Be warned: If Spectre has internet acess, it offers to download the 1.5 update. This update does not work here, I am currently without Spectre. And I am not the only one. Error messages about failed interface initialization and no signal in Spectre. There is already another report in the Spectre forum, unfortunately without system information. I have a MacBook Pro and OSX 10.5.8. Interface is RME Fireface 800.
