New filter and effect controls for XM modules
=============================================


Filter Controls - Qxx

  QEA      Enable Filter Controls
  Q00..7F  Filter Cutoff 0..127          (equivalent to IT's Zxx)
  Q80..8F  Filter Q (resonance) 0..15    (equivalent to IT's Zxx)



AWE Effect Controls - Uxx

  UEA      Enable Local Effect Controls  (each channel separately)
  UEB      Enable Global Effect Controls
  U00..64  Reverb Level 0..100%   (in hex)
  U70..77  Reverb Type Index 0..7      (global setting, not implemented yet)
  U80..E4  Chorus Level 0..100%   (in hex)
  UF0..F7  Chorus Type Index 0..7      (global setting, not implemented yet)

  All effect level changes apply for new notes only.
  Effect type changes apply immediately for all channels and voices.
  Once selected, the mode (UEA/UEB) can't be changed later in the module.
  Defaults are taken from the panel in all modes.
  While replaying in global mode, effect level changes from the panel are
  applied immediately.

  NOTE: Due to hardware limitations, the LMP clone does not support a local
  control of the chorus effect - the chorus level is equal for all channels.

  Please keep in mind that the effect controls are meant FOR PRIVATE USE ONLY
  (tape mastering etc.) because they violate the major advantage of modules -
  hardware independence.
