# configuration:
# - things like calibration data live in ~/.stepmania-5.1/Save/Preferences.ini
# - GlobalOffsetSeconds = difference between audio and video delay.
#   Hit F6 twice in-game to being auto calibration
#   Usually the result will be negative (i.e. the higher the latency of the pad, the more negative the offset)
# - SoundDevice: use pacmd list-sources and select alsa_output.pci-xxxxx
# - VisualOffset: if video is coming LATE, then use a negative number
