Hi Scott Yes. I wanted 'Echo Piano', one of Mike Martin's tones as I play in a Pink Floyd tribute band. It's onmy data editr left hand column as a .ZTN file under melody tones. However, when I try and drag it across to one of the slots on the right, I just get: File Format Error EchoPno.ZTN. The same happens in the stage setting section for ZPF files. In fact, the only file I've had success with is Mike Martin's 'On The Run'. Sorry to be a pain, but can you think of anything I might be doing wrong? Andy
