Does anyone know where I can find the original factory sounds for the Yamaha TX816 rack or where patches can be obtained? I've contacted Yamaha and have not heard back. I know the modules can be programmed by MOTU Unisyn and similar programs and the DX7 itself. But, are sounds available online for download? Can the sounds be dumped to the modules via sys/ex from a standard sequencer Pro/Tools, DP. Logic, etc. Appreciate any advice. I'm selling the unit and don't want to screw someone over when they buy it.
