bass station doing hoovers?
not heard that b4 but then again i have never used one - i thought it wanted to be a tb303 but failed
anyway , u can connect your pc outs into your mixer left channel , your synth outs into your mixer right channel - your mixer main outs to your speakers and your mixer CR/aux outs(if it has them) to your soundcard ins
(so you can record and track it one track at a time)
have fun
