I guess I had a restricted view of Syntesia. I have to admit I know mostly this product by the video which are available on YouTube where none of the functions you cite are available.
Concert Creator has some useful function : speed, loop, but no wait after your note.
I mean by enhanced, the draw of the hand playing the keys.
Printing score from MIDI wasn’t a function I would expect from Synthesia. I see thus product more about a vertical pianoroll viewing.
Both product would need a PC tablet to be used efficiently… and I have none. Then I don’t think I would use them for a while.
