Record a song on PSR S950 as SMF

[hayseed]

Hello All
Is there a way to record a song on PSR S950 ( I've done hundreds so I know how to )  but I can never play them successfully on any other midi device without a bunch of gongs and whistles and clicks that don't belong there , I've tried the Midi Mega voice Cleaner and it does not do the job very well.  I don't need anything real complicated   Just Drums, Bass, piano, accordion.
One shot recording and export the file to play in another GM device. Mainly an Ipad running Sweet Midi which uses the roland soundfont.

I also have a PSR 443 (I was  wrong It is the 423 )    which may be easier to record.
Thanks
