Question: Are you also waiting for Half Life 3? Asked by Jose Sacudidor (80.187.85.x) on November 18 2025, 4:09pm Reply on November 18 2025, 10:31pm: Nah not really a gamer at this point Comment... Question: Hi, is there any way I can know whenever you update the JSFX manual. I have made a pdf version of it for myself and wanted to follow and update it whenever you update it or I have to go through the whole thing online to see if you added stuffs? Asked by Manual (154.161.145.x) on November 18 2025, 12:41pm Reply on November 18 2025, 1:19pm: not really. we did recently add the documentation for ext_gr_meter, and before that the config: option -preserve-config. Ideally we'll put those in the REAPER changelog... Comment... Question: do you know of Ninjam users , who play over mobile network in cars , trains , ships ? remote music in moving objects ... Asked by Bernd Keul (87.78.234.x) on November 18 2025, 1:08am Reply on November 18 2025, 1:19pm: hah wouldn't surprise me but don't really know. Comment... Question: A compressor with lookahead that reports its pdc, someone said I should put this in code pdc_midi = 0; to prevent midi from being delayed but I thought this is just a compressor that acts on audio, doesn't JSFX by default prevent MIDI delay, especially since this is not a midi effect. I'm a little bit confused about this whole thing. Is he right? Asked by pdc_midi (154.161.187.x) on November 17 2025, 6:40pm Reply on November 18 2025, 1:22pm: If you set pdc_midi=1, then MIDI will not be delayed. If you're passing MIDI through, leave pdc_midi=0. If you're using the MIDI to control the compressor, or the compressor to modify the MIDI, then you'd want to set pdc_midi=1, and manually delay any passed-through MIDI. 3 Comments... Question: So on the forums, if our upload limit is reached the only choice we have is to go back to our previous posts to delete our pics and media? Pls the storage allocation is too small especially after posting gifs for bug reports. Asked by Question (197.251.240.x) on November 17 2025, 5:01pm Reply on November 18 2025, 1:25pm: Yeah.. I've increased the limit to 5MB from 1.5MB, but you can still run up against it. 1 Comment... Question: Hello. You've done a lot of audio work in your life (Winamp, Reaper). Were you never interested in video? If you'd had a Super 8 camera as a child, would Reaper be a video editing programme today? Asked by gideonstar (217.228.234.x) on November 17 2025, 10:01am Reply on November 17 2025, 11:16am: reaper does a pretty good programmer's video editor, I've made a lot of stuff with it too. Comment... Question: I prefer to look at the changelog from this site (landoleet.org/whatsnew.txt instead of the forum or the script that generates the color-coded changelog. How can I use the numbers like t=304696 on that website to get to the thread, is it a number I could post in forum search to get to the thread? Asked by Changelog (197.251.240.x) on November 16 2025, 2:15am Reply on November 16 2025, 2:29pm: prefix forum.cockos.com/showthread.php? to it ... so https://forum.cockos.com/showthread.php?t=xyz or ?p=xyz 3 Comments... Question: Reckon you're able to add support to ReaPlay for new MacOS? Asked by dom64 (82.132.237.x) on November 15 2025, 8:06pm Reply on November 15 2025, 8:37pm: it works already no? 2 Comments... Question: Do you master assembly language?Is it used in the reaper? Asked by deel (221.215.214.x) on November 15 2025, 12:48pm Reply on November 15 2025, 2:23pm: not sure about what it would mean to master, but when you program enough, languages and assembly in different architectures become a little bit irrelevant, you get used to virtualizing the machine (be it virtual in the case of C, or literal in the case of assembly) in your head. REAPER is mostly C++ for portability, but there are parts that are in assembly, particularly JSFX which generates machine code on the fly to execute for each architecture. So there you're not so much programming in assembly, but programming something which generates assembly. For example, the arm64 stubs for macOS, and the glue code for that. Comment... Question: Have you seen this youtu.be/iu5rnQkfO6M?si=oWFLyQxkmVaMXNFE Asked by Ruchira (175.157.11.x) on November 14 2025, 8:50am Reply on November 14 2025, 3:52pm: lol I hadn't, nice Comment... Question: How do you feel about this one? youtube.com/watch?v=pB7Cmayu56g Asked by Will (99.100.219.x) on November 13 2025, 4:06pm Reply on November 13 2025, 7:53pm: it is a good song for sure Comment... Question: Could you point me to any resources for implementing license file copy protection for apps (specifically Mac apps) like you use in Reaper? Asked by reaper_fan (79.127.217.x) on November 13 2025, 3:30am Reply on November 13 2025, 7:54pm (edited at November 13 2025, 7:55pm): hmm if I were you I'd use something like https://github.com/libecc/libecc, and then have a signed thing which means "I'm licensed." but just to be clear, reaper doesn't have copy protection per se, just a legitimately-licensed indicator. 2 Comments... Question: Have you read any of Stanisław Lems works? If so, how did you like them? Asked by SpoiledHobo (77.187.134.x) on November 12 2025, 8:49pm Reply on November 12 2025, 9:49pm (edited at November 13 2025, 7:54pm): Pretty good! Though I read them in English so who knows how they translated... I remember the one about the machine that can only make things that begin with a particular letter. which was funny, but also I wonder how many liberties the translator had to take to make that work... Comment... Question: In a normal compressors like ReaComp, does the "Main" input level detector compare the left and right levels and use the one which is higher in level as the detected level or it sums the left and right and use the sum level as the detected level? Asked by Compressor (154.161.130.x) on November 10 2025, 3:14pm Reply on November 10 2025, 3:23pm: In stereo mode, it uses the maximum value of the left and right channels 1 Comment... Question: Can you tell me how to use reaplay? I had to use the keyboard to fully operate him, and I couldn't find how to use it in the documentation. Asked by dear (221.215.214.x) on November 10 2025, 9:37am Reply on November 10 2025, 3:23pm: the reaper plug-in? should be able to click it and stuff? Comment... Question: If you were asked to rank the following programming languages from the one you like to use the most to the one you like the least, how would you rank them? c c++ c# java php lua javascript python VisualBasic go rust Asked by colors (221.215.214.x) on November 9 2025, 1:27pm Reply on November 9 2025, 5:56pm: I haven't really used C#, haven't used Java since the 90s (and eve then minimally), nor have I meaningfully used go or rust or VB. For the remaining languages (C C++ php lua and javascript) I'd say it really depends on what I'm working on. For writing applications then I'd prefer C++, if doing text processing then probably php (amusingly, here's a header file which re-generates itself via php), javascript is great for web page stuff and I've enjoyed writing things there. Lua is fine and nice in that its easily embedded and has very low runtime requirements. Python rubs me the wrong way both syntactically and in that it's hard to embed, and there are different versions and in general it feels like a mess to my soul which is weary of supply chain dependencies... complex question, complex answer? Comment... Question: I'm trying to use this "ext_gr_meter" to report gain reduction in a JSFX plugin but it's usage is not featured in the online JSFX manual. How do I use it to report gain reduction to host? Asked by extgrmeter (102.176.65.x) on November 8 2025, 5:50pm Reply on November 8 2025, 8:34pm: ah will update the online docs, the IDE would give you this helptext: "set to 0 in @init, then update with negative values in @block with current gain reduction. set to 10000.0 to disable GR metering." 1 Comment... Question: there's a friend of mine who can't shout his mouth up talking about boards of canada when he gets drunk Asked by mikhail (2.147.52.x) on November 8 2025, 8:08am Reply on November 8 2025, 3:00pm: I've started a deep dive on them, not bad for the electronic-y music, I hear their influence and their influences both in other things I've listened to at length. Comment... Question: Will Reaper's VST plugin scan detect all VST3 plugins in subdirectories? No matter how many folders there are, I've noticed a strange issue: one folder within my designated VST path can't be scanned by Reaper, and I have to specify the path in full, right down to the folder itself. Why is this the case? For example, if I set the path to D:VST, Reaper can't scan the VST3 plugins inside the "SWAM" folder (located at D:VSTSWAM). I have to use the full path like D:VSTSWAM. Asked by nico (221.215.214.x) on November 7 2025, 7:29am Reply on November 7 2025, 5:42pm: hmm the filtering of the directory separators might be screwing this up in the post. But at any rate, post in the forums rather than here! Comment... Question: What's your learning style? Read up/Research heavily before starting or dive in and look for answers when hitting a wall? Asked by Dylan (175.37.18.x) on November 6 2025, 10:06pm Reply on November 7 2025, 3:08am: some of both I think, depending on how I'm feeling or how much I know I don't know 2 Comments...
