I am using Version 25 on a windows 10 machine. Recently discovered that MIDI files won't play when uploaded onto a keyboard via USB. Never had this problem with other versions. Project is created using set-up wizard, saved as a .musx document then exported as a MIDI file onto a thumb drive. When uploaded onto a keyboard (the same thing happens with 2 different keyboards) the song title appears but when I press play there is no sound although the metronome light flashes the beat and in Media Player the progress bar moves left to right as if the song is playing. Wondering if this is a glitch in 25 or am I missing a MIDI step somewhere. I've been creating projects the same way for several years with no problems until now.
