Roel,
when you play the Tyros you have first to set the Equalizer and the compressor to the right values; then you have to try the styles together with the multipads, which add a lot of realism: they work like the Ketron sampled grooves but the sound quality is much better (all the sounds are sampled at 44 kHz or more). I advice you to try all the "Ballad" styles and -if you think that the Tyros lacks drive- try also the "Dance" styles, but first press the "OTS link" button, to hear each style with his pre-programmed sounds...then you will tell me
