OVERALL OPINION

I have a PSR 640 for 5 years and he follows me everywhere: in concert, in my apartment, friends to set the mood and make thanks to karaoke disks with files noon.
I think the more of this keyboard is, when you want fun, the opportunity to play along with the demos (which are also quite nice) by selecting the part you want to play removing a particular track, not to mention all of the sounds that are surprisingly faithful (especially the sound of guitars always difficult to return).
Its price is now very affordable given the quality of the arranger.
If you need to make a choice, take the PSR640 is a gem of a music lover.

For CHARACTERISTICS see prcdant post.
It's just a complete instrument trs, if I remember correctly established in 1997.
Using the Yamaha range, which provides much ^ ^

UTILIZATION

As for the configuration of the instrument, it's like a big box in which you would have a keyboard, a sound module, a multi-effects complete a squenceur and a good old floppy. .. While the doc is typical of Yamaha (unclear) but it always ends up thanks to navigate the key ACCS fast. The sounds and rhythms are said to be good quality trs easily, it's a real pleasure ... Just a quick BMOL for squenceur and diskettes that are a bit '5th wheel carriage "and that the interface is not working trs. I put 9 / 10, I'm still bleuff by the quality of samples, especially synthleads.
