I spent the last couple of days trying to get this software to work, It's not a hardware issue, I don't think. as I have a trial version of Sonar X1 which runs with no issues.
I have tried setting up GTPro3 the same way as Sonar with no luck.
I'm running a Digitech guitar processor via USB through my SoundMax sound card.
I have Input set as 'DigitechRP155' in
Output set to 'SoundMax 1/3 out' also tried '2/4 out'
Driver mode is set to 'WDM/KS' also tried MME, and 'Asio'
When I select 'Asio' as driver, Soundmax disappears as an output, and although the recording meter shows activity, I have no sound. this is so frustrating! I think I've tried everything, but maybe there's something I'm missing?
