I tried one of the Apple ones, it was simultaneously amazing and also a long way from being something I would use. Maybe in a few generations… 1 Comment...

Question: What are you coding tools (OS, text editor/IDE, pipeline, etc.)?
Asked by someone (89.187.187.x) on March 24 2024, 8:00pm
Reply on March 24 2024, 9:40pm:

OS: whichever, usually macOS out of convenience (M1 MBA is light and the battery lasts forever). vim for text editing, and preferred build tool is make (though I'll use a VS version 2013-2022, or Xcode as needed for those platforms). For release REAPER builds we use gcc 4.x for linux, xcode12 for macOS universal, Xcode9+ICC for macOS intel, and VC2005+ICC for Windows. 3 Comments...

Question: Hi, how can I use Winamp on my Mac ? I can't open the app because it constantly crashes, saying that it closed unexpectedly.

Reply on March 18 2024, 8:46pm:

Are you running Windows in Parallels or something? Or is there a mac version you're trying to run? Anyway Winamp isn't something I've touched in about 20 years so I'm probably not the best person to ask. Comment...

Question: Hey justin, don't you think that AI will make all daws obsolete? Can Reaper adapt to this?

Not really, no. Raises all sorts of interesting questions for sure, but I can't say I'm concerned. Did you read the Neal Stephenson novel "Fall" ? 1 Comment...

I don't do a lot of Java but my memory is that Java doesn't have a main() function (as C/C++ do), but a main class instead? Comment...

Question: Hey Justin, what would be your suggestion for the best way to learn how to develop plugins from scratch? YouTube, Books, Websites, School? I think I'm having decision paralysis

Reply on March 14 2024, 4:29am:

It's always hard to know the answer to this kind of question, the only way I've experienced is one that is long and thus probably not what I would recommend! I'd say start with the VST3 SDK examples and go from there... 2 Comments...

Question: Software architecture for multi-threaded GUI: back when you were designing REAPER projects would it make sense performance-wise for a threaded msg_loop where its thread was associated with an instance of main dialog? Leaving ``tab switch'' to the operating system similar to how IE was working back then.

Question: What's your opinion on the trend towards closed ecosystems, especially "hub apps" in music tech like Native Access, Splice, UVI Workstation and all the DRM management stuff?

Big thumbs down, obviously. Computers should be about giving power and flexibility to the users. This is part of why I'm very anti-app-store when it comes to distribution. 7 Comments...

Question: If you compare the past and present, how has the process of making software known worldwide changed? Winamp was known worldwide back then. Did it work by word of mouth? And has that changed with Reaper? Greetings
Asked by Stefan (84.160.46.x) on March 6 2024, 9:15am
Reply on March 6 2024, 6:55pm:

Hard to say, I think good stuff spreads by word of mouth, just takes time. REAPER's userbase has grown a lot more slowly than Winamp's did, probably because it has taken a lot longer to develop, came to a market that was both a lot smaller and already very full of other DAWs. If you make a great app that does something new that a lot of people want to do, I imagine it won't take long to find a lot of users. Comment...
