Q Light Controller+

Please add function

from: XX Hz
to: XX Hz

Why?

to narrow the bandwidth for the "audio trigger" step
(for selected audio input in audio sources)

More than one frequency gives us more problems than benefits.

Thank's and regards!

Please improve your request and explain the usage case.
Do you mean minimum/maximum frequency of the whole spectrum?
Why don't you use only the frequency bars within the range you need?
