Hey,
I have uploaded my song using the card manager? How do I get the drum and bass to mix in with the rest of the song. I know you've probably seen this posted before sorry.
plug a patch cord from the headphone out to the line in of your sound card and mix the song on the PS-02 while recording on the computer using Sound Forge or Cool Edit or whatever.
Or, just record the bass and rhythm and then mix it with the other tracks in multitrack software like Ntracks.
