If you can’t get any MIDI files to make sounds in Fruity Loops then read on. There’s several points why no MIDI sound in FL Studio can happen. When you open a midi file in FL Studio you will see the different channels in the step sequencer.
1: Select the first channel by clicking on it and it will open up with the Channel Settings – MIDI out window.
2: In the Channel Setting window select Port 1 and leave everything else as default.
3: Now go to the mixer by pressing F9 and on the master channel open the plugin Fruity LSD.
