If that (--enable-jack) is so I think you will find that the slider to
slow down the audio output is unavailable (on far right of playback
controls).

yes, that should not affect the drawing - if my reading of the code is
right then the number of transition steps and the time of between steps
needs to be settable by the user to adapt to faster/slower machines. As
I say, you don't need to wait for the cursor to settle before typing in
more music... the instant skip has already happened.

I don't know what people mean by that.
