this morning I were racking my brain to find a solution to record my own bass loops, with my Boss RC20XL( [url]http://www.rolandus.com/products/productdetails.aspx?ObjectId=477&ParentId=96[/url] ). And I found the soultion (aha..).
The problem was that I wanted to be able to edit each layer(adding a flanger to this layer, a reverb to another..) . Then I figured out ableton Live's Clips system could solve my problem: One scene by layer..
In the fact, I first syncronise the tempo between Live and my pedal, then I set the starter of the transport bar on "2 bars". Then I record my first loop on the first scene, then, whitout stoping my pedal, I record the first overdub on the second scene, then the second overdub ect.. and all my composition process displays layered in front of me. Obviously I can switch to the layer I want when I want!
Then I create one track by effect I want, then I move each clip to one theses tracks. By doing this I can by exemple, add a flanger to the 3 first scenes, then a reverb to the next 2 clips ect...
But the old same problems remains..
Let's say that I've 10 layer(so 10 clips by the way), if I wanna do another take of the third layer, but still keep the next 7.
The 7 following layers won't include this new take. I will have to record again the next 7 clips, to make them include the new third layer..
Except this, the combination of the Boss RC20XL loopstation & Ableton Live substitute to the huge footboard RC-50! ( [url]http://www.rolandus.com/products/productdetails.aspx?ObjectId=772[/url] take a look at the first vid, I enjoy what this guy does)
To conclude, I simply hope this trick will useful to any musician using any loopstation pedal...
