jochen, ChucK is case-sensitive, however recently many of the ugens were changed from e.g. sinosc to SinOsc to fit in with the existing ugens that already had that capitalization type. The old all-lower case ugens were kept so that older code would still run, but they are deprecated. In any case it sounds like you have an older chuck version, from before the ugen capitalization was changed. It would be a good idea to download and install the newest version, available from http:// chuck.cs.princeton.edu/. You can find out the version you are currently running with chuck --version. The most recent version is 1.2.0.7b. If you've already downloaded the newest version, it could be that there is still an older version of chuck in your PATH somewhere. spencer On Feb 9, 2007, at 5:57 PM, jochen lists wrote:

hi i am really sorry for this ultra-idiotic question but for some reason it is driving me nuts... i am running chuck from the command line on os x.

when i try to run a patch like this:

SinOsc S => dac;

the compiler complains about: "undefined type 'SinOsc'"

So typing that in lowercase works.

So when I want to do this:

SinOsc s => LPF f => dac;

SinOsc works when i use 'sinosc' (all lower) but no matter what permutation of LPF i try it just doesnt work... Could this be that something is screwed up with my path? Is it not able to find that Ugen ?

I am lost

Thanks for all the help ! - jochen
