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 is properly loaded but I cannot use it (an overlay covers the UI)
FAC Envolver outputs MIDI messages and 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).
Hosts handling properly MIDI and AUDIO with routing support:
- AUM by kymatica
- BM3 by Intua
- AudioBus 3 by Audiobus Pty Ltd
- Sequencism by Rodrigo Roman Castro
- ApeMatrix by ApeSoft
So if you get the following window it means that you are not using FAC Envolver in a compliant host.
FAC Envolver is properly loaded but no MIDI outs (no overlay covering the UI)
- Have you touched PLAY in the transport bar of your host?
- Have you muted the envelopes?
- Have you set the MIDI source in your host?
- Have you mapped the MIDI CC to a parameter?
- Have you set both envelop DEPTH to OFF?
- Have you used Fac Envolver in Garage Band?
This is required to output the MIDD CC.
Both envelope buttons (|1/ and |2/) are toggleable (gray muted/yellow activated).
Please verify the documentation of your host. Fac Envolver uses a virtual MIDI cable calls "Fred Anton Corvest". In AUM for example, each channel provides a FAC Envolver virtual MIDI cable, use the right one.
Please verify the documentation of your host. Verify that the MIDI CC# entered in Fac Envolver are properly mapped to the parameters you want to control.
Increase the depth.
No MIDI out routing provided by Apple :(
Do not use FAC Preset Manager in Cubasis v2.3.1🔄 UPDATE - 27 Mar 2018: Issue fixed in Cubasis v2.4. FAC Preset Manager 100% functional!
There is an issue if the current preset is set via the preset manager provided with FAC AuV3s: Cubasis will hang and freeze. This has already been discussed with Steinberg and they will provide a fix soon.
💡 Workaround: We can not hide the preset manager because as AuV3 plugin we do not receive the info that we are in Cubasis 2. So please, Cubasis 2 users, use the preset organiser provided within the host and do not use the one provided with FAC apps.
➡️ 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
