VL ONE70 (beta) is a Macintosh OS X-compatible (PowerPC only) software librarian for Yamaha's VL series synthesizers. This software is meant to help you organize and edit your patches (“voices”) and converting them between the VL1 and VL70 synthesizers. In addition it offers a complete “Expert Editor” style interface for in-depth editing of the VL1.
For the VL70, it can convert the otherwise inaccessible PR and INT formats (rom and internal, respectively) to the less restrictive CST (custom) format. It therefore allows you to download and manage VL70 voices based on their internal roms.
Lastly, it is the only software that can convert between VL1 and VL70 voice formats, allowing your favorite voices to be played on either synthesizer. Finally, play your favorite VL70 voices on the clearer , cleaner, more transparent, more responsive VL1.
