I haven't seen a reply - so thought I might drop a quick response.

The recording capabilities of the pro is the biggest difference between the models you were asking about. The way it was explained to me was that the pro has the capability to measure up to 1024 increments of key and hammer movement while the regular Mark IV is 256. The pedals will measure the distance the pedal travels by 256 increments versus the 128 on the regular Mark IV. The quality of the solenoids are superior on the pro also. The pro records all of the data in what is referred to as XP mode and that extra data needs to be stripped for a regular sequencing program to be able to work with the data. In other words - if you record on the pro and keep the data in the pro - you cannot find a better recording piano on the market. With the superior solenoids the playback is the 'most accurate' money can buy.

Hope that helps
