Decent sounds, but needs core MIDI support

I bought this app 2 years ago for $4.99 after being blown away by the Jordan Rudess video. I play sax and electronic wind synthesizer and thought it was cool for iPhone and with quality tones. The Tuba did not sound realistic but the others are good. Please update with core MIDI capability in order to make it useful for performance. Then I can use a MIDI wind controller to drive the tones. The keyboard interface is not practical when trying to blow into the mic because you have to strain to see where your fingers are touching. This doesnt work for performance or reading music. I see now that the newer WI Orchestra has added MIDI support and it works with a wind controller via iRig MIDI interface, but I shouldnt have to buy the same instruments again in the different app just for MIDI. The selection of these 15 instruments is a good choice and would be useful for live performance with an update.
