I was told that Yamaha Motif grand piano sound was taken completely from PSR9000PRO. I would like to know exactly what is the relationship between those instruments. I am talking sound only.

Several sounds are from the 9000pro. The grand piano is one, sweet flute is another, the nylon guitar is another and a few more which I can't remember as a write this.

The 9000Pro is not a PSR as far as Yamaha is concerned. The Motif has 85MB of sounds, while the 9kPro has 48MB, although the Motif compresses the ROM sounds, probably so they fit in about half the ROM. I assume the compression is inaudible, it works for Roland. The Motif borrows sounds from a number of Yamaha instruments including the 9kPro, but also others. The 9kPro has a physically modeled organ, but I believe the Motif does not. A BIG difference is that the Motif reads Yamaha and Akai format sample disks, while the 9kPro reads only .wav and maybe AIFF, which are also read by the Motif.

The Motif is very cool !
It is not an arranger keyboard .
The sound are generated from the former EX5/EX7 workstation and also the current S30/S80 keyboards . The motif can syncipate samples to a midi sequence . The slider and knobs will control midi data . Knobs can control Cakewalk ,Steinberg etc.....
Easy to use .
I think Yamaha hit a home run ! Very cool keyboard ! Dan o
PS...Yes it has the 9000pro piano sample
