Question: Shouldn't the neglect of reaplugs come to an end and a linux version finally be created?

meh nah, plug-ins and frameworks etc on linux are a nightmare. swell uses GDK, which would be a mess to use as a plug-in, is my understanding. also reaplugs as a product is a timesink that takes resources away from other projects. Comment...

Question: Hi, please is it possible to implement lookahead in a jsfx limiter I'm working on, where the lookahead is actually reported and automatically compensated. I haven't yet seen any lookahead jsfx limiter which reports the latency?

Reply on January 22 2025, 3:58am:

Definitely, you'll have to manage the delay yourself, but you can report pdc to the host using pdc_delay/pdc_bot_ch/pdc_top_ch etc (see the docs). Comment...

Question: Best place to send a slew of Reaper MIDI Editor bugs/mishaps as to not spam the bug report forum and to make the time in putting the report together worthwhile?

Put 'em in a single thread on the bug report forum, but also if you're not using the pre-release version try that one as it's been getting some attention. Comment...

Question: Does Reaper by any chance use SIMD instructions (Such as MMX, SSE4.2, AVX, AVX2, NEON, and SVE) for DSP/Audio? Because I been in a rabbit hole for the past couple of weeks regarding DSP and SIMD, and it has been very fascinating to say the least. And I plan on applying those concepts I have learned towards a project of mine and was wondering if you also did the same thing whilst working on Reaper.

We mostly let the compiler do it, sometimes unrolling performance-sensitive loops slightly in order to make that possible, and occasionally will use intrinsics or assembly though that is relatively rare and usually best avoided because you really don't want to have to maintain 3+ different versions of things.

Question: If anything, what do you regret most not having done differently in REAPER at some point because now it's hard to change/hinders development etc.?
Asked by wasereb4 (95.91.77.x) on January 12 2025, 1:11am
Reply on January 12 2025, 6:10pm:

hah too many things to pick one... the one I'm most dreading fixing at this moment is the notion that the realtime monitoring/FX/etc don't run while prebuffering the project for playback. That is something that should be simple to fix but there are a thousand places with assumptions that will be incorrect that will probably need to be fixed. there are dozens and dozens of things like that, I suppose Comment...

Question: Since you no longer "hoard" music, how are you consuming music these days? Spotify? Apple Music?
Asked by Will (23.125.224.x) on January 10 2025, 4:04pm
Reply on January 10 2025, 5:11pm:

I listen to and buy albums preferably via bandcamp. I have used Spotify to work through the catalog of a few bands, most recently The Cure, which has been fun, but I feel like with the amount I listen to the majority of the month's Spotify subscription didn't go where I would've wanted it to. I really wish there was a music service where if I pay them $X/mo, 80% goes to the artists who I listened to that month. That would be awesome. 1 Comment...
