I surely hope that your proposal will be heard. Those would be essential
additions to vanilla's [poly] for polyphonic instrument building.
As for the [bag] object i tried but in the way i built the patch it only
works if the sustain pedal is pressed before note on arrives. I have to
find a way to make it work the same way when is pressed after a note on.
The same note retriggering is another essential feature.
