I also get a very high load. I will need a bit time to take a deeper
look, but generally the data structures are far from the efficiency
that e.g. Gem has. However I don't think your model should be that
slow.

Yes, and it even works better here (maybe I have another sprintf, I
get lots of errors like "sprintf: no method for float").

Anyway the solution is to replace every "sprintf" with "makefilename",
you can keep the "pd-%d-data" part, it's the same for makefilename.
