Hi Andy A quick question on the XS key to get the Soundiver OSX beta to load/run issue. Does it matter if it is a white or blue key? Or if a blue key will not do the job straight off can it be updated? I may have found another way round with an old 'Classic' NFR ('Not For Resale' - Emagic official promo copy) that I picked up way back. There is a piece of MIDI porting softaware available from Troika Tronix called Midi Bridge. Do you know or have any experience/knowledge of this software. As I understand you open in Classic and it will port/bridge from Classic across to OSX MIDI drivers on your MIDI interface. Let me know your thoughts Cheers Ludite
