I created about two dozens song styles with custom intros/endings (that I recorded as MIDI songs) on the T3.
These work great on T3. I load them in my S770 (bought 2 days ago) and most of them play intros/endings as expected.
There are 5 of them where the intros/endings melody are QUIET (not heard).
By looking at the style mixer, I found that the phrase1 and phrase2 channels (where the melody are recorded) do not have the instruments that I used to record them. A piano (
) picture is shown there instead. By changing this instrument to the original one I record with. The intro/ending melody is now heard as it should be.
Kind of strange. Look like I was using a voice (saxophone) that is on T3 but not on S770.
