Roland GP-3 vs GP-6 vs GP-9 vs GP-9M Comparison Chart
Four digital pianos in grand piano cabinets, from the 2-foot-deep GP-3 to the GP-9M, whose keys move on their own.
Roland’s GP series puts a digital piano in a grand piano cabinet. The GP-3 is a compact mini grand; the GP-6 and GP-9 are full digital grands with Piano Reality Modeling and speaker systems built into the case; the GP-9M adds keys that move by themselves to play back performances. This chart compares all four.
The Differences in Brief
- GP-3: about 25″ deep, the PHA-4 Standard keyboard and Piano Reality Standard sound, with a 22 W two-speaker system.
- GP-6: about 38″ deep, the PHA-50 Hybrid keyboard, Piano Reality Modeling and a 100 W multi-speaker system.
- GP-9: about 59″ deep, the Hybrid Grand Keyboard, the Responsive Damper Action pedal and a 150 W system with speakers under a full-size lid.
- GP-9M: the GP-9 with moving keys, which play back recordings and lesson songs on the keyboard itself.
