Have you ever wanted to run useful job plugins only to find out you couldn't run them since V5 ?
Have you ever wanted to see the cute face of miku staring at you while you're producing ?
Well you're in luck ! Because Betterloid is here !
Betterloid is compatible with both VOCALOID5 and VOCALOID6 on Windows and works both in standalone and VST mode !
What is Betterloid?
To put it simply, it is a mod that enables plugins on VOCALOID 5 & 6. There are two types of plugins supported :
- Startup Plugins : These plugins are activated automatically when the vocaloid editor starts. This is what the background plugin uses.
- Editor Plugins : These plugins add an option in the Plugins tab at the top of the editor. This is what the JobPlugin plugin uses.
Is it legal?
Betterloid works by replacing the Newtonsoft.Json.dll file in the VOCALOID install directory by one that loads custom code.
Newtonsoft.Json.dll is an open source json library that is used by vocaloid.
The source code of the library with its license can be found here : GitHub - JamesNK/Newtonsoft.Json: Json.NET is a popular high-performance JSON framework for .NET
Betterloid does not disable any of the anti-piracy features of VOCALOID, it is still required to purchase a valid copy from Yamaha to use the software. As such it does not infringe on copyright.
What can it do ?
With betterloid, you can do lots of things. You can edit the piano roll background to look however you want, you can disable the auto pitch tuning of V6, and you can use tons of job plugins such as Expressive Vibrato, Electronica Tune, AutoVibrato, Vocaloid Pit Helper and many more which extend quite a lot the feature set of these editors !
I'm also ready to hear suggestions of potential features to add. so don't hesitate to suggest things !
How do I install it?
First, ensure you updated to the latest VOCALOID5 or VOCALOID6 version. All betterloid versions are compatible with the latest V of vocaloid 5
Latest versions as of the time of writing :
Betterloid : 16-09-2026-r1
Vocaloid6 : 6.13.3
Vocaloid5: 5.7. 2
Download 9.35 MB folder on MEGA
The versions are numbered by the release date in french date format. so for instance 15-09-2026-r2 means "September 15th 2026 Release 2". (the Release 2 means it's the second version posted the same day)
so basically, the latest version is the version with the most recent date and the highest release number.
If you want to use Betterloid with old Vocaloid6 versions for some reason such as vocaloid 6.4.3, then please use the 2024 version. It however will lack new features and bug fixes.
When downloading, you may need to unblock the zip before extracting, not doing so may result in files from betterloid being blocked by windows and as such causing crashes. To do so, right click the zip go to "properties", then check the "unblock" option in the properties then "Apply"
Once extracted you will have two folders. A folder named V5 and a folder named V6.
As the name implies you will need to copy the content of each folder to the appropriate vocaloid version. If you own V6 you will copy the content of the v6 folder to where VOCALOID6.exe is located, while if you own V5, you will copy the content of the v5 folder to where VOCALOID5.exe is located.
you'll be able to verify the correct install if the Plugins tab appears on top of the vocaloid editor when you start it.
Once you'll be done with it, you will have installed Betterloid as well as the JobPlugin plugin allowing you to use V3 and V4 plugins. (Not every plugin will work. I do my best to provide as much support as I can, but it's still an unofficial project trying to reimplement undocumented features. If you can't get a plugin working, please let me know and I'll check if anything can be done about it).
How to update Betterloid
Currently, Betterloid doesn't have a dedicated installer or updater, so updates must be done manually.
You can check your current version by going to "Plugins > About Betterloid". This should display the version you're currently on.
if your version is older than the latest released version, then just delete the Plugins directory, and the files Newtonsoft.json.dll and Betterloid.json from the vocaloid editor directory, and then extract the ones from the up to date version. (If your version displays Betterloid 1.0 or 2.0 instead of a release date, then your version is severely out of date).
If you install a vocaloid update, you most likely will need to reinstall betterloid, or at the very least, replace the newtonsoft.json.dll as updates are likely to restore the original one.
Can I update Vocaloid ?
In most cases, Yes ! You can keep updating your vocaloid install just fine. I however recommend waiting for an official confirmation that Betterloid actually works on the new version before updating, simply by safety, as while betterloid is programmed in a way that should be future proof, if yamaha changes too much the internal API of vocaloid in an update, some features can break.
If updating vocaloid, you may need to re-apply the betterloid files to it, simply because the vocaloid updater basically reinstalls vocaloid, and as such restores its installation files to its defaults. removing betterloid's hook (newtonsoft.json.dll) in the process by restoring the original.
