Has Yamaha's P120 action been changed?

I spoke with Yamaha parts department today and they informed me that the P120 "Graded Action" assembly (old part number V7803300) has been "superseded" by a new part number V7803300, which is also the same part number for the "Graded Action" found in the P90. I own an older P120 and a new P90 and the actions do feel different. The P120 action makes a harder thump sound when the keys bottom out. The P90 action takes less effort to play.

old a part # V7803300

So I now own a P90 and a P120 and I have been comparing playing the "Grand Piano 1" of each back and forth. The P90 is easier to play. The key to note connection is somehow easier to trigger and I don't know exactly why that is. The P120 keybed feels harder when the keys bottom out, the P90 feels a little bit more cushioned, the hump they make when the key hits the bottom is different.

 

The P90 notes sound rounder and don't have such an exagerated atttack portion of the sound as the P120. Therefore, on the P90 it's easier to execute fast runs that sound smoother and more connected. The sound of the P120 GP1 is more open, less round, more percussive,, more spacious; single notes sound bigger on the P120. The P90 GP1 tone is smaller, rounder, more muffled which is partly why it's easier to connect and blend the notes. The middle range of the P90 keyboard is softer and blends chords more together than the ouder more percussive mid range on the P120. The P90 sounds boxier in its mid range, sort of compressed like Kurzweil.

 

The P90 GP1 reminds me more of how the notes blend so well together on the P250, they integrate together well, connect more smoothly on fast runs, and have a "roundness" and a less steap decay curve. The P120 GP1 notes seem starker and more individual, they don't seem to blend together as well and it takes more effort to play the P120. The P120 GP1 pkays more like a "rock piano" or "fusion piano" and the P90 GP1 blends more like a "classical piano" or "jazz piano"

Mr. Martin, any update?

What is the question? If the parts department has said that the replacement part has changed then I'd take their word for it. As for the difference in feel, I personally haven't noticed it.

Just a change in part numbers. Its the same action.

 

The P120 action makes a harder thump sound when the keys bottom out.
This is likely just due to the difference in the enclosure.

 

To clarify, the P90, P120 and P250 all have the same key actions.

Is there a difference between the sounds in the P90 and the P120? I've only played a P120 and really liked all the sounds, especially the inclusion of great EP and clav sounds. The lack of clav in the P80 made me shy away from it.

 

Thanks,

Eric

Yes, the sounds are different. The second post on this thread describes some differences between the Grand Piano 1 on each model.

 

More than half the sounds on the P90 are in mono, and I prefer them. The only thing I miss on the P90 is the P120's EP2. The mono EP2 on the P90 is good for chording, but not nearly as good for single note solos as EP2 on the P120.

 

I have been playing the P90 for the last couple of days without problem. I played scales on the P120 for an hour today and now my wrist hurts. It takes more percussive effort to play the P120.
