Zuki,

The Tyros3 styles will not work in other Yamaha arrangers...at least not yet.

I'm sure here are conversions being attempted, although, apparently, none have been very successful.

The Tyros3 is, however, compatible with styles from the earlier arrangers, such as the Tyros1/2 and PSR-series as well as third party styles.

I've been trying them in my T3 and they work fine.

Sometimes OTS may need to be changed.
