Dear Uncle '74,
I have many patches using poly~. I often change the number of voices according to circumstances (computer processing power, other patches open) and I divide the output level according to the number of voices within the patcher loaded by poly~. To achieve this I have to set a common switch to set both the number of voices in the poly~ objet (with the "voices" message) and to set the divider (using a send/receive connection).
However this would be much easier if thispoly~ had an additional outlet for this purpose, telling the current number of voices.
