Week 1: Compiling and loading CLM instruments

There are a wide variety of instruments included in the CLM distribution. Feel free to experiment with different instruments; you are not limited to those presented in class!

• Most instruments on the list are included in the following directory (remember also that Fernando provides example instruments with each lecture, available from this website):

  /usr/ccrma/lisp/src/clm-2

• To start using a pre-existing instrument, you must compile and load it. As Fernando mentioned in class, this process compiles and optimizes the contents of the (run) loop so that it will execute faster (always a good thing). First copy the instrument into your home directory (if you want to save it) or into the /zap directory (if you want to delete it when you log out). From a terminal window type:

  cp /usr/ccrma/lisp/src/clm-2/piano.ins /zap/piano.ins

• Then run xemacs:

  xemacs /zap/piano.ins &

• From inside xemacs, open a second xemacs window and invoke the lisp interpreter there:

  c-x 2
  
  c-x l

• Then compile and load your instrument from the lisp prompt:

  :cl /zap/piano.ins

• To test that everything is working correctly, try the following command. Note that different instruments will have different names and different parameter lists -- "(p 0)" will need to be replaced by the instrument name and the parameter list in question:

  (with-sound () (p 0))

• When you're finished with the lisp interpreter you can use the exit to end the process:

  :ex

• Then you can exit xemacs if you're ready:

  c-x c-c

• For more information see Randal Leistikow's tutorial on this topic. Next: more information about (with-sound).
