More than volume
Three volume keys.
Digital monitor control.

Tested with M4
MOTU M4 reference setup.
F10, F11 and F12 controlled the selected route.
In our studio test, VolumeKeys selected the MOTU M4 as a Core Audio target and the chosen route responded to mute, volume down and volume up. The free trial lets you confirm the same workflow with your own output pair.

How it works
Three steps.
Then use your keys.
Install VolumeKeys, choose your MOTU M interface, and keep using your Mac the way you already do.
Choose your MOTU M interface
Select your MOTU M interface and the stereo output pair shown by VolumeKeys. Available pairs depend on your model, driver and macOS configuration.
VolumeKeys
Use the keys
Press F10, F11 or F12 to mute, turn down or turn up. That’s it.
VolumeKeys with your MOTU M interface
One keyboard workflow for the MOTU M family.
VolumeKeys adds global keyboard and listening tools to Mac playback while MOTU’s meters and direct-monitor path remain hardware responsibilities.
Digital monitor controller
Switch available MOTU M family output pairs. Keep their levels matched.
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
Control level without adding gain.
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
VolumeKeys processes your audio on your Mac.
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
Fade into each saved monitor level.
VolumeKeys fades device and output-pair changes through silence, then returns to the level saved for your MOTU M interface. Each available pair keeps its own remembered level.
Mono check.
Hear both channels together to spot phase and balance problems.
Bass Focus + Night.
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.
Automatic buffer.
Follows the active hardware/DAW buffer without a second competing setting.
Automatic output fallback.
If the selected interface or display disconnects, VolumeKeys automatically returns system playback to the current macOS default output.
Recording
Keep your DAW connected directly.
Select your MOTU M interface in your DAW for recording. VolumeKeys can control normal Mac audio at the same time.
Global shortcuts
Digital monitor control.
Right from your keyboard.
Switch monitor pairs, toggle VolumeKeys, check mono and audition both bass modes from anywhere on your Mac.

Why VolumeKeys helps with the MOTU M family
macOS may show fixed volume.
VolumeKeys restores F10–F12.
A MOTU M interface can play Mac audio normally even when macOS treats its output as fixed-level. When no settable system master volume is exposed, the standard Mac volume keys may be unavailable.
VolumeKeys creates a software-controlled route to the selected output. F10–F12 control routed Mac audio while the MOTU M family hardware keeps its physical monitoring functions.

MOTU M family FAQ
Clear answers for your MOTU M interface.
Learn what happens to metering, direct monitoring, the hardware knob and the playback route selected by VolumeKeys.
Does VolumeKeys work with the MOTU M family?+
VolumeKeys is designed for compatible stereo Core Audio outputs across the MOTU M family. Our documented studio test used M4; the complete 7-day trial lets you confirm your own MOTU M interface and playback pair.
Why are Mac volume keys disabled when the M4 is selected?+
External Core Audio outputs can report a fixed system level instead of a settable macOS master volume. VolumeKeys restores a software-controlled route for compatible output paths.
Does VolumeKeys replace the MOTU monitor knob?+
No. Use the M4’s MONITOR knob for the physical listening level. VolumeKeys attenuates the routed Mac signal and is not designed to boost it above the source level.
Can Logic, Ableton or another DAW use the M4 directly?+
Yes. Select the physical MOTU M4 inside the DAW for recording and low-latency work. VolumeKeys can handle normal Mac audio separately.
