I dnloaded demo before buying but cannot test as all demo patches immediately make sounds without beeing started (some really loud, the first start was a painfull experience).
My system is a Mac Pro 2008 / 32 GB RAM / 8800 NVIDIA, OSX 10.7.4 with all updates,
Alesis USB Audio Device installed for Alesis Mulitmix 8 and
Automap from Novation for Impulse 49.
Any idea, any help ?
