Individual Drum Faders: The ten faders between the Accent
and the Main Volume fader, control the volume of the drum
sounds, on the device. Most of the faders control one sound,
but there are also faders that control two.
For the faders that control grouped sounds, the grouping is
similar to the original hardware TR-707 / 727 devices.
Chapters 2.1 and 2.2 discuss the details, of the individual fader
names per device and sound groupings.
