I can see where they're coming from, two major OS's, countless DAW hosts, RTAS, AU, and VST...oh, actually Win and Mac VST..good luck with any .dll converters for using Windows only VSTs in OSX..rolling dice. More choice often equals more complications. All of those factors (plus piracy), must be a nightmare for such a small company. Pluggo was, what, $200 for more than 100 plugs, most of which were infinitely useful & easy to use? Great deal, really. This sort of thing happens, and most companies don't even say they'll return your calls, it's just tough tit-tay. Won't name any names, but was a certain software company whose suite of far fewer plugs with mostly cludgy interfaces cost me way more and they left me in the cold with no upgrade path and no support. Their Not-So-Intact VST was abandonware mere months after I paid $100 for it, too. It was also awesome seeing AbysmalSynth repackaged as a "bigger" synth with the UI that Abysmal should have had from the start. Shame, some of their products sound very nice. A software company that actually responds to people and offers software with great UI's, great sound, with a great price deserves some patience. This is more like Legacyware than Abandonware, it's obvious they're still fielding questions from people who bought their products.
The comment about Ableton only being for stupid house musicians made me laugh...that's kinda like those who say Image Line's FLS is only for techno weenies and beginners. I may not like FLS's workflow, but it's a full music production suite that will do anything the end user takes the time to learn how to do. People use Ableton for all types of music. Among all DAWs, Ableton is the one that offers the most modularity and routing with the least amount of fuss.
The partnership with Ableton seemed like a wise move to me. It would be really cool to see a Live Lite For Max version of Ableton Live for those who just want to use Max by rewiring Live to their main DAW, but I don't know if the guys at Ableton like Cycling74 THAT much. Ableton is solid on both Windows and OSX, so Ableton can deal with that area while Cycling74 can concentrate on porting all the Pluggo plugs everyone loved to Max For Live and providing support.
