There is one option for multi-track recording from a V-Mixing System or Roland Digital Snake:

• Windows 7/8 DAW Recording
  If using a Windows 7 or Windows 8 computer, the REAC driver enables users to capture up to 40 audio channels from a Digital Snake or Roland V-Mixer directly into most ASIO-based DAWs such as SONAR, Cubase, Reaper, etc - all via one Cat5e/6 cable to the PC's Ethernet Port.

    • Notes:
      • Windows 10 and Mac OS X are not supported and there's not a workaround to allow compatibility. The driver has been discontinued and there will be no more updates made to the driver.
      • While the REAC driver was tested in the past with Sonar X1, X2 and X3, we cannot guarantee full compatibility with any other DAW software or version of Sonar.

Note that other previous options for multitrack recording (such as the R-1000 or S-MADI) have been discontinued unfortunately.
