Here''s a video captured of music playback on this computer that use both PSG and FM: https://www.youtube.com/watch?v$zvVq8MHoybA
Playing both PSG and FM was as simple as using the play command with 6 arguments: $PLAY "cde","fga","cge","@3cde","@5fga","@7cge"$
The "@" char is used for FM channels to specify instrument out of 12 preset instruments or using a custom instrument out of a few available slots.
