Spat 5 for Max : read this first!

Where to install the spat5 files

Ircam spat5 is a package for Cycling’74 Max/MSP.
The recommended installation procedure consists in copying the spat5 folder (from the downloaded dmg disk image or zip file) to your “Max Package folder”.
Your “Max Package folder” is typically located in your “Documents” folder, more specifically :
~/Documents/Max 8/Packages if you are using Max 8
~/Documents/Max 7/Packages if you are using Max 7

where ~ represents your home folder, so typically :
/Users/[username]/Documents/Max 8/Packages for Max 8 on macOS
C:\Users\[username]\Documents\Max 8\Packages for Max 8 on Windows

In case you use both Max 7 and Max 8, you might want to copy the spat5 folder in each of the Max Package folders.

Additional step for Windows

Ircam Spat5 Windows version requires the “Visual C++ Redistributable Packages for Visual Studio 2019”.

  • You can (freely) download it from Microsoft website: https://www.visualstudio.com/downloads/.
  • Select Microsoft Visual C++ 2019 Redistributable and x64 and follow the instructions for installation.
  • Restart Max after installation.

Troubleshooting for Windows

A frequent issue is to have an “Error 126 loading external”.
This error message appears in the Max Console when creating a spat5 object (or when opening a patcher that contains spat5 externals). In that case, the spat5 external objects appear in red color in the patcher window and they are unusable.
Typically, this issue arise when the spat5 files have not been properly copied into your “Max Packages” folder. spat5 requires a number of DLL libraries; these DLL files must be in the C:\Users\[username]\Documents\Max 8\Packages\spat5\support folder so that Max can load them (and subsequently load the spat5 externals).

Quarantine on macOS 10.15+

If you are using macOS 10.15 Catalina (or higher), it is possible that the downloaded spat5 files have been “quarantined” by the OS.
As the result, the spat5 external objets wouldn’t load in Max.
To avoid this issue, you need to remove the quarantine. To do so, you need to open the Terminal application, and execute the following command :

xattr -d -r com.apple.quarantine [path/to/extern/directory]

Examples :
xattr -d -r com.apple.quarantine "~/Documents/Max 8/Packages/spat5"
xattr -d -r com.apple.quarantine "~/Documents/Max 7/Packages/spat5"

Further information is available here :

Once you have removed the quarantine, you can start Max, and spat5 external objects should work properly.

Hardware compatibility (AVX)

Ircam Spat5 requires “relatively new” (CPU) hardware. More specifically, it requires CPU with AVX 1.0 extensions.
Typically such hardware extension is available on all mac computers released after 2010.
If your hardware is older than that, spat5 objects might not work, typically resulting in a software crash anytime you try to load an object in Max.
In case of a doubt, you can check if your hardware supports AVX 1.0.

On macOS, execute the following command in a Terminal :
sysctl -a | grep hw.optional
A value of “1” indicates that the extension is supported; “0” is not supported.

spat-avx

On Windows, download and install the Intel Processor Diagnostic Tool to run a diagnostic for your hardware. In the “CPU Features” tab, check if your processor has “AVX Support”. If not, you wont be able to run Spat5.

Hardware compatibility (Apple Silicon)

Ircam Spat5 is currently compatible with Intel-based CPU only.
Apple Silicon processors such as the ARM M1 are currently not supported.
