Midi player with sheet music display for mobile devices

I require a iOS mobile app (iPhone and iPad) that plays midi files and displays the sheet music associated with the midi file. The app needs the following: * notes highlighted as they are played * ability to change volume/mute one or more staffs (midi channels) * ability to change instrument type for each staff (midi channel) * ability to fast forward, pause and replay * storage for files within app * quality interface design This project is a larger sized project and can be difficult for you to estimate accurately. If you are the winning bidder, I want you to finish it. To ensure you are fairly compensated on this project, I am following [login to view URL] Best Practices and using the "Hybrid Payment Variant". To bid: > * Read about the "hybrid payment variant" at [this link][1]. > * Describe to me, exactly what portion of the entire project you'll do for the trial portion only. > * Place your fixed-price bid for doing *just this trial* (and not the entire project). Remember, your bid must be less than $200.00 if you are from an emerging economy and less than $700.00 if you are from a mature one. > * In your comment, tell me how much per hour you will charge me for the remainder of the project, if you are selected. Note: I may choose to opt-out of this second stage if I do not like your performance in the trial. So be sure to give me your best work at all times.
