I've created a cubase instrument definition for the PA1000 (all programs), because i couldn't find one in the net.
User and Local is in there too, but only as an example (only bank 1, program 1)
Install:
Open %appdata% (explorer), from there browse to "Steinberg\Cubase 9.5_64\Scripts\Patchnames" and copy the txt-file to this location.
If you dont use 9.5 browse to your cubasefolder.
In cubase open the midi-device-management and install the device (Pa1000Programs (Korg)). Select the midioutput and close the window with "ok".
Now you can select this device in the inspector for a miditrack to get access to all programs by names.
Have fun.
Edit:
angelitto did some additional work. UserPrograms are selectable now. File is updated. Thx angelittoUser and Local is in there too, but only as an example (only bank 1, program 1)
