Question: I went back to 2010 questions and someone asked you "Why marriage rather than co-habitation?" and you answered "What, you mean vs living in SIN?" I thought that was brilliant, but why did you use the word SIN? Were you somewhat religious at that time? Asked by brilliant (154.161.241.x) on November 21 2025, 10:26am Question: Hi, look at this JSFX playback counter. Is it possible for me to keep it on the master track, but then from there it will detect when any track is being frozen and count it too as a playback? So it will essentially track freezing or render as a count. Or this is ridiculously impossible? lol pastebin.com/ztiX0psM Asked by Counter 2 (154.161.241.x) on November 21 2025, 3:48am Question: Did god ever had fun? Asked by Aapo (85.76.81.x) on November 20 2025, 9:59pm Reply on November 21 2025, 2:22am: no idea, but dogs sure do Comment... Question: What do you think of this?.github.com/opensound-org/opensound Asked by yarre (221.215.214.x) on November 20 2025, 1:52pm Reply on November 20 2025, 6:47pm (edited at November 20 2025, 6:48pm): very hard to get a feel for it from the github page... and when I try to browse deeper now github is fucked lol sigh Comment... Question: I wrote my senior thesis in Technological Entrepreneurship. on you I too have a modded x-box 36t0 (don't tell Microsoft lol) and I used Winamp to this day. My first room mates in College didn't believe all the visuals each song produced was based of algorithms that made them do that. Amway's my question is, I just got laid off my job with about 700 people, I was a digital marketing specialist with over 900+ clients. I'd like to know how many ideas youve had in your career and any advice to a young wannaabe Asked by Big Mike (77.111.246.x) on November 20 2025, 11:36am Reply on November 20 2025, 1:26pm: I've had plenty of ideas that I've tried to get others to do rather than have to do myself, or made proof of concepts of but haven't given full long-term effort (reasons: too much work, too hard to get critical mass, not wide enough of perceived audience to justify the work, etc). as far as advice -- find something you enjoy working on and that makes your life better to use. do that and you win, probably other people will have use for it too, but if not at least you'll get something out of it twofold.

Asked by adam (221.215.214.x) on November 19 2025, 6:03pm Reply on November 19 2025, 6:40pm: you could use it to build an audio engine for a game but it doesn't have one ready to go or anything Comment... Question: Hi, Justin. This isn't a question, actually, but a way to inform you that you've inspired me to write this: arnel.bearblog.dev/reaper-slap/Thank you for that.

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. 1 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...
