Device Overview

Name/Version: VU Meter 1.0.1
Author: Funkatronics  
Description: An Ableton-esque VU meter that tries to model the behavior of older analog VU meters while adding some more modern features.

It is essentially an RMS meter with a long attack/release time that is useful for gain staging and quick leveling of tracks. Features a channel split mode for viewing the left/right or mid/side channels simultaneously, nominal (reference) level adjustment, adjustable attack/release, a floating window, and a proper L/R phase correlation meter.

Note: this is not a loudness meter and therefore not the proper tool for measuring the loudness of your mixes. For loudness measurements, check out my Loudness Meter device here:

No way, this is fantastic! :D Such a great tool to help with proper gainstaging. I will keep it as a default on my master.

Thanks a lot for sharing your work. :D

Thanks @ekaku! Its always a pleasure to see my work being used. Good luck your productions!

This is really useful. Unfortunately, when it is running it fills up the undo list in Live with Change "live.numbox[8]".

Hey, love love love the meter, but its as Bubbleandsquawk said, when running it somehow is hooking into the UNDO function. so while its running, say if you delete a clip or anything that should be undoable by command /control -Z, you are unable to because the undo buffer is filled with the VU meter activity.

Can u take a look sometime? Its a brilliant and super useful max device, but ruined by this one bug.

thanks in advance!

@bubbleandsquawk and bonkorama, sorry for the delay, I will look into this issue ASAP!

I believe I have fixed the issue with the undo history getting borked. Try out version 1.0.1 and let me know how it works for ya.

Sorry again for the delay on this bug fix!


There's still a numbox filling up the undo

Hey, great device! I use it for gain staging.

Noticed a possible bug though. When extending the plugin to split the left and right channels it seems like the right channel is giving an incorrect reading when viewing from the rack. However, it gives the correct reading when you open the plugin itself... Here's an example. Using version vu-meter 1.0.1 with Live 10.1 on MacOS 10.14.5.

Same for mid/side too actually.

Hi @bigwitch. Sorry for the bug you are experiencing. I have been trying to reproduce this issue so I can find a fix, but I am not able to replicate what you are seeing. Without reproducing the problem, it can be really difficult or impossible to debug these sorts of issues. Also, I am a Windows user, and don't have access to a Mac for testing/debug. Hopefully this isn't a Mac specific problem.

Could you send me a simple Live set that reproduces the issue using stock Ableton plugins (just to make sure I have the right instruments to run the set)? You can send it to my email at

Sorry I can't be of more help at the moment, I would like to get this issue fixed for ya. Thank you for the feedback and for using my device! I really appreciate it!

Hi @Funkatronics,

Just tried to make a Live Set for you but I was unable to reproduce the error. Everything seems to be running perfectly now. Must have been something to do with my version of Live as that's the only thing I have changed (I'm now running 10.1.14). Unfortunately, I did not give the subversion number last time so unsure which version might have been causing the issue so sorry about that.

Thanks again!

Great idea but the reading is not accurate; i know it says it's an RMS meter... yet it also displays an old type of VU meter... well neither are accurate as compared to SPAN, Ozone, or Abletons own in program readings; so really I don't know what this device is reading

This device is fantastic, I needed something native for the gain stage in ableton and not have to open multiple plugin windows for staging within each channel in ableton, just I would like to know if the funkatronic guys still give support in case of having problems in new live 11,1

I would even pay for this small device to have support today, thank you guys :)

Hey there! Just tried out this device today, and it is absolutely brilliant and handy. However, right now it's not showing the same levels as Ableton's own gain meters, and it's more than 6db difference. Is this a bug?

I tried a couple things, but haven't been able to make it give the same values.
