A few years ago I created a technique for live looping in Ableton Live. I wanted to record and stop recording a clip in the session view without using a bulky MIDI foot controller. So, I came up with the idea of modding a mouse by connecting a simple sustain pedal into the left button. This way I could keep playing my instrument with both hands and record to any clip that the mouse cursor was resting on.
I found that I could do lots of other things while continuing to play two handed, like start a scene, stop a clip, mute a track, etc. Usually I reserve setting up my modded mouse for shows, but it’s a very useful tool in the studio for capturing two handed keyboard parts, like the Rhodes in this segment from a new track.
Live Looped Studio Rhodes
While sorting through dusty clips from live performances I came across an angular Rhodes line that sounded quite odd removed from the context of the original set. 
I registered the 
Here’s another example of audio that was recorded for the purpose of live looping during a performance. 
I came across this sample from a performance on July 13, 2006. It is a delayed synthesizer line that I played and captured as a clip in Ableton Live during the show. What’s interesting to me about this clip is the obvious modulation in pitch on the delay trails. This is not something that I programmed into the patch and I suspect is actually caused by a bug in the Korg MS2000. It’s possible to recreate this bug by enabling tempo delay then sending external sync to the instrument. I rarely experience this glitch anymore because rather than using the delay on the Korg, I usually run it through tempo delay in the software. However, I kind of like the ghostly quality it creates in this short passage.
