VolumeKeys with your Focusrite Scarlett interface
Use Focusrite Control 2 for hardware routing. Use VolumeKeys for fast Mac playback, matched stereo-pair changes and global mix checks.
Digital monitor controller
When the device and driver expose more than one compatible stereo pair, VolumeKeys can remember a separate level for each available pair and switch between those selected routes.
High-precision 32-bit floating-point volume processing designed for transparent monitor control.
Digital attenuation
VolumeKeys attenuates the routed Mac signal and is not designed to add gain above the source level. Set your interface or monitor control for the physical listening level you want.
Private by design
Your audio is processed locally and is not sent to our servers by VolumeKeys. The app contains no ads or app-usage analytics.
Controlled changes
VolumeKeys fades device and output-pair changes through silence, then returns to the level saved for your Focusrite Scarlett interface. Each available pair keeps its own remembered level.
Hear both channels together to spot phase and balance problems.
Focus isolates everything below 150 Hz for precise low-end decisions. Night focuses its processing where bass becomes physical. A purpose-built low-frequency DSP algorithm reduces the deep energy that makes rooms and walls vibrate while keeping the musical body of the mix intact. You hear a full, balanced sound at night, while less bass travels next door.
Follows the active hardware/DAW buffer without a second competing setting.
If the selected interface or display disconnects, VolumeKeys automatically returns system playback to the current macOS default output.
Recording
Select your Focusrite Scarlett interface in your DAW for recording. VolumeKeys can control normal Mac audio at the same time.
Global shortcuts
Switch monitor pairs, toggle VolumeKeys, check mono and audition both bass modes from anywhere on your Mac.
Only available output pairs get a shortcut. Each global shortcut is registered independently, so a conflict on one shortcut does not disable the others.

No. Those remain responsible for the Scarlett’s hardware routing and monitor level. VolumeKeys controls the routed Mac signal digitally before it reaches the selected output.
If VolumeKeys shows more than one compatible stereo output pair, you can switch between them, for example between two connected pairs of studio monitors. Focusrite Control 2 continues to handle the Scarlett’s internal hardware routing.
