I am looking for a skilled developer to build a web/mobile app similar to Synthesia. The app needs to be compatible with web, android, and iOS platforms. The core of the app is the midi player. It will need to be able to: -take a midi file and generate the "dropping notes" (see image), -generate sheet music. (User can swap between sheet music and falling notes) -play left, or right or both hands. (Pulling the information from the midi file.) -user can slow down or speed up (0.1-2.0x). -show the lyrics in "karaoke-style" (so user will know when to sing the lyrics as well) -It will need to be able to choose different sections of the loaded midi file to play at a time, and be able to swap between them. This is how the user will change the difficulty levels. The midi player is the heart of the program. The admin console must be able to create users of various membership levels, including how they pay for access. admin will need to be able to add more midi files, and adjust images, names, and details, about the song chosen. Users will need to be able to select the song from catalogues, and change options before starting. Specific features and functionality are required for the app, but I am open to discussing options and ideas. The app needs to be completed within a maximum of 2 weeks. I have someone working on the wireframe for the app pages now, and the designs. We can begin on the midi player concurrently, and work on the other pages after they are ready from the designer. Ideal skills and experience for this project include: - Proficiency in web, android, and iOS app development - Experience with building similar music-related apps - Strong UI/UX design skills - Ability to meet tight deadlines and work efficiently If you have the necessary skills and experience, please submit your proposal.

@WhizPool

Hi, Okay, so here's my honest opinion. I might sound expensive, but i am not. 1st of all, you will need a team to build that, because, no matter what, a single developer cannot do it all because of backend(Node.js), Frontent web and admin(React.js), apps(Native or React Native or Flutter). So you will need atleast 3-4 persons to do the job. Secondly, there's no way for it to be done in 2 weeks. It will take 2 months. If that sounds okay, let's discuss in detail including wireframes. Thank you, Zeeshan
