Description
Time by which each tone will be delayed when using tone delay
If you've selected a Structure Type of 2–10, the output of tone 1 (3) and 2 (4) will be combined into
tone 2 (4). Thus, the setting of tone 1 (3) will have no effect.
(Thirty-second-note triplet),
(Dotted sixteenth note),
(Whole-note triplet), (Dotted half note),
This controls the sound generator parameters of the current part. It is a convenient way to use
randomness to create sounds you like.
This is valid if "UNISON" is on.
It produces a detune effect or a harmonize effect.
