Converting Older Max Documents
While both the old and new documents specify a patcher in terms of objects and connections, the details of how this is accomplished in each format are very different. In addition, far more data at higher resolutions is saved in a Max document, so Max does not provide a way to "export" patches you create to the older format. Max can, however, import patches, either text or binary, from older versions of Max. Below we describe some of the problems you may encounter when importing older documents.
Missing or Incompatible Objects
If you have an old Max 4 folder and you just try to open one of your patches in Max, you may encounter a lot of missing files or objects, because you haven't set up your search path so that Max can see the files needed by the patch. For more information on moving older (Max 4 or previous versions) search path to Max, read Using Old and New Versions of Max on the Same Machine.
In the event that an older third-party object will not work in Max, you will see errors in the Max Console saying the objects have failed to load, but in rare cases, incompatible objects may crash Max.
Documents created with version 4 of Max (and earlier) use legacy Mac-specific text encodings (even on Windows) that needs to be converted to Unicode. In some cases when using non-Roman characters, conversion may not happen perfectly because the actual encoding in the document being imported cannot be identified.
Object Sizes and Fonts
Max uses anti-aliased fonts that may be difficult to read when displayed at small sizes. You cannot switch off the anti-aliasing, but you have several options for making text larger:
- You can select all the objects you want to make larger, then open the Fonts Window by choosing Show Fonts from the Object menu. Use the font panel's size control to increase the point size of the text objects. You can also change the size of the selected objects by opening the Format palette and changing the font size.
- You can zoom into the patch temporarily. Choose Zoom In from the View menu, or use the other functions availble to zoom into your patcher.
Behavior of Specific Objects
Some Max objects no longer support certain messages or features. For a complete list, review Object-Specific Changes.
