Is what the attached patch what you want?

Well, but a known one and hard to get rid off. File system operations
by nature are not realtime safe. You could use readsf~ or writesf~
which have precautions against hickups.

See the [poly] help patch. Pd doesn't really know "voices" it is
monophonic by nature. If you need polyphony you will have to create as
many signal generators as needed. Some externals like dyn~ make this
easier.
