Hi Al:
Do you mean "all at once"?
Several of the EFFECTS windows have a RESTORE DEFAULTS button you can push, but you'd need to look in each effect window to get to each button.
How about UNINSTALLING, then RE-INSTALLING WavePad? I'll bet that would get all your defaults back in one fell swoop. Be sure you've still got your registration information handy, because UNINSTALLING will cause your computer to forget you are a registered user.
Note that I am not connected with the WAVEPAD Company -- these are just suggestions from one WAVEPAD user to another. Perhaps one of the WAVEPAD officials will stop by the forum and suggest a better way of restoring all the defaults.
