An Engine is essentially an independent entity with its own MIDI channel (they respond to channels 1-8), although the tempo of all the Engines is locked to multiples of Engine 1's tempo.

Each of Guru's eight Engines contains 16 pads that can be sequenced from your host sequencer using MIDI notes or controlled by the Engine's advanced step sequencer system. There are sequencers for Pads (the Pattern view) and for modulating certain sound parameters (the Graph view).

Each Engine also has 3 Aux effects and an Insert effect There is also a Master Insert effect which affects the entire Master output.
