You are both pretty close though the stage piano used here is the YAMAHA P80, which was manufactured in 2000/2001. It was a budget stage piano retailing at approx. 600 euros at the time.
It has a full 88 graded hammer action keybed and plays like a dream. It has two line outs and two headphones out. Most amazing of all is that this piano which also includes a number of other sounds a.o. a lovely DX/whithey houston electr. piano sound, has a total ROM sample memory of 11Mb. (!!!!!!!!!!!!!!!!). Personally I find that astounding. In all fairness I should add that I made the recording that you can listen to by putting two mikes in front of the Creative T10 speaker set that I normally use with this piano. by contrast, recording the sound via the line out straight into the mixing console it sounds considerably less................
Anyway, seeing we are discussing the merits and drawbacks of multi Gigabyte keyboards like the current discussions on PA4X versus T5, etc. I thought 11Mb would be "refreshing " to even contemplate
