I have done this before sending audio from Sonic Pi to Ableton via Loopback. The steps that worked for me are:

  1. In Loopback create a new virtual device. Set Sonic Pi as the source. In the Channel Mapping section, select “Manual” and add the number of channels you would like to use.

  2. In your DAW, set your newly created Loopback device as the audio input. Create the individual tracks you need, and assign them to different channels.

  3. Before opening Sonic Pi, in system preferences select your Loopback device as the sound output device.

4.In Sonic Pi, use the sound_out or sound_out_stereo FX block to route your audio out of Sonic Pi. Assign specific channels using the output: opt.

Below is a simple example:

live_loop :one do
  with_fx :sound_out, output: 1 do
    sample :bd_808
    sleep 1
  end
end

live_loop :two do
  with_fx :sound_out, output: 2 do
    sleep 1
    sample :elec_mid_snare
    sleep 1
  end
end
