i am a HD400 user ..is anyone ese having the following problem?? i just installed the flash memory and HD400 EDIT updates..after the installations are over, all of the tones that use the volume pedal have gone mute!!! only the ones that use wah pedal are still fine.! wtf :O after a bit of tweakin around , i found that the two knobs at the volume pedal in the edit software that is always set with the MIN being at minimum and the MAX being at maximum is what is creating this..if both the knobs are turned to maximum then the patches become audible again!! BUT..with this setting, the volume pedal becomes ineffective as it duzn matter whether u press down the volume pedal, the volume remains the same!!! so...  WHAT THE HELL HAPPENED HERE??
