The PCM 70 Ver 2 & Ver 3 have completely different Preset Registers. Many upgraded to Ver 3 to gain the Inverse Room algorithm but lost the coveted Ver 2 Preset Registers in the process.
These are the SysEx register dumps from both Ver 2 & 3 for all to enjoy.

Use a SysEx utility to send them to the PCM 70 Registers.
