The Players of Pa-Keyboards are just players - nothing else. If Pa-Player select an SMF located on an USB flash, HDD, SSD or internal Drive (Korg Disk) of a Pa-Keyboard - the result always is the same: sounds are used according to that Midi-events in SMF that are responsible for assigning the sounds.steve350 wrote: .. I am using his midi files from a USB flash drive plugged directly into the front of my Pa4. Later on I am going to pick one of the songs that he said he put the factory settings on and load it into my Power Tracks program. That will tell me if indeed the factory settings are on those instrument tracks in his song.....
It also is not necessary to pick your songs for loading into Power Track - that also easily can be seen with Pa-Keyboards screen of Songplay Tracks with bankselect / program number in Format like eg 121.017.091 - that is CC00 (Bank Select MSB), CC32 (Bank Select LSB), PC (program Change). In case CC00 or CC32 is zero sounds are GM-Voices.

Your Pa4 does not play SMFs with GM-sounds or GM2-sounds instead of Factory-sounds - also your Pa3x did not play always with factory-sounds, but both Pa-Keyboards always in same manner play that sounds that are inside the SMFs. That are rules of MIDI-specification since more than 20 years.
If you do not want sounds as existing in SMF-tracks since there is no other way than to overwrite the bank select + sound programs in the SMFs with the sounds that you like best.
If you like to do this with Power Tracks you can make changes to the MIDI file and use "File | Save As" to save the song, so that you don't overwrite the original MIDI file.
But believe it: there is no difference playing SMFs with Pa3x or Pa4x, but depends what Midi-Events (Bank Select, Program Change) are written inside SMFs you are using (with Pa3x or Pa4x)!
