Rikki,
The P121 has an octave shift feature that most 88s don't have. (so, you actually get MORE than 88 notes available) I like having mine shifted down an octave, so I can remain seated in the center, but play the lower tones that compliment my vocal range better. If you take it out of the house - the 121 fits width-wise in the back seat of a mid sized car (Ford Fusion, for me). SO much easier to transport this way, and a better fit on stage in almost all setups I encounter.
The 121 has weighted. graded action, but it's ;lighter than some of the big boys. I think it's just about perfect for most players. There are so few times I would ever play the extreme notes on an 88 keybed. I never miss them.
Thank you Dave,
That does sound like an option ,just set it an octave down, should I happen to find a tune that needs that lower note. Probably not likely. Mine won’t be leaving the house, but still handy to have something I can move around myself.
So keys are still weighted, but not as heavily as some, but still gives a piano feel?
Thank you Dave
