Reaper on M1 keep adding instances of reaper_host_x86_64 which stays hanging in syste

[Tomer Baruch]

Working on a new M1 Pro Macbook pro running macOs Monterey 12.1 with Reaper 6.43

Whenever I open the load effect window an instance of reaper_host_x86_64 start jumping on my task bar and keep jumping there for a while - even if I close that window without loading any plugin and even if I exit reaper. Usually after a few hours of work a few of these jumping reaper_hosts remain hanging on my task bar and eventually I have to force quit them one by one if I want to shut down my computer. This is happening even if I only use native m1 plugins in my project.

Any particular FX cause this?

[Tomer Baruch]

As I mentioned before - this is happening before i load any fx. As soon as i open the fx window this app start jumping on my dock and just stay hanging there even if i don't load any fx

occasionally can't open plugins gui. Happens with many different plugins, most of which are native m1.
Closing the window and reopening doesn't change the situation. Only solution is to quit reaper and relaunch

Hey there, I've been using Reaper for years now and I feel a little ashamed that my first post here is a Bug report. But it is what it is.

I do experience the same things like Tomer does. I try to explain as clear as possible and to narrow down the possibilities causing that.

I put a project of a metal production into apples iCloud to make sure I open the exact same project on different Machines.

Reaper v6.46
Plugins in use:
Neural DSP Darkglass Ultra, Archetype Nolly
Brainworks bx_Solo
Waves SSL EV2
FabFilter Pro-Q3, Timeless 3
Valhalla FreqEcho, SpaceModulator, Shimmer
HOFA IQ-Comp, IQ-Limiter, IQ-Analyser, IQ-DeEsser, IQ-Reverb

All installed plugins a 64bit and the newest version. All Plugins are VST3.

When I load it on my MacBook Air M1 MacOS 12.1 Monterey there appears an icon named: "reaper_host_x86_64" in the bay and stays there. And some of the Plugins are named "Plugin Name (x86_64)" others are normal. You can see it in picture 1, wich is a screenshot of my desktop.
Reaper is loading very slowly and sometimes the "reaper_host_x86_64" crashes and audio from tracks with related Plugins ist not played anymore. Occasionally as mentioned by Tomer the gui is not loading these plugins.

Opened the project on my colleges MacBook Air M1, with exact same specs and exact same plugins and versions installed causes same behavior.

Opening the Project on my iMac i7 MacOs 11.6 BigSur: Reaper loading fast as usual, no "reaper_host_x86_64" and everything does what it should do. As shown in picture 2.

For my understanding: ist that x86_64 the also called "bridge mode" for using 32bit Plugins in 64bit environment? If that is the case, Reaper is falsely detecting 64bit Plugins as 32bit versions, on M1 systems or on MacOS 12.1 Monterey or in combination.

If I open an empty project on the M1 the "reaper_host_x86_64" icon does not show up. When I add plugins that performed normal in the other project ist still does not show up. I loads when I add things like the SSL EV2 or the Neural DSP Archetype Nolly or others.

I hope this might help to trace down the source of that problem because it really affects the usability of reaper when using M1 systems. I never experienced reaper behaving slow unexpected and buggy like this. And I want it to be reliable again, because IMO it ist the fastest and most flexible and also stable DAW out there.

PS: I can not upload the pictures because of a "security Token is missing". If of interest please tell me where to mail those.

Ok so the issue remains and is still annoying me. I've stopped using VST plugins and using only AU versions since with native apple silicon ones they work the same and with intel plugins the apple bridge works much better than the Reaper bridge.

Is there a way to cancel the reaper bridge all together? Right now even though I'm never using the reaper bridge it still pops up every time I try to load a plugin (for the first time in a session) and then it just keeps jumping on my dock. Very annoying behavior! I'd really appreciate a switch to just shut this off and not have the option of using intel VST plugins at all.

@Tomer Baruch
No such issue here, only one instance of the bridging app as it should be, so probably plugin related? If you want to run x86 plugs on the M1 without the bridge app then run reaper in rosetta mode. (get info on reaper.app)

@Captn_Crisis
Your "problem" isn't related to the OP, the "" becuase this is normal. You are running plugins with intel code so reaper has to "bridge" those. Use only M1 native plugins and you'll get rid of that.

[Tomer Baruch]

Well it's been over 6 months and the issue remains. I am using only m1-native plugins but the bridge app is jumping before I even load a plugin. The bridge begins to jump as soon as I open the FX window and click "Add". My usual workflow nowadays because I don't want to wait until this bridge opens is to force quit it as soon as it starts jumping around. It happens only once per session (during the first time I try to load a plugin) and in any case if I don't force quite it, it just stays idle forever - even after I close reaper. So it's a small nag but I wish they fix it already. Every time this jumping bridge appears i'm like mmmmmmmmmmmm come on...

i've upraded to Monterey and it started to show up. Everytime you hit fx button, its just starts, like it scans those plugins and tries to open them before you actually open them. On Big Sur it didnt happened like this.

it happens also when no plugins at all are installed, so its not plugin releted. i've moved them out of folders, cleared cache, reseted. Reaper doesnt detect any plugins... and it stills start this process. Also it happens before any plugins are initialise
