564409 Android audio APP needed.

I'm looking for an app developer to create an android audio app. The idea is pretty simple and should be able to be built using existing code, nothing ground breaking here. Programmer will need to sign NDA before specific details are given. The app will basically be a "softsynth" that works as a "pcm synth". app needs to read .pcm files. App will need an option to "get more sounds" and be directed to files they can download. All sound files will be supplied by me. Please google "PCM synth" to learn more about it. An example of what I need can be seen in the "caustic" android app available on the market, however, I do not need a drum machine or sequencer etc, just the PCM synth as a stand alone. Needs to have midi export, mp3/wav recording function. Any social media features would be great, twitter, soundcloud etc. I need someone available on Skype during American business hours that SPEAKS ENGLISH. ALL CODE WILL BE TESTED AND VERIFIED BY 3rd PARTY.
