"have a canned intro both meld seamlessly into the style and be pitch adjustable - is not possible"
OH YES, iIT IS POSSIBLE, alll ryhtms that come with Tyros3 have intros.
And I have lots of rythms created (by others) for different songs, and their intros are incorporated as part of the rythm as well.
So when I start this intro, the entire intro is played in whatever key (based on the chord) I start with.
And it is clear that if the intro is created for a major key as the song is in major key, playing the same intro with a minor key will sound VERY ODD and of course I don't do that. And an intro created for a minor key song, playing with a major key sounds ODD.
I can play intro LIVE (which I do most often), but it will not sound as rich as a short song I recorded with more tracks added afterward.
That is the main goal, make the intro sounding rich.
Reading many tutorials in this Website, I guess, the proper method would be to used a software running on PC to merge the short MIDI intro in the rythm.
If this is correct, I like to know which software and how to get all this done.
Many thanks in advance.
