MIXING & EFFECTS

Mixer Track Panel

This section covers the Mixer Track panel. Only one Mixer Track panel can be seen at a time. It integrates a parametric equalizer, PDC (Plugin Delay Compensation) and hardware audio INPUT/OUTPUT controls.

NOTE: The integrated effects are the last processing/FX stage prior to audio leaving the Mixer Track and so follow any plugin FX loaded into slots.

Plugin Delay Compensation - PDC

PDC is required when plugins (instrument or effects) have processing delays that put their audio out of sync with other audio in the project. Most commonly effects introduce these unwanted delays and this causes the audio on their Mixer Track out of sync with other Mixer Tracks. PDC works by adding this same delay to all other Mixer tracks, to bring them into sync again. When several plugins introduce unwanted delay on several Mixer Tracks then multiple compensations are required so that all the tracks end up in sync when the audio reaches the Master Mixer track.

The Delay Panel (B) is available on all Mixer Tracks. This will turn orange when a delay is detected on that Mixer track, either from instrument Channel/s routed to that track or from effect/s loaded on the track. You can also click the icon to make manual adjustments to PDC (Automatic PDC will still operate in addition to these changes). Manual PDC is required when plugins don't report their processing latency correctly or at all. Enter positive values to add delay to the Mixer Track or negative values to add latency to all other tracks. If you need to set up PDC manually, a tutorial is provided in the next section.

NOTES:

  1. The PDC icon will show orange for Mixer tracks with detected plugin latency OR where PDC has been manually set. Hovering your mouse over the PDC icon will show the detected latency in the Hint bar.

  2. When using PDC, FL Studio will no longer respond 'instantly' as the audio output is delayed to sync with the PDC latency.
  3. Automatic PDC now works for both Generator and Effect plugins.
  4. APDC also applies to inter-track routing and sidechains.
  5. Manual and Automatic PDC can be used together.
  6. Positive manual latency values will delay the selected track, negative values delay all other tracks.

Guide to Manual PDC - Instruments and Effects

Normally Automatic PDC should work. If not, Mixer Tracks containing Instrument and or FX plugin that introduce unwanted delay (delay-affected) will be out of sync with the other Mixer Tracks. Manual PDC is no more complex than delaying all 'normal' tracks by the same amount as the delay-affected track, bringing the two audio streams back in sync. To facilitate manual PDC, a highly accurate compensating delay is available through the Mixer Track Delay Panel (B). These will act as offsets to Automatic PDC if it is left on (recommended).

Step-by-step instructions to using Manual PDC:

  1. Switch Automatic PDC on (Mixer Menu > Plugin delay compensation > Automatic) - This will make PDC management easier if things change in the project (and they usually do).
  2. Delay-affected (slow) plugin/s - Route the delay-affected instrument to, or insert delay-affected plugin/s on an FX slot of any Mixer Track.
  3. Determine the delay compensation - Normally this is shown in the hint bar when you hover over a plugin FX slot that contains a plugin causing (and reporting) a delay. However, as this is incorrect you will need to use trial-and-error to set the PDC. Use positive values to delay the selected Mixer Track (the plugin is early), use negative values to delay all other Mixer Tracks (the plugin is late).
  4. Testing - In the case of an instrument, set a short, sharp sound and compare it with a similarly short-sharp sound on another Mixer track (with no FX). In the case of an effect set up two Channels and route the same kick or hat sound through the delay affected track and a normal track without FX. Play the sounds together and adjust the PDC control until the sounds from the delay affected and normal Mixer tracks are in sync/phase (you can adjust down to the level of single samples).
