Why not trying to finish FaustGen: [WIP] FaustGen - a UGen for interpreting Faust code ?
Faust + LLVM JIT, lot of already written DSP :
- https://faustlibraries.grame.fr
- Faust examples by category - Faust Documentation
- Powered By Faust - Faust Programming Language
I can possibly help 
! (I have a fork here: GitHub - sletz/faustgen-supercollider: Livecode Faust in SuperCollider using an embedded Faust compiler.)
