Connect your MIDI equipment

If you are using a MIDI interface (such as an MPU-401 or Sound Blaster MIDI option) with an external MIDI keyboard, you need to connect the equipment using MIDI cables.

It is possible to connect your equipment in some rather complex ways that may cause problems. If you call for technical support with a problem concerning equipment that doesn’t seem to be responding, we’ll probably suggest that you reconnect things in one of the ways listed here before we explore the problem further. Also be sure to check the Troubleshooting chapter before calling us.

There are two methods that fit many circumstances. The one you choose depends on whether your keyboard has:

All three types of MIDI jacks: In, Out, and Thru

Only two types of MIDI jacks: In and Out

If you have only one keyboard, read If your keyboard doesn’t have a MIDI Thru jack (regardless of whether you have MIDI Thru or not).

If your keyboard has a MIDI Thru jack

If your keyboard has three MIDI jacks—In, Out, and Thru—then use the following diagram.

If you are using a 15-pin joystick adapter cable that splits into two MIDI cables:

Connect the 15-pin jack to your computer’s joystick port.

Connect the In cable to your instrument’s MIDI Out jack.

Connect the Out cable to your instrument’s MIDI In jack.

Here’s a checklist:

Table 236.  

Connect this	To this
Master keyboard Out	MIDI interface In
MIDI interface Out	Master keyboard In
Master keyboard Thru	Another MIDI module’s In
That MIDI module’s Thru	Yet another MIDI module’s In

Continue the sequence, repeating the last connection for each of your sound modules.

Each MIDI device should be set to a unique MIDI channel or range of channels to avoid note-doubling. Refer to the manuals for your MIDI devices for information on how to set their MIDI channels.

Your MIDI interface may have a Thru jack as well as In and Out jacks. If your master keyboard lacks MIDI Thru, you can add more MIDI modules to your setup by connecting the MIDI interface’s Thru to the first module’s In. You can then chain subsequent modules onto the first module, as described earlier.

If your keyboard doesn’t have a MIDI Thru jack

If your keyboard has only two MIDI jacks—In and Out—or if you have only one keyboard, use the following diagrams instead:

Each MIDI device should be set to a unique MIDI channel or range of channels to avoid note-doubling. Refer to the manuals for your MIDI devices for information on how to set their MIDI channels.

If your master keyboard now seems to double notes (they sound thicker), or if you can play only one half as many at once, first make sure that no MIDI channel is being used by more than one of your MIDI devices.
