Spoiler: Replies 1) Do you mean the utsu-0.3.zip file on the release page? That's a wrapper for the .jar file, so you can debug it by using the instructions on the README page. 2) uh oops Both of those are scheduled for the 0.4 release! Most likely Utsu has a bug and is incompatible with the VCV voicebank you tried. If you were trying to open a published voicebank, can you send me a download link? I can make sure that Utsu's next release is compatible with that voicebank! Thanks for all the bug reports! I tried out Meiji's Fantasy voicebank and it was a goldmine of bugs, I found three bugs whle trying to open it. They have all now been fixed! The "double-rendering" issue has been fixed for next update as well. The Windows issue you mentioned will be harder to debug since I rarely use Windows, but it seems like the Java VM included with Utsu is interfering somehow with the Java VM already installed on your machine. I'll look into fixing the .wav issue you mentioned as well. Didn't even know that bug existed since I've never tried to export anything longer than a few notes. :< Progress report: Utsu is getting a minor update (0.3.1) this weekend. Mostly bug fixes, but there will be a few new UI features and hotkeys as well. Also: yay, 100th post!
