2. Setup

2.1 Power Supply

The M-Audio Keystation 88 II is primarily USB bus-powered. This means it receives power directly from your computer's USB port when connected with a standard USB-A to USB-B cable. An optional 9V DC 200mA center-positive power supply (sold separately) can be used for standalone operation or if your computer's USB port does not provide sufficient power.

2.2 Driver Installation

The M-Audio Keystation 88 II is a class-compliant device. This means it is plug-and-play and does not require any specific drivers to be installed for most operating systems, including Windows 8 and Mac OS 10.9 and later. Simply connect the device, and your computer should recognize it automatically.

2.3 iOS Device Compatibility

To use the Keystation 88 II with an iPad or other iOS devices, connect it using the Apple iPad Camera Connection Kit (sold separately). This enables you to perform and compose with audio applications on your iOS device.

3. Operating the Keystation 88 II

3.1 Factory Default Settings Reset

To reset the Keystation 88 II to its factory default settings, follow these steps:

1. Power off the Keystation.
2. Hold down the ADVANCED, OCT+, and OCT- buttons simultaneously.
3. While holding these buttons, power on the Keystation.
4. Release the three buttons once the unit has powered on.

The Keystation is now reset to its factory default configuration.

3.2 Sustain Pedal Polarity

The sustain pedal input on the rear of the Keystation 88 II accepts any standard momentary, non-latching footswitch (sold separately). The polarity of the sustain pedal is determined by the keyboard upon startup. Ensure the sustain pedal is not pressed during startup. If the pedal is pressed during startup, its operation will be reversed (notes will sustain when the pedal is not pressed). To correct reversed polarity, power off the Keystation, ensure the pedal is not depressed, and then power the unit back on.
