The bell instrument in the Amsterdan Catalogue is not the same on Dodge's
book (Risset). Looking the orc and sco files below I cannot understand why
the size of f2 MUST BE 8193. If this value has the same size of the sample
table the result is a multitude of bells. I also did not find anything, in
the csound manual, about oscil1 that could justify this value.

orc (basic algorithm).
