Hello there,
Just had doubts to use Wave Pad not in the right order but all effects and special effects work except the vocal removing one. Have the v3.03 Masters edition and recorded an original stereo sound (.wav) from CD but after marking the record and clicking on 'special effect remove vocals' nothing, really nothing happened - no pop up for parametering, no changin, simply nothing. But i need this urgent!!! 
Thanks a lot in advance for help
