The gong machine tightly integrates with your playing, it plays back organic sounding performances of the notes you feed it with. Some quite new twists make this possible: It plays back round robins, to start with, so the patterns have a natural feel. But it also plays all articulations and even nearest neighbour repitched versions of them. An inspiring tool.
The pedal control is the same as with normal playing, clamped articulations become open and vice versa, and with the mutate command it subtly or dramatically alters the played pattern when a new chord or note is received. You can recall patterns from the Browser and store and recall your own patterns. To create new ones there's a create menu with a lot of macro's for creating basic patterns and manipulting them. You can also use the Building block presets from the browser as a starting point.
