Hi Robin,

that’s actually quite easy:

 ![sp-wired](https://europe1.discourse-cdn.com/flex017/uploads/sonic_pi/original/1X/7cdc60809085f6af6188e4af91745279c9c4cb28.png)

Every `live_loop` will send its signal to a designated output channel. No. 3/4 from `live_loop` `:arp` e. g. go to the Tal Reverb loaded into Carla. Actually I forgot to remove the connections for channel 1/2, because Sonic Pi sends all its output [automatically on channel 1/2](http://in-thread.sonic-pi.net/t/separate-output-channels-for-live-loops-or-buffers/1028/7). That is why during the performance some distortion can be heard: the `live_loop` `:arp` (channel 3/4) and all others could also be heard on the `master channel` 1/2 (without external reverb); that was a mistake which fortunately did not spoil the sound too much.

Does that help?

As to Carla there is [a presentation from Filipe Coelho](https://www.youtube.com/watch?v=IPwO3NEwsMU) from last year’s Sonoj available (who attended also this year), which gives an exhaustive overview of this fine software.
