   7          This is a driver for the guitar amp, cab, and effects modeller
   8          PODxt Pro by Line6 (and similar devices), supporting the
   9          following features:
  10            * Reading/writing individual parameters
  11            * Reading/writing complete channel, effects setup, and amp
  12              setup data
  13            * Channel switching
  14            * Virtual MIDI interface
  15            * Tuner access
  16            * Playback/capture/mixer device for any ALSA-compatible PCM
  17              audio application
  18            * Signal routing (record clean/processed guitar signal,
  19              re-amping)

  29        help
  30          Say Y here to add code to measure the impulse response of a Line6
  31          device. This is more accurate than user-space methods since it
  32          bypasses any PCM data buffering (e.g., by ALSA or jack). This is
  33          useful for assessing the performance of new devices, but is not
  34          required for normal operation.

  36          If unsure, say N.
