If you recently purchased a Presonus 1818vsl you may have noticed this error message after plugging it in to your iPad via the Apple Lightning to USB Camera Adapter.
Presonus ships their products with an older firmware. To update the latest firmware just follow these steps:
1) Go to the Presonus website to download the AudioBox VSL Software.
*As the website suggest you won’t be able to download with a computer on El Capitan and has to be at least be on the OS Mountain Lion.
2) Install the software
3) Plug in your 1818vsl and it will prompt you to update the firmware
Note: You may need to plug in to a USB 2.0 port on your computer. There have been instances where USB 3.0 have been incompatible.
