Pro Tools | Carbon ā 11/9/20 5
Loud spikes on the ADAT input of an HD OMNI connected to the ADAT output of a Carbon unit while Carbon is booting.
(PT-265779)
It is possible for loud spikes to occur on the ADAT inputs of an HD OMNI interface (and possibly other devices that support ADAT)
while a connected Pro Tools | Carbon is booting up. For this to occur, the ADAT inputs of the receiving device must be connected to
the ADAT outputs of the Pro Tools | Carbon. If your Pro Tools | Carbon is connected by ADAT to a receiving device, it is recommended
that you disable live input monitoring and/or mute your speakers until Pro Tools | Carbon finishes powering on.
When using Pro Tools | Carbon, no Input Only Monitor signal will be monitored for an Audio Track that is created during
playback until playback is stopped. (PT-267046)
When an Audio Track is created during playback and Input Only Monitor mode is enabled for the track by toggling the track's Track-
Input Monitor button On, the track's assigned input signal will not be monitored for the track until playback is stopped.
When recording using Pro Tools | Carbon, a short audio dropout may occur at the beginning of a recorded clip when printing
through an Auxiliary Input track to an audio track. (PT-267026)
When audio is routed through an Auxiliary Input track to an audio track and recorded on the Audio Track, a short audio dropout may
occur very close to the beginning of the recorded program material. To avoid this issue, either enable DSP Mode on the audio track while
recording, disable both the Audition Path and the AFL/PFL Path in the I/O Setup, or start the record pass earlier in time to avoid dropouts
in the recorded program material.
Apple Display may emit loud noise under certain conditions. (PT-266686)
It is possible for Apple Displays to briefly emit loud noise when switching the Playback Engine between Pro Tools | Carbon and other
devices such as Dolby Core Audio Bridge, Dolby Atmos Production Suite Renderer, and Display Audio.
Headphone outputs stop passing audio after trying to select a different sample rate for Carbon using Audio MIDI Setup while
Pro Tools is open. (PT-266670)
It is possible that no audio is heard through headphone outputs after having tried to change the sample rate of Pro Tools | Carbon in Au-
dio MIDI Setup while Pro Tools is open. If this occurs, relaunch Pro Tools to restore correct functionality.
Bus recording in DSP Mode is offset by a few samples with delay compensation enabled or with a hardware insert. (PT-266502,
PT-266272, and PT-263097)
When bus recording to an audio track from an Auxiliary Input track in DSP Mode, the recorded signal may be offset or improperly com-
pensated compared to the source. With some routing configurations that include internal busses routed to audio tracks or with Hardware
inserts, the audio signal may be offset by a few samples in rare cases. If this occurs, nudge the recorded material forward or backward
in the timeline to correct for this offset.
Switching between Pro Tools sessions with different sample rates can affect bus latency. (PT-263993)
When switching between Pro Tools sessions that use different sample rates, it is possible for bus recording latency to vary between 1
and 3 samples. To avoid this condition, change the Pro Tools sample rate manually to match the sample rate of the next session you plan
to open (quit Pro Tools, then launch Audio MID Setup and use it to set the sample rate for Pro Tools | Carbon). The default sample rate
for Pro Tools | Carbon is 48 kHz.
Enabling or disabling Input Monitoring on a source track in Native Mode during recording or playback results in clicks or
dropouts. (PT-264867 and PT-264857)
Toggling Input Monitoring on a source track in Native Mode can result in artifacts such as clicks or dropouts audible during playback
as well as in the recorded material.
Mixer and plug-in automation missing breakpoints. (PT-266523)
In rare occasions with high-density automation, breakpoints may be missed during playback. If this occurs, thinning your automation
will resolve this.
