Im having a few issues to be honest as i only have one set of Monitors im using my Apogee Duet 2 as an audio interface but of course when i get up to do a mix it means i have to re wire my speakers every time does anyone any advice or work around for this or is it time to reluctantly sell my Duet is my Traktor S4 good enough for production needs and i also record using an ultra nova synthesizer through the inputs of the duet wil i still be able to do that with my S4 thanks in advanced for your help
