make it possible to disable MIDI playthrough (aka MIDI thru or MIDI echo)
It would be nice if the automatic echoing of MIDI input to the internal synth could be disabled without disabling MIDI note entry altogether. Finale has this option under "MIDI Thru". I prefer to use my MIDI keyboard's no-latency built-in piano sound when composing, and I must turn off MIDI input in MuseScore to avoid the doubled notes coming through the SoundFont synth. Sometimes instead, I'll just turn the synthesizer volume to 0, but then I can't hear any of MuseScore's playback. The only time hearing MuseScore play the notes is useful to me is when entering/editing notes or playing back the project.
