6.30 How to use MIDI without the MusicKit?

• Be sure you have an MPU-401 compatible MIDI card for the PC.

• Get the Music Kit and install it. It's on the ftp servers.

• Install the MIDI driver by double clicking on /LocalLibrary/Devices/Mididriver, which will add it to the system. Set the IRQ and IO port in the Configure.app. Then reboot.

• If your program does not use the -ObjC flag on its link line, link against /usr/local/lib/libmusickit.a. However, if your program does use the -ObjC flag, extract the following files from libmusickit.a and link against them

  explicitly:

  mididriver_replyServer.o mididriverUser.o mididriver_nonMig.o

• Add this line as the first line in the C file that accesses the MIDI driver:
  #import

  Be sure that you do not explicitly import . This file is (conditionally) imported by .

  The reason for needing a separate API for Intel is that there's a structure size disparity between the 68k and Intel versions of NeXT's libsys_s. So we defined a new set of MIDI functions for the Intel driver. The header file above defines the old names to be the new names.

• Change the mididriver port name from mididriver to Mididriver.

  Example:

  #if i386 #define MIDIDRIVER_NAME "Mididriver" #else #define MIDIDRIVER_NAME "mididriver" #endif r = netname_look_up(name_server_port, "",MIDIDRIVER_NAME, &driverPort);

  This is another change to prevent conflict with the NeXT hardware driver.
