Hi. I disagree, especially if you are just beginning and having trouble hearing the pitches. I've used windows media player to slow it down so I can hear the correct pitch, I believe accuracy is important. Especially when I compare the notes to the chord changes to analyze it.
However, I do understand why you would say try it in real time. Only because when you are improvising, you have to 'hear' something in your head and instantly play it. I believe you should eventually do it that way but when starting off I think it's ok.
Good luck,
