Getting the voice limit count

Question

I would like to query Wwise via the API to get the maximum number of voices currently set. I see SetMaxNumVoicesLimit, but there does not appear to be a get variant. Also, is there a way to set/get the max virtual voice count instead? The purpose of this is for initialization of a mixer plugin, where I'd like to pre-allocate objects based on the maximum possible number of IAKMixerInputContext objects that can be connected to the plugin at any given time. My impression is that virtual voices still remain connected as inputs, but are not processed.
