I bought recently a Roland  SP 555 SAMPLER.   I like this specific model, because it has a "loop capture" feature making sampling live more easy.  But guess what ?  DRIVERS ARE NOT WORKING UNDER WINDOWS 10.

Why do I need drivers you think ?  THE SP 555 can be used as a sound card with a specific USB driver, and it works with ASIO also.  So when  you play a sound file on your computer, you can sample directly via USB, without degrading the quality of the sound.  On the other hand, it is more usefull than filling the CF card in "blind" mode.
+ the USB can be also used as MIDI IN/OUT.
+ updates  need USB MIDI

Spending one hour to test all drivers versions, WIN7, WIN7 64bits, VISTA, XP, WIN8,...nothing worked.  The SP 555 was here in the device manager, but with the infamous question mark...

So I spent one more hour to modify the .INF files of the WIN7 64 bits version, disabled the driver protection mode of WIN10, and everything is now working like a charm !!!

- SP-555 is recognized by Windows
- The SP-555 is seen as a sound card
- I can use the windows mixer to set the default output to SP 555
- MIDI IN and OUT is perfectly working with USB : I did the update to 1.4 version

Procedure to install drivers on Windows 10 - 64 bits:
  • Turn OFF SP-555 and connect it with a USB cable to your computer
  • Open a CMD window in admin mode and accept the warning from Windows (type CMD on the search bar and use the right click to launch in administrator mode)
  • Give the following 2 commands:
    bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
    bcdedit -set TESTSIGNING ON
  • Reboot your computer
  • Turn on SP-555 and open device manager and look for SP-555 "unknown device"
  • Download drivers modified by me HERE
    (ignore the error message if you have one and click on Download)
  • Unzip files with 7ZIP in a directory of your choice
  • On the device manager, on SP-555 device,  right-click->properties->driver->update->don't search->have disk and goto folder where you extracted the driver. Ignore the warnings in RED and install.
  • Return to the initial state of signed drivers by opening again a "cmd" as admins and give the following 2 commands:
    bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS
    bcdedit -set TESTSIGNING OFF
  • Reboot the system
    Done !
