Old OS on Audya was some better because I can play when I use keyboard style and sometimes freez instrument-I hope new OS 42B fix this bug..but now is much worse...any time Audya Froze - few styles.I not have problems when i use MIDI files-on new OS play ok-old sysytem when I play some few MIDI`s he lost track- normal midi files have 16 tracks-when i play few times midi Audya play only 9 tracks (no bass and drums sometimes play only bass... )
