Problem with midi playback 2017-11-12 05:28 pm Hi everybody, I am actually going crazy because either the programm OR my computer aren't doing what I want them to do, and that's: Insert an Instrument Patch (f.ex. Clarinet) and simply GET a clarinet sound.Unfortunately this isn't what's happening: I insert an instrument patch, and nothing changes. Or I get the instrument I want to hear, and 3 notes later it's the wrong one again... Is there anybody who can tell me what exactly the problem is, or what I can do to fix it? Thanks in advance! P.S.: I attached the score I am actually working on. Curiously the problem occurs most of the time in the flute staff (with sounds like a clarinet) and in the clarinet staff (which sounds like a trumpet or a flute).
