Windows: How to adjust the Latency

On Windows the driver latency is configurable, so that you can optimize for performance. The Apogee Groove Control Panel is accessible from: All Programs->Apogee->Apogee Groove Driver

Under Buffer Settings here are 2 separate drop downs: USB Streaming Mode latency, and ASIO buffer size if you’re using ASIO. The two settings are related, and the control panel will warn you if you try to select an ASIO buffer size that too small for your USB latency setting. The minimum usable buffer setting will vary based on available processing power and other drivers installed. This is something the user may have to experiment with to find the lowest setting that works for them, similar to selecting the buffer size within a DAW.

Windows: What is the USB Device Streaming latency values?

When using Apogee interface with Cubase, Sonarworks, output volume level goes to max.

Symptom: When opening a session or selecting Apogee as the audio device, the output goes to full volume every time.

Solution: 

  • In Cubase, go to Devices > Device Setup > Control Panel > Core Audio Device Settings. Under Options, verify that set device attenuation to 0 dB is unchecked.

NOTE: In Cubase 10 and up, this setting is in Studio Setup > Control Panel

  • In Sonarworks, go to Systemwide settings and deselect the “Adjust output device gain checkbox.

How is this possible? All modern Apogee interfaces have input gain and output volume that are digitally controlled rather than an analog potentiometer that must be physically turned. The advantages of digital control are many:

  • Improved Sound Quality (turning the gain doesn’t cause a “scratchy” sound, and enables the advantages of our Step-Gain preamp technology)
  • Settings can be saved to presets that can be recalled later.
  • You can also control the output volume directly from the Mac’s Keyboard, Touchbar, or Volume icon in the Task Bar.

Cubase:  In Cubase this is called “Device Attenuation.”  The intent of this setting is to attenuate, or lower your volume, so you don’t get blasted.  When selecting any audio device with this setting turned on Cubase sets the device’s output volume to 0, since most simple sound cards have 0 as the lowest value.  Since your Apogee is rating the Outputs in digital decibels, where 0dBFS is the highest value, this setting will have the unfortunate opposite result, maxing out the volume.  Be sure to disable this setting to prevent getting blasted.

Sonarworks Reference 4:  This is a sound calibration software that many customers may have and forget is even running.  It has a setting to Auto adjust output device gain, or volume.

Please remember, many other softwares not listed here have these types of settings so be sure to check all the softwares on your computer!

How do I set my software’s I/O buffer?

The I/O Buffer setting found in most audio software is one of the most crucial, but often ignored, settings in a Mac-based recording system. When choosing a buffer setting, a compromise between the latency through the application and the amount of computer processor power accessible to the application must be made.Latency– the slight delay between the moment you play a note and hear it in your headphones after conversion and processing.

A lower buffer setting results in lower latency but less available processing power. If the application can’t access enough processor power, processor overruns may occur, resulting in audible clicks and pops or error messages that interrupt playback and recording. A higher buffer setting, on the other hand, results in greater amount of accessible processor power (i.e. less chance of overruns) but increases the latency. Determining the best setting requires some trial-and-error in order to find the best compromise.

Keep in mind that as tracks and plug-ins are added to a software session, processor requirements increase. Thus, the buffer setting that works during the early stages of a session might result in processor overruns during later stages. The best strategy is to set the buffer to a lower setting during recording and accept certain limitations on plug-in usage, and then raise the buffer during mixing to utilize the computer’s full processor power when latency isn’t an issue. With the processing power of today’s Macs, you may find that adjustment of the buffer isn’t necessary, and you can leave it at a setting for low latency and still access a sufficient amount of processing power when adding tracks and plug-ins. If you do encounter clicks, pops or software errors, don’t hesitate to experiment with the buffer setting. Please consult the section on Working with GarageBand, Logic and Mainstage to determine how to se the I/O buffer setting is found in your audio application.
