I want to use SQ6 mixer to make multitrack recordings but I don`t have enough knowledge how to set up all connections with the mixer. I have downloaded and installed the driver and connected the laptop to the mixer using usbA-usbB cable. I would appreciate any help concerning this item.
If those are ASIO™ drivers, standard Audacity does not communicate with them 
Possibly try Audacity’s competitor OCENaudio: it is compatible with ASIO, (but Audacity is a more powerful audio editor).
