Many of you ignored the ability to get different results from the same instrument. Even Melodica-Me, who said something about that at the beginning, left that aside downhill.
It seems that getting different sounds using mostly different instruments may rely on the easiness of getting those, rather than mastering the sound range of your instrument (which is obviously harder).
If a melodica would cost 10,000$ and not 50$, would your answers stay the same? I quite doubt it..
