CONNECT MIDI GEAR

Connect your MIDI device’s MIDI IN jack to the

828es MIDI OUT jack (Connection A below).

Conversely, connect the MIDI device’s MIDI OUT jack to the 828es MIDI IN jack (Connection B).

One-way MIDI connections

MIDI devices that do not receive MIDI data, such as a dedicated keyboard controller, guitar controller, or drum pad, only need Connection B

shown in Figure 5-16. Similarly, devices that never

send data, such as a sound module, only need

Connection A. Make both connections for any device that needs to both send and receive MIDI data.

Connecting additional gear with MIDI THRUs

If you need to connect several pieces of MIDI gear, run a MIDI cable from the MIDI THRU of a device already connected to the 828es to the MIDI

IN on the additional device as shown below in

Figure 5-17. The two devices then share the 828es

MIDI OUT port. This means that they share the same set of 16 MIDI channels, too, so try to do this with devices that listen to only one MIDI channel

(such as effects modules), which makes it easier to avoid MIDI channel conflicts.

CONNECT A FOOT SWITCH

If you would like to use a foot switch with your

828es, connect it to the FOOT SWITCH jack. See

item #34 in the Device tab overview (page 14) for

information about how to program the foot switch to trigger any computer keystroke you wish.

SYNCHRONIZATION

If you connect devices digitally to your MOTU device, or if you need to synchronize your MOTU device with an outside time reference such as word clock, you must pay careful attention to the synchronization connections and clock source issues discussed in the next few sections.

Do you need to sync?

If you will be using only your MOTU device’s analog inputs and outputs (and none of its digital

I/O), and you don’t need to resolve your system to external word clock, you don’t need to make any sync connections. You can skip this section.

Situations that require synchronization

There are two general cases in which you will need to resolve you MOTU device with other devices:

■

Synchronizing with other digital audio devices so that their digital audio clocks are phase-locked

(as shown in Figure 5-18)
