Updating from v1.x to v2.x

  • Upgrading from v1.x to v2.x requires you to remove all user data from disk. A prompt will guide you through the process—no data will be deleted automatically.

  • When prompted to wipe the S-4, the device will automatically enter USB MASS STORAGE mode. Simply connect it to your computer via USB to back up your files.

  • The v2.x installation cannot proceed if any user samples, recordings, or projects remain on the S-4.

  • When the installation is complete, you can transfer any user samples, recordings and projects back on to the S-4.

I have followed the update steps, but I can’t update my unit.

  • The S-4 requires a .zip file for performing firmware updates. Please make sure not to unzip the downloaded file before transferring it to the S-4.

  • Re-zipping the firmware once it has been unzipped will not work.

  • We frequently encounter issues with Safari automatically unpacking zip files post-download. To prevent this, please uncheck the box in Safari called “Open files after downloading” in - > Settings -> General

  • Make sure the file isn’t a duplicate. Duplicate files will be named with a number in a parenthesis. E.g. S-4-OS-v1.2.2 (1).zip

  • Empty the trash - not enough space can cause the error

My S-4 won’t go into USB mass storage mode, what can I do?

  • Use RECOVERY mode to boot your S-4 into USB MASS STORAGE.

  • Power down the S-4. Connect a USB-C data cable from your computer to the S-4, and power on the unit. Under [SYSTEM] select USB MASS STORAGE.

  • Connect your S-4 directly to the computer without a USB hub.

  • Flip the USB cable.

  • Make sure to use a USB-C data cable and not a USB-C power cable to connect to your computer.

  • Make a power cycle (Unplug and replug the power supply).

  • FACTORY RESET the unit.

If your S-4 unit still won’t go into USB MASS STORAGE mode, contact our support mail: [email protected]

Support of external USB drives

  • Make sure to format to FAT32

  • Use a recent and fast drive for best performance

  • Avoid connecting through a USB hub

I’m using sends to another track on the S-4, but there’s no sound

In Track View, ensure that the track is correctly routed to another track. The receiving track must be either a Material device set to BYPASS, or a DISC or TAPE device set to Monitor mode.
