      After a few days of testing and reading I'm starting to understand the power of OpusModus.  What would be beneficial to me (and perhaps other new users) is a collection of relatively simple scores.  I see references to such scores in the forums, but I cannot find them.  Perhaps they are not available in the newer versions of OpusModus?  Here is an example of a score I cannot find:

      dear all
      here is a setup for playing midi-files/scores in polytempi / follow the instructions and have fun!
      just ask if you have some questions...
      - personally i will use it for exact sample/e-player perfomance with my pieces which are working with "Technology-Assisted Conducting"
      http://polytempo.zhdk.ch ... in future i will do it all directly from OPMO or lisp - "live score generating" + polytempo-conducting + e-player)
      - i have already done this with my piece MODULAR FORM  but not all controlled by LISP/OPMO, so next step is doing it all in OPMO/LISP
      ...some explanations about the piece....

      Dear all,
      After updating to a recent Opusmodus version 1.3, I ran into some errors when loading code that had been loaded and compiled before, e.g., quicklisp, quicklisp libraries, swank (the interface that allows using Emacs Slime with Opusmodus), and my own Lisp libraries. The errors I saw were rather cryptic, like the following:
      Error: The value "CL" is not of the expected type list.
      While executing: (:internal ccl::operation-on-all-specs ccl::%define-package), in process Listener-1(7).
      After exchanges with Janusz (thanks a lot for your help!) I learnt that the underlying Common Lisp version of Opusmodus had been upgraded to CCL version 1.12, and the format of compiled files (fasl files or dx64fsl files) of this version had changed.
      So, in case you run into similar problems, these can be fixed simply by deleting all previously compiled files (which Lisp stores if they do not change to speed up the load process), so that the Lisp compiler has to compile them again. In the folder  ~/.cache/common-lisp just delete any folders starting with ccl-, so that all compiled files in this directory are compiled again.
