you can do it with the TS404. use the slide thing..

when you open up the keyboard display for the 404, there is a row at the top, you click on them, and a little triangle appears..

I assume u mean the big pain roll thing that comes up...

but other than that I am not exactly sure what u mean...

do you mean those little color things that make the notes u choose different colours?

And this wee triangle I have seen it in some of the notes I put on, but I dont here a roll between note pitch changes...

I don't know, I'm no expert.

the piano roll confuses me, I don't use it, I just use the keyboard display, yes the pain in the ass one.

you put a triangle at the top of the notes, and they will blend together.

Here, take a look at this, it will help
