Software for MacOS

Prosody 1.0. This software is still under development and will be available soon.

Vsound 2.7. Fully functional 64-bit version of the Mac software user interface for the vsound 2 effects pedal. For OSX including macOS Catalina. This is currently the latest version of the software.

Installation. It is important to follow the following steps carefully for proper operation of the software:

  • Download and unzip the entire "vsound 2-7 for mac" folder. Place the folder in the Applications folder of your Mac.
  • Inside this folder is the vsound app. Double click to open.
  • Your Mac may not initially permit vsound to open, because it does not recognize the developer. To enable the app, go to the Apple menu icon, and select System Preferences > Security & Privacy. Select the option to run vsound. You only need to do this once.
  • With vsound running, connect your vsound pedal and click "Detect". It should find the pedal immediately. You are now all set to go.
Note: Mac OSX comes with a built-in driver for the USB interface used by vsound. In the unlikely event that it does not have the driver, you can install it from the "vsound 2-7 for mac" folder by running the FTDIUSBSerial.pkg included with your system.
