Hello there! As promised, here is a video of a performance I did with JAY-D. I did not use it to mix songs but to manipulate sound loops. Left side plays a drum loop that I use the effects bitcrush, highpass and lowpass on. The right side plays an evolving chord-pad sound that I use the speed effect on to change the pitch. Additionally a bit of echo and lowpass.
Can I embed YouTube?
