Sound Generation
The Gen (Sound generation) button is used to generate random patch settings. To generate
a new patch click on the button and some or all of the current parameter settings will be
changed to new settings. The Gen range is set on the Alpha's options panel described in the
next chapter.
Undo / Redo
The next two buttons allow to undo (and redo) parameter changes. Sometimes when editing
a sound you may accidentally change a parameter or not be happy with the sound you
created. If you only changed a few parameters it might be easiest to undo these recent
changes. You can do so by clicking the Undo button once or multiple times.
In case you went back to far, having clicked Undo once too often you can simply redo (that is
kind of undo the undo) the last change. Note that you can redo as many times as you did
undo before.
Note: complex operations like loading a new sound cannot be undone.
