Tutorial : How to record FoxDot multi outputs in a DAW.
When we started recording our album REISUB, we thought it might be a good idea to be able to record each FoxDot player on a separate track.
This tutorial will show you how to do this with our hardware and software configuration, hoping that it can be useful to you. It should work on other configurations and other OS but here is the one we use:
- Linux Ubuntu Studio 20.04
- Python 3.8
- SuperCollider 3.11
- Carla 2.1 (for JACK routing)
- Ardour 6.3
- Behringer UMC404HD soundcard (but it should work with any soundcard)
In the following examples, we will record 3 stereo tracks (drums, bass, synth) and the master track which is FoxDot’s default output track.
>> Configure SuperCollider for the multichannels
By default, FoxDot outputs are set to 2, that mean you can only record one stereo bus (Ouput 0, Output 1). In order to record 4 stereo tracks we need to change the max output of the FoxDot Quark to 8.
In SuperCollider go to :
- Language / Quarks
- Select the FoxDot Quarks and click Show classes
- Select FoxDot and Open File
- Close all windows and look at the FoxDot.sc open in the SuperCollider window (image 1).
Or you can simply open in SuperCollider :
server.options.numOutputBusChannels = 2 and change it to
Reboot Supercollider and now you should see SuperCollider with multi outputs in JACK or Carla (image 2).
>> add an output fx in foxdot
To be able to assign an output to a player, we will add an fx in foxdot. If you don’t know how or if you are lost you can read our previous tutorial on FoxDot customization.
The easiest way is to edit
/FoxDot/lib/Effects/Util.py and add this code before the last 2 lines.
fx.doc(“Output select Bus”)
This output Fx should ALWAYS be the last FX you add in this file.
Save and restart FoxDot and if it works, at the startup FoxDot create this file
>> route the SuperCollider output to a DAW
Open your favorite DAW, in our case Ardour, and add 4 stereo tracks (image 3) named :
- “FoxDot Master”
In Carla (or with JACK), connect the SuperCollider outputs to the correct Ardour inputs (image 4).
- Output 0/1 -> FoxDot Master
- Output 2/3 -> Drums
- Output 4/5 -> Bass
- Output 6/7 -> Synth
>> play & record the 4 stereo tracks
In FoxDot write the best code you can and don’t forget to add the output fx in each player you want to record :
b1 >> dbass(dur=1/2, output=4)
s1 >> pluck(dur=1.5, output=6)
Remember, output(0,1) is by default for the FoxDot output so you need to start with output(2).
As these are stereo tracks, the next available output is output(4).
In Ardour, arm all tracks and press the record button. If it works you should have the 4 tracks recorded separately (image 5).
