MAXPAT File Extension - What is it and how to open MAXPAT format

Opening MAXPAT files

Have a problem opening a .MAXPAT file? We collect information about file formats and can explain what MAXPAT files are. Additionally we recommend software suitable for opening or converting such files.

What is the .MAXPAT file type?

An abbreviation of Max Patch, the filename extension .maxpat stands for the Max/MSP 5 Patch (.maxpat) file type. This file type has been introduced with version 5 of Max/MSP, famous software by Cycling '74 used for real-time processing of sound, sound effects, video, etc. Max/MSP is built upon Max, which is the name of a special visual programming language focused on interconnecting sound sources with Digital Sound Processor (DSP) modules, controllers, event triggers, etc. into a real-time controllable setup.

Max/MSP uses programs written in Max that are called patches and receive different extensions, depending on the software version. A .maxpat file is a Max/MSP patch intended specifically for version 5 of the software (Max/MSP 5). The new file format is based on the JSON syntax and is backwards incompatible with earlier Max/MSP versions, meaning .maxpat files cannot be opened in Max/MSP 4 or earlier. Apart from Max/MSP 5 and its descendants, .maxpat patches can be used with other real-time sound processing software and converted to/from the previous Max/MSP 4.x (.pat/.mxt) format using open-source converters.
