Thanks Gary. There is no revoice on the T4. I can change the voices via the mixer but when I go to Song creator to execute and save I get the "copyright" notice and as long as I don;t sump the song from memory I can play it but cannot save the revoiced version for later use. I only use them for store demos I can show the original file then the revoiced file using the SART and other far better Voices than that in the MIDI bank. For live work I just make an audio recording and we use the track and remove the piano rather than take the T4 on gigs. I guess I could do the same with in store demos just use audio files before and after.
