Hi Magali,

As I said, if this software could add the Genos drums & voices to my PSR S770, I would have definitely purchased it.

The demo is free, gives you ALL the styles that comes ONLY with the most expensive elite version and is fun to play with. I REALLY like the added effects to many of the styles.

In my opinion the main advantage of this software is the ability to add more effects to the styles. (Plus of course 8 variations, 8 OTS settings, two Fills/Breaks, extremely easy style editing, the use of registrations etc) I would not attempt performing live with it - yes, I am sure it CAN be done, but it will not be easy until one gets used to it.

I also cannot pay a quarter of the full price of a new SX900 just for some added effects to some styles. As it stands the newer styles as lately available already put the PSR S series in a totally new category sound wise.

But I certainly enjoy listening to those effects. I think Yamaha relies very heavily on effects (they are masters in this department). Groovy Band Live makes the Yamaha guitars sound even more amazing!

For studio work this will be a nice option to have & hence the need for a style sequencer to be urgently added to the software. Ad to that a built in digital human voice harmonizer and then this would no longer compete with similar software arrangers but be in a niche of it's own.

The styles from Groovy Band live DO sound better than the default styles of the PSR S770 - I'd even say they sound MUCH, MUCH better and to achieve that must have taken quite some initiative. So I give the developers credit for that.

Thus it really might be the best sounding Soft Synth currently available even though it requires the Yamaha sound engine to do so. If you want studio quality sounds, you should seriously consider looking into this product. And nothing better than their free demo to explore all of this hands-on for yourself...
