Question: I am really sorry, but I am discussing here to make my favorite DAW follow an external MIDI clock. forum.cockos.com/showthread.php?p=...I want to cut the recorded content to fit the grid in order to reuse the improvised content of Renoise and REAPER as a pattern. 0x0.st/XBmc.mp4You once said that `REAPER needs predictability.` I am not sure what you mean by that. What does that mean? askjf.com/index.php?search=midi%20clock

    REAPER needs to be able to predict tempo changes in the future in order to transform media, pre-render FX, etc. If you want to sync in realtime to tempo changes, a lot of things will break.

Question: What are your pros and cons of cargo bikes vs bike trailers?
Asked by PedalingPanda (194.156.7.x) on July 6 2024, 7:04am
Reply on July 6 2024, 3:54pm:
    Bike trailers you don't have to use all of the time, and when you're not using it you can treat it like a normal bike (easier to deal with, take indoors, etc). But for moving a lot of stuff I'd prefer a cargo bike, much less tedious to ride.

Question: Can you tell in easy language what is ReaScript and if I learn python fully, what I can do? Create my own effects or even instruments for REAPER?
Asked by Abhi (207.244.71.x) on July 6 2024, 6:10am
Reply on July 6 2024, 3:53pm:
    For effects or instruments in REAPER, the easiest thing to learn would be JSFX, which is the EEL2 language (or C++ for making CLAP plug-ins or whatnot, but that's less easy).

    ReaScript is better for higher level stuff, programming the REAPER UI, etc. While you can use Python for it, using Lua or EEL2 offers better integration.

Question: You said you use Mac and not Windows. Then why REAPER's manual has Windows' version in almost all pictures?

Question: I'm not a Pearl Jam diehard by any means, but I really recommend the new album Dark Matter since you liked Ten so much back in the day. It's the same vibe. Very, very good!

    thanks, I'll check it out! Edit (Jul 8): gave it a full listen, pretty good! At its high points I liked it a lot, though I did find myself a little bored at times. That second half of the last track was really good, but there's another song I've heard in the last 5 years that I am very highly reminded of, gotta figure out what that was. Gonna wrack my brain on that one while I go for a run in the 90+ degree weather now. Edit again: ah, one of the Verve songs off of Forth, I think. Very different song but some common progression and feel in there

Question: Hello Justin. By chance, the release days of the pre-releases always coincide with the birthday of some member of the Forum, intentionally?

    Hah unintentionally, sure, the forum has enough members to cover every birthday no doubt.

Question: Snapdragon Windows Arm version of Reaper, when?
Asked by Michael (129.222.78.x) on June 30 2024, 1:17pm
Reply on June 30 2024, 1:46pm:
    Our pre-release site has an ARM64EC/Windows11 build of REAPER 7.04rc1, but there is pretty much zero demand for it as a platform, last I checked. Perhaps we'll update that build in the next few months.

Question: Do you think complicated software like REAPER can be developed just using HTML, CSS & Javascript?
Asked by Abhi (110.227.151.x) on June 30 2024, 8:26am
Reply on June 30 2024, 1:45pm:
    The UI could for sure, but you're very limited when it comes to threads (you can have workers but no shared memory) and plug-ins (n/a).

Question: CreateProcess exists in UTF-8 hooks but not in SWELL emulation. Do I have to manually control the situation with posix_spawn or fork()/exec()? Thanks.
Asked by Gio (94.70.6.x) on June 30 2024, 5:15am
Reply on June 30 2024, 1:44pm:
    Rather than implement and try to emulate the full CreateProcess API, we instead offer SWELL_CreateProcess() (and SWELL_CreateProcessIO() on macOS).

Question: Out of complete curiosity. What is "./REAPER/Plugins/reaper_host_x86_64" and what is it used for?
Asked by Matthew (76.37.54.x) on June 29 2024, 5:13pm
Reply on June 30 2024, 1:43pm:
    It's used for when a plug-in is hosted out of process, which can happen due to be set to "separate process", or if it's x86_64 and you're running in arm64 etc.

Question: is it possible to know what audio file the peakfiles in reaper/reapeaks point to? filenames are some big hexadecimal for me and it doesnt look like there's a reference string in the .reapeak content

Question: Are there any binary search trees in the REAPER code?

    Not off the top of my head. Lots of sorted buffers that are bsearch'd though.

    You could obfuscate it if you want, I suppose. There are tools to do that.

Question: Hey Justin! You've been around for a minute - what (if anything) do you miss about the 90s era of computing / internet culture?

Reply on June 22 2024, 9:52pm:
    Hah not too much, things are pretty sweet now. I'd say I miss upgrading your Windows install being optional, but I don't really use Windows anymore unless I have to so it doesn't bother me much...

Question: Hey jf - The plugins that are bundled with Reaper. Were they developed on top of a custom plugin architecture or just regular VST? And if so, how would you go about implementing one?
Asked by Matthew (76.37.54.x) on June 21 2024, 8:22am
Reply on June 21 2024, 3:23pm:
    They are VST-ish, but if you were to implement something similar you'd have to use VST2, which isn't freely available unfortunately. Closest thing to it is probably CLAP, which would be a better alternative!

Question: Are you the best DAW engineer alive?
Asked by Will (23.125.224.x) on June 21 2024, 3:43am
Reply on June 21 2024, 3:22pm (edited at June 21 2024, 4:16pm):
    Not sure how one would quantify best. Lots of potential criteria to choose from, and even then the context would be different, you can't directly compare marathon times on vastly different courses. But any rate, I'm going to go with "no" as an answer.
