I would like to do some performing on Streetjelly and need advice on how to set up my gear with the minimum of changes.

I currently have an Allen Heath 10FX USB mixer with line inputs from my keyboard, mic, a roland sound module and the laptop speaker out. Output goes to two powered speakers. Can I just connect a USB from the mixer back to the laptop and what's the best way to monitor my sound. I don't want to use a soft synth.

Thanks
Tony
