Live loops thru different audio outputs?

General

hi everyone :slight_smile: I hope your all well :slight_smile: if I have sonic pi running thru an audio device with multiple outputs and I have a few live loops in a project how can I get each loop to run through a different audio output? your help with this question would be most welcome, kind regards trey.

hi thanks for your help so I have the following code:

“”"
live_loop :kick do
use_bpm 140
if ring(:true, :true, :true, :true).tick
sample “/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/dt02_kick-classic_bitleash.wav”
end
sleep 1
end

live_loop :snare do
use_bpm 140
sync :kick
if ring(:false, :true, :false, :true).look
sample “/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/909 Snare.wav”
end
sleep 1
end

live_loop :hh do
use_bpm 140
sync :kick
if ring(:true, :true, :true, :false).tick
sample “/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/dt02_hi-hat_acutran-b.wav”
end
sleep 1
end

how would I get those live loops to different outputs of my sound card? I red the tutorial but if some one could make a real world sample from these that would be great thanks :slight_smile:

Hi @soundwarrior, did you fix this?

If you go bottom of log @ %userprofile%\.sonic-pi\log\scsynth.log you can see the devices and the outputs, which may help with :sound_out config.

Let’s keep it simple and assume your default device is the sound card you want to target, and has multiple outputs, and we’re targeting each individually, in mono.

by default, the :sound_out FX outputs a mono mix of the stereo input to a specific channel

with_fx :sound_out, output: 1 
  sample :bd_haus     
end

If you simply want some loops to go to one channel and other loops to another, this may work:

NB: As you’re using external samples I moved these, for easier adjusting, to :symbols
To pass a sample’s path (that’s a symbol) to the sample method you need to use set and get (check the docs for examples - :bulb: type set then press “ctrl+i”)

To avoid having to write sample get[:sample_path] every time, I wrapped it up in a sampl method, then edited the code and ran to make sure it worked.

your code rewritten WITHOUT :sound_out

#your_sample_paths
##| set :k,“/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/dt02_kick-classic_bitleash.wav”
##| set :s,“/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/909 Snare.wav”
##| set :h,“/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/dt02_hi-hat_acutran-b.wav”
set :k, :drum_heavy_kick
set :s, :drum_snare_hard
set :h, :hat_snap

define :sampl do |sam|
  sample get[sam]
end


live_loop :kick do
  use_bpm 140
  if ring(:true, :true, :true, :true).tick
    sampl :k
  end
  sleep 1
end

live_loop :snare do
  use_bpm 140
  sync :kick
  if ring(:false, :true, :false, :true).look
    sampl :s
  end
  sleep 1
end

live_loop :hh do
  use_bpm 140
  sync :kick
  if ring(:true, :true, :true, :false).tick
    sampl :h
  end
  sleep 1
end

Then to add the :sound_out to make loops go to particular outputs you can wrap as required

#your_sample_paths
##| set :k,“/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/dt02_kick-classic_bitleash.wav”
##| set :s,“/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/909 Snare.wav”
##| set :h,“/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/dt02_hi-hat_acutran-b.wav”
set :k, :drum_heavy_kick
set :s, :drum_snare_hard
set :h, :hat_snap

define :sampl do |sam|
  sample get[sam]
end


live_loop :kick do
  use_bpm 140
  if ring(:true, :true, :true, :true).tick
    with_fx :sound_out, output: 1 do
      sampl :k
    end
  end
  sleep 1
end

live_loop :snare do
  use_bpm 140
  sync :kick
  if ring(:false, :true, :false, :true).look
    with_fx :sound_out, output: 2 do
      sampl :s
    end
  end
  sleep 1
end

live_loop :hh do
  use_bpm 140
  sync :kick
  if ring(:true, :true, :true, :false).tick
    with_fx :sound_out output: 2 do
      sampl :h
    end    
  end
  sleep 1
end

You may notice there’s some repetition of code there.
You may also notice that the default output: option is 1 , so that doesn’t need writing explcitly…

One last rewrite, to make the sampl method also control the output, we can do something like this

#add default value to out argument
define :sampl do |sam, out = 1|
  with_fx :sound_out, output: out do
    sample get[sam]
  end  
end

Then whenever you want a sample to go to a different output you can just add that option… Here’s the version that shows this.

#your_sample_paths
##| set :k,“/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/dt02_kick-classic_bitleash.wav”
##| set :s,“/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/909 Snare.wav”
##| set :h,“/Users/soundwarrior/Documents/reaper personal/projects/sound warrior/delay rave 140/delay rave drum samples/dt02_hi-hat_acutran-b.wav”
set :k, :drum_heavy_kick
set :s, :drum_snare_hard
set :h, :hat_snap

define :sampl do |sam, out = 1|
  with_fx :sound_out, output: out do
    sample get[sam]
  end  
end


live_loop :kick do
  use_bpm 140
  if ring(:true, :true, :true, :true).tick    
      sampl :k #no option provided so out=default(1)
  end
  sleep 1
end

live_loop :snare do
  use_bpm 140
  sync :kick
  if ring(:false, :true, :false, :true).look    
      sampl :s, 2  #output to channel 2
  end
  sleep 1
end

live_loop :hh do
  use_bpm 140
  sync :kick
  if ring(:true, :true, :true, :false).tick
    sampl :h #channel 1
  end
  sleep 1
end

Hope this helps someone!
