Known Issues on iOS (Some may apply on macOS as well)

• "TIP JAR And Store" Error dialog box message "Something went wrong!"

  The network connection may be restricted by the host, touch the "Retry" button to automatically launch the FAC stand-alone app. If you get the error from the stand-alone app, follow the same instructions provided in the next section

• You can't restore the in-app purchases you already bought

  If the "Restore Purchases" button fails to restore your previous purchases:

  • Check your network connection, WIFI must be active
  • Check that you are properly signed in on your device with your Apple ID
  • Touch the "Buy" button, the Apple Store will let you know that you already own the IAP and will restore it for you

• The AUv3 plugins are missing in your host

  This is very rare, but some of you have already encountered the issue with AUv3s from different branding

  • Close everything, launch the stand-alone app provided with the AUv3 and try again
  • Make sure you are looking into the right AUv3 section of your host (effect or instrument section)
  • Reboot your device (iPhone/iPad)

• Cubasis "Freeze in place" of FAC Drumkit

  If you use the default option in Cubasis to freeze a track containing FAC Drumkit, you may lose some user samples in the beginning of the rendering. This is not the case when you activate the "compatibility mode" (In Cubasis). The default freeze option renders the track by re-allocating the AUv3, without a pre buffering delay required to initialize the AUv3 properly. Note that you can edit your midi clip and add an offset at the beginning. By doing so the AUv3 will be initialized properly.

• Multi selection of files/folders in FAC Drumkit

  The iOS Files dialog (The Document Picker Dialog) does not keep the order of your selection.

• The knobs "duck wet" and "curve" have no effect in FAC Alteza

  The knobs "duck wet" and "curve" are only visible when an additional input bus is provided by the host. Beware that some hosts may provide a muted additional input bus with no support of the sidechain feature, you will see the knobs but the ducking will be ignored. In this case, set the knob "duck wet" in OFF position.

• The AUv3 plugins are muted/bypassed

  Reinitialize the Buffer Size setting of your host to 512 for example and try again

• FAC Envolver works fine as Audio fx but 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).

  Compliant MIDI Out Hosts:

  • 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

  Sequencism (known BUG): The transport bar information provided to the AUv3 plugins are not accurate and lead to desynchronization

Known Issues on macOS

• FAC AUv3 plugins are missing in my host

  AUv3 plugins are fully supported on iOS but rather less on macOS.
  Today, (as far as I know) only Logic Pro X, Ableton, Garage Band, Reaper and Hosting AU, Wotja allow AUv3 plugins loading.

• Logic Pro X: issue with the AU3 mode (Orange Exclamation Mark)

  The loading in process is preferred in LPX, go to Preferences/Plugin Manager and DO NOT check the AU3 mode for FAC AUv3s

• Hosting AU: missing plugin view

  There is a bug in Hosting AU regarding the view management of AUv3s since macOS Catalina (Reported to JUX)

  The view may not be visible: close the plugin and load it again. Occurs only with AUv3 plugins: FAC, Tonebridge Guitar...

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.

NOTE: I try to propose a workaround when it's possible. It's very important that you understand that I cannot solve issues related to bugs on third party technologies, or bugs linked to hosts using FAC AUv3s.
