I have a song where I would like to put in what sounds like car horns honking. I want to be able to vary the pitch and duration of the sounds. So I'm thinking I could use my keyboard through MIDI. That would allow me to control pitch and duration. However, I don't know how to find a car horn sound to use for the track. I suppose I could use a trumpet or other horn sound, and EQ it to sound like a car horn. But maybe someone here knows a better way? Please note that I have no experience with MIDI sounds, so this will be my first attempt.
