General

   JVTool is a graphical tool/editor for the Roland JV-series keyboard. Using SysEx message, it communicates with the JV keyboard to download and upload data. SysEx data can also be saved to / loaded from disk files, for easy exchange with other users. JVTool provides an intuitive graphical environment to edit all the parameters of the keyboard, including a fully graphical envelope editor, a wave selector, cursors, and many more (see screenshots section).

   Currently, JVTool only supports edition of patches and banks (group of patches), but it is planned to become a complete edition tool for JV keyboards, including Performance and Rythm editors.

   JVTool runs under Windows and Linux, is written in C++ and based on the Qt toolkit (http://www.trolltech.com). It is free (BSD license), and only requires free components. It has been currently successfully tested under the following systems (see the Requirements section for more information):

  • Linux
  • Windows
  • Windows/cygwin
