Hi,
I studied electronic music composition at the graduate level and have been using Pure Data and Max/MSP (among others) on and off. I used to make complex audio systems using Pure Data back when I was an undergraduate student, but that was a long time ago. I still haven't lost touch and I'm still actively doing research in DSP, although I'm rusty with Pure Data (can pick it up easily).
If time is not limited, I am happy to help you with this project. Before you accept my offer, let us thoroughly discuss this.
