Hi, I've released an open-source AUv3 MIDI processor plugin for iOS and macOS that records and plays MIDI messages in a sample accurate fashion and doesn't ever apply any quantization. I've tested this plugin with 120 beta testers and everything seemed to work fine. However, now that I've released it, there seems to be a problem in Logic Pro X on some Mac computers with MIDI FX processor plugins that are using Catalyst. You can find my plugin here: http://uwyn.com/mtr/ ... and the source code here: https://github.com/gbevin/MIDITapeRecorder When I trace the AUv3 instantiation, I see Logic Pro X obtaining the internalRenderBlock several times, but then never ever calling it. This means there's no render callback and there's never any MIDI parameter events received. I've talked to the developer of ZOA, which is also a MIDI processor plugin using Catalyst and he's running into exactly the same problem: https://www.audiosymmetric.com/zoa.html Another developer that’s working on a MIDI processor plugin has been trying to track this down for weeks also. When I test this on my M1 Max MacBook Pro, is always internalRenderBlock, however an my M1 MacBook Air and Intel 2019 MacBook Pro, it is never called. Any thoughts or ideas to work around this would be really helpful. Thanks!

Hi, I'm prototyping a visionOS app for which I'm trying to create the following behavior in mixed immersive space: users pinch and drag to position a model entity in the real world starting from the ray-cast of the pinch, meaning that the initial position should be on a MeshAnchor from scene reconstruction (I got that working, even though it's less precise than I expected) once the model entity is positioned, I want to anchor this to the world so that it will always stays there no matter what, from what I understand I need to create and add a WorldAnchor to a WorldTrackingProvider for that after positioning the model entity, users should be able to pinch and drag the entity to change its position and have that be persisted from then onwards It's not clear to me what the relationship between AnchorEntity(world:) and WorldAnchor is (looks like AnchorEntity(anchor:) isn't available in visionOS). What is the recommended way to keep these together? Afterwards, what is the recommended way to covert coordinate spaces between repositioned scene coordinate space and the anchor entity hierarchy coordinate space? I tried a DragGesture on the model entity and convert the translation to the scene, that works only when the scene origin hasn't changed. After it has changed, the translation is using the wrong coordinate space. Thanks for the help! Geert
