I’m have similar problems with other libraries in OM 6.6.1, which prevents me from opening my old workspace. Here is what happens:
Error while loading the library OM-Spat:
“The variable osc is unbound.”
Moving Om-Spat 2.1 out of the folder, restarting OM.
Error while loading the library OMChroma: “Lambda list (value) is not congruent with lambda list (value object) of #standared-generic-function special-keyword-index 216E754A.”
Moving OMChroma 3.1 out of the folder, restarting OM.
Error while loading the library chroma-classes: “Undefined operator get-orc-source in form (get-orc-source (get-orc “add-a1”)).”
Removing all content of libraries folder.
Error while loading the library chroma-classes: “Undefined operator get-orc-source in form (get-orc-source (get-orc “add-a1”)).”
I could try hacking into the code, but there are no libraries left in the folder, and this still happens. Does OM 6.6.1 also search for libraries in the OM 6.5.1 folder?
Best,
Ruben
