Hi,I'm hoping someone out there knows what I'm doing wrong.I have a home studio setup with a Mac and I use Cubase. As I recently had an audio interface pack up on me and was also needing a mixer, I purchased the X1222USB as an all-in-one solution. The problem is when I attached the mixer to the computer via USB, and assigned the device, which shows up as 'USB Audio Codec', and then tried to assign my VST Connections for the input and output, it would only let me assign it to either one or the other, not both. I can either record with it or I could play back with it, not both.I did a little reading and found I could create an Aggregate device using Audio MIDI Setup in Utilities, so I did that, creating a device that included both the ins and outs, then within Cubase, assigned the aggregate device.But now, after successfully assigning both input and output to that aggregate in VST Connections, I get a horrible distorted signal. Even playing music in iTunes gives me a horrible hiss.I trust I have made a complete newbie error here. My hope is that my newbie error wasn't in buying the bloody thing.Any help appreciated.Thanks.

Hi, are you using two devices for audio?, doesn't sound like it. If not there is no need for a aggragate device. You simply need to make sure you have your USB device selected. VST is not supported at all in OSX. You would need to use a host server like Vienna Ensembles latest version to use VST.

All functions for audio and midi should be served fine by the core audio system.Make sure your USB device is chosen for the Mac for input /output and even for system sounds too. This is found in audio settings for OSX.Cheers,Tony.
