I have an HP Pavilion DV6000 with Intel Centrino running Win8. I am using ASIO4ALL v2, a Prosonus 2.2 usb. I've already recorded multiple .wav files on Audacity and I would like to import those files to Samplitude Music Studio to utilize it's many attributes. However, when I cannot seem to import more than one...and it is in it's own window. I would like to stack each one to mix together. Is this possible? or do I have to re-record them seperately into the program? I am not sure which version it is, it was a gift from a friend. Samplitude Music Studio MX
