I will try again looking for anyone that can help me with a Korg PA80 OS. Not the one for the actual PA80 OS, but one that lets the PA80 have 88 keys. The files are…OSPa.LZX BPa.SYS NBPa.SYS. Notice that the “80” is not included in those files. The files for the PA80 are, OSPa80.LZX BPa80.SYS NBPa80.SYS. I have those. Korg says they cant help me.
