Deane,
It is a little confusing, because I think you may be comparing the PA3 Pro 61, with the PA3 Musikent 61. The Pro has 400 styles on both the 61 and 76. The Musikant has 500 styles on both the 61 and 76.
It is my understanding, The Musikant is available in Germany only, and the Pro is for International distribution. Can someone correct me if I'm wrong?
In conclusion, from what I can gather, the only difference between the 61 and 76 Pro is 15 keys, a hard drive, the motorized tilt display, the weight (6lbs / 3.2kg difference), and about $300.
Corrections welcomed
