In the traditional rig, you can set up and save different combinations and channels: Clean, Rhythm, Lead, etc. Scenes allow you to create saved combinations within a preset. Scenes don’t rewire the rig or change what gear it contains; instead, they switch blocks on or off and change block “Channels.” Each preset contains eight scenes. Like presets, Scenes also have their own names.
Scenes also offer an advantage over presets when making sound changes while you play. When you change scenes, the FM9 does not need to reload the entire “rig.” Instead, it just sets the blocks and channels as needed for the new scene. This is not only faster, but also allows easy “spillover” of delay and reverb tails.
Channels on the FM9 make blocks extremely flexible. Each channel contains its own fully independent set of parameters for the entire block. For example, Channel A of a Drive block might be dialed in as a clean boost, B as an overdrive, C as a distortion, and D as a Fuzz. That’s four completely different drive sounds from just block. This can be used to conserve CPU power when compared to using multiple blocks.
