The RUCE project has been discontinued. We are really, really sorry about it. We suggest you try Moresampler as an alternate.

[ElonSatoshi]

Moresampler requires wine, and seems to be just be a "back-end" or just a resampler for UTAU, so it's not an alternative.

The last commit to RUCE was in 2015. The latest version of UTAU was released in 2013. So as long as RUCE doesn't make Teto sound like a drunk robot, I'm still willing to compile it, if you can tell me how to do so successfully. Or if there's something I don't know, such as it's actually just a backend for UTAU, or it's really hard to use or something, or there's never been a stable version.

Or if there's something I don't know, such as it's actually just a backend for UTAU, or it's really hard to use or something, or there's never been a stable version.

Yes, RUCE is actually just a backend for UTAU. Even if you compiled it successfully, you still need UTAU (or alternatively Cadencii / jCadencii) to use it.

We once prepared to release an independent editor "RocaEditor". But our whole Rocaloid project suspended very soon, for various reasons. I apologize for the inconvenience. It is difficult to reunion our team now. It might take some years before the Rocaloid project relaunches, though we are not deterred.

Anyway, I can still try my best help you if you have any trouble running any other third-party resamplers or wavtool-yawu by Rocaloid. I personally use fresamp, but it is not updating for years, and runs very slow. A LA CARTE is also the plugin worthy to try as it eliminates some unnaturalness.

[ElonSatoshi]

If RUCE is a resampler, and wavtool-yawu is a wavtool, and UTAU is basically just an editor with wavtool.exe and resampler.exe... then maybe I can convert an .ust into sound using the command line, and edit the .ust with vim. Can you tell me how .ust processing works?

[ElonSatoshi]

I'm gonna close this issue. I can compile it if I checkout the nanodesu branch and initialize the submodules. Now if I could figure out how to make it produce a sound file, and how it works, I could perhaps create a script to put together a voicebank, ust, ruce resampler and wavtool. But there's no documentation. But that's for another issue.

For anyone else trying to compile master branch, here's the solution:

 }

Rocaloid is built upon a C based, heavily macro driven customized Object oriented system, this issue took me quite a while to find. I believe this programming mode is also part of the reason why Rocaloid was abandoned... for making the project notoriously hard to maintain. Also a nightmare to any IDEs.

[RigoLigoRLC]

If you happen to use Arch Linux or similar distros, this would be useful for installing a legitimate Rocaloid onto your system: https://github.com/RigoLigoRLC/legacy-rocaloid-pkgbuilds
