I/O Setup, Output page Main and Alt Monitor Paths The Main monitor output path and the two Alt monitor paths can be enabled or disabled in the Hardware Setup. When enabled, each appears color coded in the Output page of the I/O Setup.
DSP Mode for Low-Latency Monitoring DSP Mode ensures that low-latency monitoring is maintained during recording with Pro Tools | Carbon. You can enable or disable DSP Mode on a track-by-track basis. DSP Mode can be enabled for Audio, Auxiliary Input, Instrument, Routing Folder, and Master Fader tracks.
Enabling DSP Mode Enable DSP Mode on tracks for low-latency monitoring during recording or input monitoring. With DSP Mode enabled: Protecting low latency is the highest priority. The track and its entire signal chain run on the HDX DSP in Pro Tools | Carbon. Any plug-ins on the track that are not available in DSP format are bypassed. HEAT is not supported on audio tracks in DSP Mode. In the Mix window, HEAT is bypassed for all audio tracks in DSP Mode.
Enabling DSP Mode Safe Use DSP Mode Safe to prevent DSP Mode from being automatically enabled on a track. This is useful if you want to route any audio from a DSP Mode–enabled track with any plug-ins that are only available in Native format. For example, you might want to send audio from a DSP Mode–enabled audio track to a DSP Mode Safe–enabled Auxiliary Input track for processing with a reverb plug-in that is only available as a Native plug-in.
DSP Mode Insert Indicator Plug-in Insert selectors change color to indicate whether DSP plug-ins are inserted on a track that is DSP Mode enabled or DSP Mode auto-enabled, or if a plug-in has been made inactive due to insufficient DSP resources.
DSP Mode, DSP plug-in inactive due to insufficient DSP resources DSP Mode, Key Input inactive due to insufficient DSP resources Send Selector DSP Mode Indicator When a Send is made inactive due to insufficient DSP resources, the Send selector appears dark orange and any text is italicized.
System Usage The System Usage window in Pro Tools provides a Pro Tools | Carbon pane that lets you monitor the number of available AVB Input and Output channels in use, and how much DSP is being used by plug-ins and the mixer. System Usage window, Pro Tools | Carbon pane Input Channels Shows the number of AVB channels dedicated to audio streams from Pro Tools | Carbon to Pro Tools. Output Channels Shows the number of AVB channels dedicated to audio streams from Pro Tools to Pro Tools | Carbon.
Workflow Example: Recording in DSP Mode for Low-Latency Monitoring The following workflow example uses DSP Mode for recording a singer with DSP plug-in processing and low-latency monitoring. This example session is made up of the following tracks (see the graphic on the next page): • 3 mono audio tracks for vocals, guitar, and bass. Each track has EQ and dynamics plug-ins, and the vocal track also has a slap-back delay. • 2 stereo audio tracks, one for electric piano and another for drum loops.
Adjust the Mix for Recording Start playback to set the levels and panning of the instruments to get the mix you want in the control room monitors. Set the send levels from each track to balance the headphone mix. Input-enable the vocal track and use the talkback mic to communicate with the singer and adjust the headphone mix to the singer’s liking. Once the singer is happy with the headphone mix, you are ready to record some vocals.
Record with Low-Latency Monitoring Enable DSP Mode on the vocal track. Notice that all tracks that are part of the signal chain for the vocal track have DSP Mode enabled automatically: the reverb Auxiliary Input track and both Master Fader tracks. All plug-ins on these tracks switch from Native to DSP format (any Native only plug-ins on any of these tracks are automatically bypassed). Record-arm the vocal track, and when the singer is ready, start recording.
Use DSP Mode Safe to Record with Native Reverb Let’s assume that you have a Native-only reverb plug-in that you really like. You can still record vocals with virtually no latency in their monitor mix while still using your favorite Native-only reverb plug-in to process all of the audio tracks. Enable DSP Mode Safe on the reverb track and set the wet/dry mix on the reverb plug-in to 100% wet.
Tips for Using DSP Mode To ensure optimal workflows in DSP Mode: Use input and output gain controls on Native-only plug-in inserts to make up for any undesirable changes in signal level when switching between Native Mode and DSP Mode. Since DSP Mode does not reduce latency for tracks that are not part of a live signal path, avoid enabling DSP Mode on tracks that are not part of the signal chain for recording and input monitoring.
