If you do not find an answer to your questions, mail ➞ support••fredantoncorvest•com

This page is your primary resource for quickly resolving common issues. Check out the list below to learn more about known issues and their solutions. This will ensure that your music creation journey stays as smooth as possible

• iOS | The plugin cannot be found by your host

  • 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)

• iOS | The plugin does not produce any sound (muted)

  Reset the Buffer Size setting on your host to 512, for instance, and try again

• iOS | 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

• iOS | Multi selection of files/folders in FAC Drumkit

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

• iOS | 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

• iOS | FAC Envolver works fine as Audio fx but no MIDI OUT

  In order to output MIDI messages, your host must provide a valid MIDI output block to the AUv3 (AUMIDIOutputEventBlock)

  FAC Envolver is a MIDI/AUDIO fx and can be used 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 only be used as a standard AUDIO fx

  If you still have issues in a host providing a valid MIDI output block, check the following points:

  • Have you disabled the MIDI out? Both slot buttons (|1/ and |2/) can be toggled (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

• macOS | The plugin cannot be found by your host

  Logic Pro, Ableton Live, Garage Band, Reaper, Hosting AU, and Wotja are the only ones that allow loading AUv3 plugins (as far as I know)

• macOS | Logic Pro: The plugin is not listed in a mono audio channel

  Toggle the audio channel mode from mono to stereo. The list will be updated, choose your plugin

• macOS | Logic Pro: The plugin does not produce any sound (muted)

  Go to the general Audio Settings

  • Reset the Buffer Size to 512 for instance, or
  • Set the Process Buffer Range to "Small" or "Medium"

• macOS | 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...

• iOS, macOS | "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

• iOS, macOS | 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
