Okay, I haven't come across any Aardvark Q10 threads more recent than around 2008 - so I know this is a long shot, but maybe someone can help. My setup is the Aardvark Q10 (7.13 drivers), into a PC with Windows XP SP3. It's a dual core AMD processor, lots of RAM, and hasn't given me any problems in the 8 months or so that I've had it. The Q10 has been going strong for 5 or 6 years now. I'd been using Logic 5.5.1 up until recently, when I decided to give Reaper a whirl. So far so good with that one. So, when I pull up the Control Panel for the Q10, everything is acting normal. When I arm a track to record in Reaper, and select which input to record, that's where things get weird. It seems that either the interface or the driver is routing the signal for each channel "wrong". Basically what I've found it to be doing, after going through all the steps to figure out exactly what the problem is, is sending the input signal from a given channel two channels 'to the left', so to speak. So, when I arm a track and tell it to record input 5, it uses input 7 as it's source. Input 8 gets recorded onto the track armed to record input 6, etc. (Inputs 1 and 2 are getting rolled over to inputs 9 and 10 respectively - which are supposed to be the digital ins). Unfortunately, I just had to bail on a small recording session with my jazz trio tonight due to this issue. It wasn't immediately apparent what was happening, due to the inputs used being spread out across the eight. (Rather than using sequential inputs 1-6). At this point, after tracking down what was really happening I've tried: - Rebooting - Uninstalling Reaper, then reinstalling, making sure the ReaRoute drivers are not installed - Uninstalling the Q10 software, reinstalling - Reinstalling Logic 5 to see if the problem carries over to the other program (it does) - Removing the interface cable, blowing on both ends, and reattaching. Reversed. - Checking prices on the web for a shiny new Presonus interface :| One thing I'm not too certain about, is if reinstalling the Q10 software did anything to the drivers. It used to be a two-part install, and now with ver 7.13 (which AFAIK wasn't written by Aardvark, but reverse engineered by a user's group that managed to finally beat the source code out of Aardvark at some point) it seems a bit different. I suppose I shall try using the Windows Control panel to try to reinstall the drivers. [EDIT: just tried this, and it hasn't fixed the issue] Please, any other suggestions? If I have to stoop to a fresh install of Windows, then I will - I'd like to avoid that one though if possible. I'd also like to try to keep the thing running. I've had no other trouble with it, and am still pretty happy with the sound quality/functionality. Thanks all!
