Hello MV-Nation. So far I'm using Translator to create .mv0 files. I can create a .mv0 from a directory with 50 .wav files and under. Simply right click the directory you choose to convert with default settings and you will have a big .mv0. To get more that 50 .wav file converted into on .mv0, you will have to create a .pgm within the directory. I have used MPC Software to create my .pgm. You would drag and drop your directory with 50+ .wav files to pad one. Then export the .pgm to the desired location. Once that's done you can use Translator to convert your .pgm to .mv0.
Software used:
-Translator v2.9
-MPC Software v1.9.6
Hardware used:
-MV-8000 v3.54
