Digital Audio Workstation - DAW

Looking to overhaul our existing product into C++ and create device versions. In short, you will be programming a DAW (Digital Audio Workstation). This means you understand audio production, DSP, C++, VST's, the various SDK's and libraries/classes that are needed for audio production development. Will need 32 and 64 bit, mac and pc versions (and linux if possible). You will need to show previous work that is related to this project. Please do not bid on this if you have no experience in audio production products or will be learning as you go and showing me your website examples as samples... I don't expect you to have built a full out DAW before however you'll need to show and prove that you can do this with confidence, won't drag the project on for a year (we unfortunately have experienced this with a few programmers now), and have a solid communications system with your clients (me) at each step of the project.
