Didn't know they used the 5.3 GB of streaming tech from Kronos... Good to know! Seems to be a toss-up between the Pa4X and Tyros 5. It should be interesting to see what happens since the music production guys at Yamaha took over the PSR/Tyros line. Montage and the S970 have the new processing chips... The <insert new name of Tyros here> should be a huge jump forward! Korg is pushing them with their jump in tech. Please... Add an easy to use linear sequencer with a bunch of processing, editable tracks, stereo polyphony, mastering fx, the list goes on... A songwriter and arranger's musical friend!!!
