelope speed and SLOPE for attack-to-decay ratio, not separate attack/decay knobs

Unlike classic envelope generators with separate attack and decay controls, Tides separates two independent dimensions of envelope shape: FREQUENCY sets how fast the entire envelope completes (the total duration); SLOPE sets how much of that time is spent on the ascending segment versus the descending segment. Changing FREQUENCY changes attack and decay together proportionally; SLOPE changes their relative proportion. A common misconception is that FREQUENCY maps directly to attack time — it does not.

Examples

Set FREQUENCY to a medium rate, SLOPE at noon (equal attack/decay). Turn FREQUENCY clockwise: both attack and decay become faster proportionally. Turn SLOPE clockwise: decay gets longer relative to attack, without changing total duration.

Assessment

A learner sets Tides to a 1-second total envelope but needs a fast attack and long decay. Which control addresses the attack-to-decay ratio, and what happens to the total duration when they adjust it?
