Yes, Max can probably do more than you will ever need but this is normal. Nobody uses all of the program. Some people build MIDI routers and processors, some build synthesizers, sequencers, audio effects, generative patches, museum installations, sensor applications etc.
However, Max is expensive and it really takes a while to learn the basics. The fun comes afterwards. You could risk 1-2 months subscription if you are not convinced after the 30-day trial period.
I would love to hear the things you have done... do you have any examples to share?
MP4 movie: Generative Text
A demonstration of a generative music system I tried in Max. The idea was, that rhythmic melodic text should produce rhythmic melodic music. The first half plays capital letters and pauses. The second half plays upper- and lowercase letters as notes and makes pauses after syllables, words, sentences and paragraphs. The sound comes from two AU plugins, one for uppercase and one for lowercase characters. Notes and weighting per character are in a kind of table, based on the German language (simple statistics).
I think the example covers some of the bandwidth Max is capable of. Sometimes you need a bit of a programmers brain, sometimes technical creativity. And you must not get scared of endless possibilities.
The "Help" files and the "References" for each single object right in the program are invaluable sources for learning and refinig the skills. YouTube provides Max tutorials. The Max forum is pretty good but not really friendly to beginners. You rather want to read and search in the forum before you start with questions.
