AW: DJ techniques in live looping (Re: video on loop turntablism) - also for Jeff Larson!

Hey Per and Aaron (and also Jeff Larson btw),

products like the xponent have been available for quite some time, and
there's even really cheap ones to get you started (avoiding the B word
here). On the other end of the (price) spectrum, you have solutions like
Final Scratch, where you basically still have a set of turntables, playing
timecode vinyl to control your software, which, according to DJ/turntablism
people, works outstandingly.

Now Per, you noted a reason for you to not use a turntable interface:

Here I might add: one of the beauties of loop playing is that, from time to
time, you have the possibility to use your instrument-playing hands to e.g.
work a set of wheels of steel while the loops are running on.

Unfortunately, I've yet to find a powerful looping tool (in our sense of 
word, with all the overdub and first loop capability thingies going) that
has a control interface that more relates to DJ work (correction: had to,
until Flyloops implemented that). The typical looper has buttons for
transport control (play/stop, reverse, halfspeed), and some loopers also 
playback speed control (like the Repeater's varispeed or Mobius' Rate
On the other hand, tools more targeted at a DJ-related market (which, on 
other hand, often lack functions like first loop capability or overdub)
sometimes offer also DJ-oriented transport control. One example would be 
Kaoss pad series, where you have those algorithms where you can scratch 
loop sample in various ways. Another example would be the Roland (I think)
D2, which also has a scratch pad.

Now Jeff (and this is why you're mentioned above): would it be possible to
control a loop in Mobius with one of these controllers like a Kaoss pad, to
"sratch" the loop?

Actually, Ableton Live implements a crossfader functionality (if that's 
you're hinting at with "crossover mixer"), where you can assign any track 
one of two busses and then mix between them with a crossfader - which, of
course, can also be controlled by an expression pedal.

I see this as different things - if a direct jump was the same as a
crossfade, then all those (hiphop) DJ mixers would have a switch instead of
a crossfader, wouldn't they?

Again, Ableton Live has a plugin called "EQ3" which is a kind of DJ EQ:
3-band graphic eq, selectable crossover frequencies and filter steepness 
kill switches for all three bands. I used to apply that a lot in my former
(i.e. 2005-2007, as documented on my "Weird Specialist" album) work a lot,
with one of those sitting on each track with loop content (drum machine,
pre-recorded drum loops and Mobius returns).
