    Hi I have paid for this app and I have not received it. Why?
    Nowhere is it mentioned I have to wait but if so please give some type of detail in the check out.
    Please let me know what the hold up is.

    I purchased KeyChord to install on my Incredible – status in Marketplace shoes as purchased, but I am unable to get the app to install. Please advise.

    This problem can happen sometimes. It’s not related to the application, but to the Android Market app or the Android OS system. Most of the time this is solved if you reboot the phone and try again.

    Hope this helps!

    Is there any chance of including usb host support (via a usb host/on-the-go cable) so that we can connect up our physical midi keyboards to this great piece of software?

    Superb app by the way!
