Hi Malcolm Thanks - particularly I don't want to go to an AST because its I'm finding it too convoluted 'shape wise' - processing beam groups inside tuplets etc. is a nightmare - music representations have had at least eight centuries of ad hoc extension.
I know Norman Ramsey and colleagues papers on low-level representations - I'll give them a re-reading. Thanks again Stephen _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
