we are not working on them at the moment (as none of us actually uses Csound). I know that Bernt got some of the Trills, not sure if he is planning to do anything related to them + Csound ... anyhow a good starting point, without having to write any Csound opcodes, could be to use the OSC interface I created, available here. This is a stand-alone program that manages Trill devices and that you can talk to via OSC. It has examples for interacting with it from node.js and Pd. Maybe that could be a good starting point for Csound? I am also happy to support anyone willing to write a Csound opcode (There are some Supercollider ugens here that may serve as a starting point).
