8 mapped presets for the Synthstrom Deluge using it's in-built FM synthesis engine. Each preset corresponds to the according midi channel (FM1- Heaven's Gate = Channel 1 etc.). Think of these presets as starting points for you to destroy, soften, brutalise or do whatever that resonates with you. Just extract the folder and drag the presets into your SYNTHS folder on your deluge. You still need to 'learn input' the keyboard on the correct channel but the CCs are already mapped. That's it.
