They all have their pluses and minuses, in my opinion..I would suggest that, while the action is out and being modified, that this is the time to do some voicing down of the hammers.."it's too loud" is the single most common complaint that I hear, and it doesn't matter if it's a Piano Disc or a PianoMation or a whatever. Most people want their player to be a radio, and it's just not feasible. As far the actual player, I am most familiar with the QRS-type systems(ConcertMaster and PianoMation). I was familiar with PianoDisc at one time, and found their software options superior to the QRS systems..but then..in my opinion, if any system is properly installed, the software options aren't as important..again, this is my opinion. I live literally down the street from QRS Blvd., but if any system is properly installed, it doesn't matter what the logo says on the controller. Your mileage may vary, but not by much.. roo(k)
