I did a tiny bit of DSP and I've been exposed to the HCI/NIME community in the past, but that's it. Many modules in the Anyma are just reasonable implementations of clever formulae I didn't design but studied from papers :). And for the Mutable stuff, a lot of optimization work and tradeoffs to make. We are lucky to have a sound designer with a good ear. That said, we've been working for a while on our own waveguide models (Windsyo and others), and we have found some tricks I've never seen elsewhere. There's a lot to explore, especially when looking for "hybrid" acoustic-electronic sounds.
