It's a very interesting task what you are proposing, not only because of the involved technologies, but also due to the exciting tools it provides to the professional and the amateur musicians, to which I belong myself. I will try to outline here my ability for this job so we can talk about it more deeply.
I have been programming with C++ since more than 15 years in the most various sectors, always with the main guideline of producing code that combines in the best possible way solidity, clarity and efficiency, as these components are all essential for the operation and the maintenance of software. In the multimedia area I have written specialized video and audio tools handling most major encodings and containers, and dealing with the challenge of managing huge streams of data in real-time. At the musical level, I have designed an dimplemented among others a music editor (see Portfolio) able to read MIDI files and to playback using the VST instrument sets von Steinberg.
I understand you need some securities before starting such a job, and so do I. Unfortunately I cannot show you the code of the aforementioned tools because it is private, and that wouldn't in fact give you any real warranty, but we can do it another way: let's start with some very punctual assignements on points that are for you significative (they can be quoted as a simple preambles), and so we will quickly see if it's worth talking about a long-term collaboration.
