I had an existing audio application written against Juce 1.54.27 on a PC.
Time to convert from old to new (modularized) juce? 6 hours, mostly because I modified the audio classes and had to port the changes. Then, the same day I ported the source code to a brand new iMac/xcode 4.3 system. Time to convert? 2 hours.
So, one day’s hard labor to update my PC version, AND port it to the macintosh. It doesn’t get any better than that. Oh, I have about 5 hours or so total (recent) experience on a mac so far. The fact that JUCE takes care of all the heavy lifting by creating the mac project files probably saved me a week or two of frustration right there. Not to mention how long it would have taken me to come up to speed on ‘standard mac programs’.
Jules, you’re a miracle worker.
