Vast amount of exercises, poor sound

I like the sheer depth of this app, however the piano sounds bad. The guitar sounds worse. I have pretty good ears as I have used a great number if virtual instruments in depth. I am a very good mixing engineer. I am not a piano player, but I know what a real piano sounds like. There is key noise, resonance, reverberation, but this piano has none of that. It makes it very difficult to detect minute vibration gaps in any musical sense. I wish I could give this program 5 stars, but the instruments are simply pathetic sounding. The developers need to go back and record a real piano.
