Before You Connect:

Before you connect your keyboard, please note: While you can power the keyboard via either USB or optional external power supply, in order to avoid damaging the unit, use only one method at a time.

Power Connection - USB or External Supply

You can power the keyboard either via USB or using an external power supply. To power via USB:

1.Check that the on/off switch (18) on the back of the unit is set to “Off.”

2Plug the USB cable provided with the Keystation Pro 88 into a free USB port on your computer.

3. Plug the other end of the USB cable into the USB socket on the Keystation Pro 88 (13).

Note: The USB cable not only powers the keyboard, but also sends MIDI data to and from your computer system.

To power using an external supply:

1.Use a power adapter (not included) with the following specifications: 9V DC output, 250-300mA, center positive.

2.Make sure you are not already powering the Keystation Pro 88 via USB, and then simply plug the power supply into the jack labeled DC 9V (19) and switch the power on (18).

Note: Do not leave the adapter plugged in for long periods of time if the unit is not in use.

MIDI Connection - In and Out Ports

On the rear panel of the keyboard you will find a MIDI Out port (14) that you can connect to an external sound module or MIDI keyboard. By default (when you switch the unit on), all controller data is sent out via the MIDI Out and the USB Out simultaneously.

If you want the MIDI Out to function as a traditional USB-to-MIDI interface, engage the “MIDI Out from USB” mode by pressing dual function buttons (PROGRAM and DATA LSB) labeled for this action. This is further explained in Advanced User Guide. The MIDI In port

(15)can be used to connect external MIDI devices to the PC. The MIDI In port acts as a USB-to-MIDI interface. Both the MIDI In and MIDI Out ports and their functions are further explained in the Advanced User Guide.

Windows XP and Mac OS X

If you are running Windows XP or Mac OS X, connecting the class-compliant Keystation Pro 88 to your computer via USB cable will cause it to install automatically. You may now move the On/Off Switch on the back of the unit to the “On” position.
