As you make the transition to Max 5 from an older version, you
may wish to run old and new versions side-by-side or at least
keep them both installed at the same time. Here are some hints
to make this easier.
By default, when you install Max 5, everything except your
preferences will go into a single self-contained folder. Nothing
from your previous Max version will interfere with the installation
of any previous version of Max.
For best results, you'll want to keep two separate copies of
every file specific to each version. The main reason to do this
is that Max 4 cannot read patcher files created by Max 5, so if
these files begin to appear in the search path, Max 4 may not
behave properly. Not only will it be unable to interpret the
files as patchers, it does not know how to read Unicode text files,
so it can't necessarily read them as text files either. If you
write data files containing extended characters with objects such
, they may be unreadable in older versions. This
issue extends to things like scripts for the js
If you use extended characters in these scripts, you cannot easily
maintain a single version that works in both Max 4 and 5. The moment
you save the file in Max 5, it will be unreadable in Max 4. The
Max 5 can convert legacy Macroman text files to UTF-8, but it will
not save in this format.
Mac users might be tempted to use the technique of creating an alias
to their Max 4 world and dropping into their Max 5 search path. As
folder aliases do not work in the search path in Max 5 as they did
in Max 4. Furthermore, the same version compatibility and search
path problems will crop up if you do this.
Instead of trying to manage one set of files, make a copy of all
your files and move that into your Max 5 search path.
Max 5 does not share preferences with older versions. Preferences files from older
versions are not compatible with Max 5. Do not attempt to copy
them. Use the Max 5 environment to create new preferences.
Max 5 does a better job of interpreting and importing Max 4 patch
data than Max 4 does. So, if you want to create something in Max 4,
copy it to the clipboard, switch to Max 5, and paste it into a
patcher, you should have no problems, assuming that all references
in the patcher data can be resolved. You can also copy Max 4 text
format patcher data from an e-mail client and paste it into Max 5,
using either the Paste command in the Edit menu or the
New from Clipboard command in the File menu.
Max 4 has a slightly
higher CPU utilization doing nothing than Max 5 does. So if you
are trying to gain a bit more CPU while using Max 5, you may
wish to quit Max 4 temporarily.
One confusing issue that arises when trying to run Max 5 at the same time as an
older version of Max is that the virtual MIDI ports created by the Mac version
called "to Max/MSP 1" and "from Max/MSP 1" appear to be doubled. Due to the fact
that old patches may store references to these virtual ports by name, it was not
possible to give them new names in Max 5 to distinguish them from the ports in
Max 4. Furthermore, you will be confused because one of the ports with the same
name will do the opposite of what you expect (it will be output when you expect
it to be an input). To help eliminate the confusion, the virtual ports of other
applications are shown in italics in the Max 5 MIDI Setup window.
