Anyone using this? Any comments would be appreciated (good bad indifferent).
I've investigated it, thought about it, mulled it over, but have had to be honest with myself and admit that I don't have the time to devote to figuring this out. Max/MSP is not just an ordinary audio app or plugin, it's basically an entire programming language.
Now, it doesn't really bother me to play around with learning a programming language, just for fun (I made a brief foray into learning Python not too long ago, and may take a run at Perl at some point), but what I figure with Max/MSP is that delving into it just a little, just for fun, will not make you enough of an expert to create any tools that are any better than the thousands of free audio/midi/DSP applications and plugins that are already out there. And learning Max/MSP well enough to do anything truly worthwhile, is no small undertaking.
So, that's how I talked myself out of buying a copy, though I think Cycling74's "Pluggo" pack is definitely worth getting.
And.... re-reading my post, I guess I should clarify that I know Max/MSP is not exactly a programming language. But it is a sound processing programming environment that's more like a programming language than any other metaphor I can think of.
