I have the (old) YAMAHA PSR-SQ 16 and PSR 500m. I connected the two by a MIDI cable in order to import stuff from the 500m to the SQ16. Still canīt get any result. I have the SQ 16 manual but not the one for the 500m. Can anyone give mea clue how to set up the conncetion and make things run? How do I get the music into the sq16 sequencer tracks?
