[CM] Common Music and Csound 5

[Michael Gogins]

I will undertake a Lisp or Scheme binding for Csound 5 so that the Csound API can be called natively from Common Music.

Before I do this, I would like to know which version of Scheme or Lisp I should target. I will be doing the development work on Windows and Linux. Rick Taube's book comes with CLisp for Windows and this also can be used on OS X and Linux, so I would guess this is the best target.  CLisp runs Common Music just fine on my PC. 

I do not have time to maintain multiple bindings, so I need to know the best compromise.

Unfortunately, the most mature SWIG facilities for Lisp are actually for Guile and MzScheme (both Scheme). On my PC, Guile does not run and building it requires many dependencies, which I can obtain if consensus favors Guile over CLisp.

As part of this work, I will be moving the C++ form of the Csound API from the CsoundVST project into the Csound API library proper, and also moving the Python wrappers. 

This will NOT introduce any additional dependencies in the Csound API library build except for SWIG, and I can book in the generated wrapper code so that even SWIG is not required for the normal build.

Please advise me which is the best version of Lisp or Scheme to use for Common Music and the Csound API.

I would like to finish this work before Csound 5 achieves release status.

Thanks,
Mike
