The "<" and ">" statements are used to specify crescendo and decrescendo marks
respectively. Each mark must include a begintime and duration. Some examples:
1-2: c;d;e;f; < below 1: 1 til 2; 3 til 4.5; 3: 2c;g; > between 2&3: 1.7 til 2m + 1; bar 1-2: d;e;2g; 3: 2d;a; < 2,3: 2 til 3.8; bar 1-2: e;g;2c; 3: 2.e;4c; endbar
The placement of crescendo and decrescendo marks can be controlled by setting the dyndist parameter.
