FAC AuV3 Known Issues
FAC Plugins are Audio Unit Extension, or AuV3. It's the evolution of the Audio Units V2, presented by Apple at #WWDC15 and aim to be used on iOS, tvOS, and macOS by host apps and distributed via the App Store.
➡️ Known Issues on iOS
FAC Envolver - No MIDI OUT
In order to output MIDI messages, an AuV3 requires to be run in a compliant system (iOS 11.0+ or macOS 10.13+) and in a host providing a valid MIDI output block (AUMIDIOutputEventBlock).
- Sequencism by Rodrigo Roman Castro
- ApeMatrix by ApeSoft
- AudioBus 3 by Audiobus Pty Ltd
- AUM by kymatica
- BM3 by Intua
Note: Being a MIDI/AUDIO fx makes FAC Envolver usable in every host, even the ones that still do not provide MIDI out support, in this case the MIDI generator is disabled and the fx can be used as a standard AUDIO fx.
If you still have issues in a compliant host, check the following points.
- Have you disabled MIDI out? Both slot buttons (|1/ and |2/) are toggleable (gray muted/yellow activated).
- Have you properly set the MIDI source in your host? Fac Envolver uses a virtual MIDI cable called "Fred Anton Corvest".
- Have you mapped the MIDI CC to a parameter? Verify that the MIDI CC# are properly mapped to the parameters you want to control.
- Have you set both envelope DEPTHs to OFF? Increase the depth.
FAC Envolver - Host Transport Bar Issue when the trance gate circuit is engaged
BM3 (known BUG that Intua will fix soon): FAC Envolver is muted when you hit play at the very beginning of the transport bar.
Sequencism (known BUG that Rodrigo Roman Castro will fix soon): The transport bar information provided to the AuV3 plugins are not accurate and lead to desynchronization.
➡️ Known Issues on macOS
FAC AuV3s not supported in a no compliant AuV3 host
Seems that you have not read the warning before purchasing... See the screenshot below.
💡 Workaround: Write to the company of the host which is not compliant to beg for AuV3 support :)
FAC AuV3s missing in Logic Pro X
It's probably the first time you use it, and the AuV3 is missing in Logic Pro X or available but surrounded by an orange exclamation mark
💡 Workaround: You have to check "AU3 Mode" in Logic Pro X/Plugin Manager
Under some circumstances, I get an orange exclamation mark over FAC AuV3s in Logic Pro X.
It's very strange because the plugins worked perfectly!
This is a weird bug in Logic Pro X, we have already notified Apple. Please do the same to get more chance for a fix.
💡 Workaround: Follow the procedure as described in the following video: LPX AuV3 Exclamation Mark Workaround
