- Thread-topic: internalRenderBlock sometimes not called for MIDI FX plugins in Logic Pro
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.
Take care,
