was always annoyed that the audio level of usb audio interfaces on macos could not be controlled via keys and you had to manually reach for the physical knob
vibed a little app to give that feat to my audient id4 today 🙂↕️
i feel at peace
note: this doesn't modify any macos volume or anything, it just sends a new level to the interface itself—which the id4 understands because it has a rotary encoder
