We at idvance LLC are proud to introduce version 2.1 of iTrumpet.iTrumpet is for people who play "real world" trumpets, not for the casual gamer:nnA. iTrumpet does not require you to blow into the iPhone microphoneYou blow a real trumpet using a range of mouth positions.We have deliberately chosen not to require confusing alternate behavior for your lips and tongue we see blowing into the iPhone microphone as an awkward gimmick, not as a practical design point.nB. iTrumpet does not require contrary fingeringYou play iTrumpet like a real trumpet, using your right fingers to press keys.To control embouchure, and to get open notes, you use your left thumb which is idle when playing a real trumpet.nC. iTrumpet simulates a B flat transposing trumpet with a full three octave range and with respectable sound quality for a simulator.nnWe designed and tested iTrumpet with experienced trumpet players.We believe that if you are a student or a professional musician, you will find our solution most compatible with how you play your real world instrument.If you are in a marching band or a jazz ensemble, give iTrumpet a try.Then email us at info@idvance.com, and let us know what we can do next to make it even less of a crude alternative when your primary instrument isn't handy...
