Android expert wanted for musician app (1906786)

I'm looking for an expert Android app developer who understands music/audio production. For example, Reason 6, Ableton 8, etc... I have a few UI versions of this app already designed. I will provide a full writeup that will explain everything in detail, with picture examples. The first version will be a simple, basic version. It will allow users to record midi "actions/movements", activating pre-sampled sounds in the midi environment, or similar. These midi movements will be recorded into loops, and become able to be edited on a basic level, and saved. It will be a simple UI with 3 or 4 preset midi tracks. For example drums, bass, synthesizer 1, synthesizer 2. This version will not record audio. We are looking for someone who can also be a part of our team in the future. If you do a great job on the first version, you will continually be hired to do future versions with more complex features. We also will be willing to give a bonus, which would be a determined % of the profits. Meaning, you'd make an income from the app even when your work is done. To qualify for this job you must understand audio/music production and be a top level android app developer. Thanks in advance for viewing my post. Jeff
