Press play. Fist pump.
else....
I set up with the Commodore Amiga outputting 1/4 and 2/3 as 2 separate pairs into a DJM800 - that way I have (usually) the drums and bass and melodic or additional elements on kill switches / levels / filters / able to route to efx. I set my Amgia MODs up so that they have loop commands and I can break the loop when I feel like it... although often I'm constantly breaking the loops to get through the track more quickly!! (it works for minimal techno though.)
For LSDJ live mode in blocks, part mute / solo, changing synth settings on the fly... with synth settings, I usually copy the synth first then on the build ups switch to that copy so if I'm doing something crazy then it'll snap back to a copy with the right settings when it kicks back in. Seriously, there is a ton you can do and I've come to learn the less filtering, etc, the better on the DMG. Remember it's also about engaging the crowd a big and having fun :-)
