Problems Using USB-MIDI to Connect to a Computer Music Application

I am trying to connect my SP2 to my computer via USB and am having troubles with it being recognized. How do I fix this?


Though not all, most USB-MIDI issues are simply a matter of making sure you are running the most current OS on your SP2. Earlier revs may be limiting the platforms supported.

You can check to see what version of OS your SP2 is running simply by powering up. Briefly in the display during boot up, you will see a 3-digit revision number displayed, v1.XX.

The latest version of the SP2 OS is available online at the model links below:

Select your specific model above, Click OS UPDATES. Download and install the current update (instructions included).

Platform Specific Notes:

Windows Users:

If you are updating from SP2 OS v1.07 or older using USB, Windows XP must be used. Alternatively you can simply use traditional MIDI connections to update your OS. Once updated, Win7, Vista and XP can be used for future updates over USB.

A word about USB Drivers: The SP2 Series supports "plug n' play" operation, using Window's own built-in generic MIDI driver. No proprietary USB MIDI driver is required.

For XP users though, as a convenience, we do offer an SP2 Series Device Installer (available at the same links above) but it is completely optional. The installation of this driver is simply a naming convenience, permitting your host DAW to reference the SP2 unit by name ("Kurzweil SP2 MIDI") versus Window's generic "USB Audio device" driver label. Neither Win7 nor Vista make use of such label drivers as they generate the device name inherently.

Mac OSX Users:

v1.01 of the "Boot Block" (SP2BootV101.mid) is required for USB updating functionality (included in the OS update download). If you are currently running less than v1.01 of the boot block (the boot block version number is displayed on screen upon entering the boot block menu), you must update the boot block via traditional MIDI connections first before you can use USB to update the OS. Alternatively you can simply use traditional MIDI connections to update your OS and not use USB for updating.

The SP2 Series supports "plug n' play" operation. No proprietary USB MIDI driver is required.
