How do the envelopes work?
The length of the envelope is specified over 4 steps (one beat) shown by the vertical white lines. There are three yellow or greenish lines running vertically that control how the envelope is used for a note. The right arrow > specifies the beginning of the sustain period, the left arrow < specifies the end of the sustain period and the double bar || is the end of the envelope. If the note is the same length or shorter than the envelope (in the above case 4 steps) the envelope will be used straight through until the note ends. If the note is longer than the envelope length two things can happen: If the option is chosen the envelope is stretched out between the start and end of the sustain period. If the option is chosen the envelope is looped between the start and end of the sustain period. There are a couple of keyboard commands to help with drawing envelopes. Use "A" to average the envelope and "F" to step it (like the snap function in drawing programs.
