I am! I'm definitely interested in crossfading between loops and I do it quite often in my sets. > If your not sure what I mean by crossfading between loops, please > check out this demo: > www.flyloops.com/drum1.swf Yes, I hear you. The guy on the video seems to use a dj mixer and those do all rely on a global crossfade control fader to morph between two channels, typically carrying a turntable signal each. I guess what you are interested in is the MORPHING quality? I mean, a lot of loopers do "cross switching" all the time, jumping from let's say beat three in loop one to beat there in loop two and eventually back again. But there's no simultaneous fading happening here, no morphing, just a direct switching. Don't know if you're interested in loose feedback on the topic, but since this is a discussion list - here we go... A very simple kind of crossfade between two mono loops is to use the pan knob for a stereo channel; if the stereo channel is played back in mono the pan knob will work just as a crossfading volume contol. Myself I have done a lot of crossfading with an analog filterbank that gives the option to use filter cut-off for to morph from one signal chain into another one (picked up the idea long ago from hearing mixes by ARmand van Helden). For anyone using Ableton Live there is a built-in corssfade function: each track/channel can be given an "A" or "B" suffix to bind them for either side of the crossfade controller. When looping with many looping devices or with a multi channel looper I do crossfades by using the volume faders. In Mobius I have certain scripts (binded to physical MIDI buttons on my Faderfox hand controller) that either Fade In or Fade Out the loop playing on a certain Track/Channel. To set off an automized crossfade I simply press two buttons: FAde Out for the playing loop and Fade IN for the silent loop that I want to take over. I tend to prefer long crossfade times for this because I play instruments at the same time, but also because I find that more musically interesting. To create glitchy stuff (that many DJ's do on a dj mixer/turntables) I rather like to use the direct slice cutting of a loop - inserting chunks of new audio here and there. Speaking about Fade In/Out, the AU looping plug-in Augustus Looper already have built-in support for doing that. The GUI have a button named "Fade" and it fades in if the volume is down and fades out if the volume is up - even better than my scripting fix in Mobius! When running multiple Augstus Loop plug-ins this function gives a crossfade functions.
