Hi Tyron,

You can download the Sonar 'Tyros Instrument Definition file' here:

Here are instructions on the procedure of installing it into Cakewalk-Sonar:

I also recommend you join us at Simon's terrific new Yamaha Users Group Forum (which includes at Tyros specific group as well) at: http://www.svpworld.com/forum/

Good luck.

Scott
