But let's be real: it's highly dubious software, exploiting the tired and inefficient trope of the noodly "patch connections" approach made famous by modular synth folks. The sound engine sucks, even with the new updates made recently. The new versions are made using the JUCE framework, and yet it has no Linux support. WTF? Good luck doing anything low-latency, on any platform, using any kind of hardware. Seriously, last time I tried to agonize with Max/MSP, that shit would start crackling at 48k and a block size of 192, that's absurdly poor performance for any sort of "modern" audio software.
Max/MSP is something made to take advantage of "computer musicians" and "audio engineers" who know very little about the actual computing platforms they continue to exploit. These people have become decidedly easy to trick, they simply don't approach their own so-called "craft" with the amount of skepticism they must have in order to continue to practice that craft.
