UMIDI(4)                  OpenBSD Programmer's Manual                 UMIDI(4)

NAME
     umidi - USB MIDI devices

SYNOPSIS
     umidi* at uhub?
     midi*  at umidi?

DESCRIPTION
     The umidi driver supports USB MIDI devices that follow the USB MIDI stan-
     dard.  It also supports the following vendor specific devices:

           Roland UM1
           Yamaha UX256
           Yamaha UX96
           other Yamaha MIDI devices (hopefully)

     The umidi driver is accessible through the midi(4) driver.

SEE ALSO
     midi(4), uhub(4), usb(4)

HISTORY
     The umidi driver appeared in OpenBSD 3.2.

CAVEATS
     Some USB MIDI devices provide a switch for selecting between a vendor
     specific mode and standard USB MIDI mode.  Selecting standard USB MIDI
     mode may allow a device to attach as umidi rather than ugen(4).  This is
     particularly true for Roland branded devices.
