PC-6001 Mk2 SR also has an FM synth accessible in N66SR BASIC, specifically: Yamaha YM2203. It allows playback of 3 additional channels for FM instruments/sounds bringing the total to 6 channels of music playback.

Here''s a video captured of music playback on this computer that use both PSG and FM:$zvVq8MHoybA

Playing both PSG and FM was as simple as using the play command with 6 arguments: $PLAY "cde","fga","cge","@3cde","@5fga","@7cge"$
