Thank you Sokratis,
that's all I needed to know, and of course I guess that also the audio guitar tracks are impossible to open... however, once you record the drums and the guitars to your PC (using the SPDIF out like you suggested) you can edit them and finally copy the new style to the Audya and save it like a user style, right?
By the way, I liked your songs, and I love Bebel Gilberto.
