IT IS NOT A TOTALLY SMOOTH GLIDE.
Again, I never said it was. I simply said that slurs can be done without hitting the partials between the notes, which is absolutely true as shown by the example I posted. You're the one who compared it to a smooth glide or synth portamento, not me.
I have to say I'm baffled why you'd even bring up a thread from months ago on a completely unrelated topic. I'm not interested in debating it all over again, the old topic is still there if anyone wants to go read it. But if you're going to put words in my mouth I'm going to correct those falsehoods.
