I have been thinking about getting a Yamaha P115 for the lounge room later in the year just for piano practice, but now after watching this video, I am thinking I might get a Roland A 88 instead and hook my old laptop up to it.
As for the the software, I think I would rather buy this than and ultimate upgrade. I would buy it at the $200 dollar price point, as there is 40 odd pianos, so $5 an instrument is okay with me, not sure about $10 and instrument though when I have so many already.
I think Spectronics may have just sold me on a Roland product..
