I recently updated my PSR 3000 firmware to the 1.80 version. It seems a bit off now. Is there a way to downgrade, or go back, to an earlier, stable version? And if I can, which version should I go to - I don't need the internet updates, b/c I don't use the keyboard's internet anyway? And where can I find that version?
Last question - is there any way to add totally new sounds to the keyboard(not edited presets)?
