Program for making music by drawing objects, text, and images on an oscilloscope using audio output.
This allows for 3D rendering of .obj
files, .svg
images, .txt
files, and Blender scenes on Windows, macOS, and Linux.
You can use MIDI to interface with osci-render to make and record music.

Using osci-render is very easy; run the program and choose the file you would like to render, and it will output as audio to visualise on your oscilloscope.
By default, the program loads the example cube object. If this is working, you're good to go and should be able to load your own objects, files, or images!
Control the output using the sliders and text boxes provided. Currently the following can be controlled:
- Translation and speed of translation
- Weight of the lines drawn
- Rotation speed
- Volume/scale of the image
- Frequency
There are some additional controls for .obj
files:
- Focal length of camera
- Rotation speed
- Rotation direction
Additional effects can be applied to the image such as:
- Vector cancelling (every other audio sample is inverted)
- Bit crush
- Horizontal/Vertical distortion
- Image Wobble (plays sin wave at same frequency as output)
- Smoothing
- Image Trace (traces out the image, drawing only a portion of the whole image)
This video explains how to install and use osci-render with Blender. Below is an overview of the process, assuming you've already installed osci-render.
- Download the latest Blender add-on from Releases named
osci-render-blender-addon.zip
- Install and enable the add-on in Blender
- 'osci-render settings' menu will now appear under 'Render Properties'
- Open osci-render
- Click 'Connect to osci-render'
- If the filename in osci-render changes to 'Rendering from external input' you have successfully connected
- Add a camera to the scene (if not already present)
- Add a Scene Line Art object to the scene
- Press Shift+A and navigate to Grease Pencil > Scene Line Art
- Go to 'Modifier Properties' of the newly created Line Art object
- Click 'Bake Line Art' under the the 'Bake' settings to generate line art for the current animation/scene/camera
- You should now see the scene on your oscilloscope!
If there are any problems, please create an issue!
osci-render now has a software oscilloscope built-in! It is a modified version of m1el/woscope, an amazing web-based software oscilloscope.
You can open it from Window > Open Software Oscilloscope which will open james.ball.sh/oscilloscope in your default browser.
If there are any problems, please create an issue!
You can use MIDI to control the frequency of the output - just plug in or open a MIDI software/hardware device and open osci-render and start playing notes!
To control the sliders using a MIDI slider or knob from a physical device, do the following:
- First, plug-in MIDI device
- Open osci-render
- Click MIDI logo next to the slider you want to control
- Red means the slider is 'armed' and waiting for you to choose a MIDI key to associate it with
- Move a CC slider/knob etc. on your MIDI device
- The MIDI logo now turns green, and is controlled by your MIDI device!
Head over to Releases and download the latest .exe
, .pkg
, .deb
, or .jar
.
.exe
, .pkg
, or .deb
is recommended, if possible, as it is simpler to get up and running.
- Download the latest
osci-render-VERSION.exe
from Releases - Open the
.exe
skipping any Windows security warnings - It should open briefly and then close without any user input
- Check your start menu for
osci-render
or openosci-render.exe
atC:\Program Files\osci-render
- Start rendering!
Updating to later versions is as simple as running the latest osci-render-VERSION.exe
again.
To uninstall, use Windows control panel, as you would expect.
- Download the latest
osci-render-VERSION.pkg
from Releases - Since I haven't paid for a developer licence, you'll be warned that it is from an 'unidentified developer' when trying to run the installer
- To mitigate this, do the following (explained on the macOS User Guide)
- Locate the downloaded
.pkg
file in Finder - Control-click the file, and choose Open from the shortcut menu
- Click Open
- Locate the downloaded
- Follow the steps in the installer
- Open
osci-render
from the Launchpad - Start rendering!
- Download the latest
osci-render_VERSION-1_amd64.deb
from Releases - Install as usual, according to your distro
- e.g. on Ubuntu, just double click to open and choose software installer
- After installing, you can execute
/opt/osci-render/bin/osci-render
to run! - Start rendering!
- Download the latest
osci-render-os-VERSION.jar
from Releases- Download the version that is relevant to your OS, otherwise the program will not open
- i.e.
osci-render-win-VERSION.jar
for Windows andosci-render-unix-VERSION.jar
for Linux
- Download and install Java 17 or later
- Run the following command from your terminal to run the
.jar
, substituting the correct path to your.jar
file java "-Dfile.encoding=UTF8" -jar "PATH/TO/osci-render-os-VERSION.jar"
- Start rendering!
I am using Maven for dependency management and to package the program. Doing the following will setup the project. I highly recommend using IntelliJ.
- Download and install Java 17 or later
- Run
git clone [email protected]:jameshball/osci-render.git
- Open the project in IntelliJ
- I use SceneBuilder to edit the GUI
- The FXML project files for each GUI element are located in
src/main/resources/fxml
- The FXML project files for each GUI element are located in
- You're good to go!
You should now be able to run sh.ball.gui.Launcher
and start the program π
