Wow! @Lemajik really amazing video. I have a few old videos peeps can check out posted in my profile, also using crossfader transitions technique.
I basically use the OP-1 and punch in different parts by moving the fader from the recording loop to the live input. You have some whole extra stuff going on here though! One problem I have is with glitch FX modulating the retrig params stop the recording sometimes which sounds bunk in a performance. How are you having such smooth glitches, is this because all sounds are already in the Octa and not live sampling so its smoother? Also, some of the scene changes that were actually playing new sounds or changing loops etc, what was going on there? Pretty inspiring stuff here, as this is my main use of the Octa,(“Beat Juggling”).
