The problem is that it does not have the Onyx firewire card optional. So I am embarrassed I broadcast the sound through MaxMSP or Puredata and broadcast on every channel and the type of information you want on each. is ultimately a different sound on each hauparleur. Is this by chance an interface as the RME Fireface could solve this problem I encounter to assign each speaker a different sound. and thus control chaque effects or sounds from MaxMSP and PureData. Thank you in advance.
