5. Operating Instructions
This section details the basic operation of your Keystation 88 MK3.
5.1 Playing the Keyboard
Once connected to your computer and with your DAW or virtual instrument software open, the 88 velocity-sensitive keys will transmit MIDI note data. The velocity sensitivity allows for dynamic expression, where playing keys harder results in louder sounds, and softer playing results in quieter sounds.
5.2 Using the Controls
- Volume Fader: Move the fader up or down to control the assigned parameter, typically master volume or an instrument's volume.
- Pitch Bend Wheel: Move the wheel up or down to bend the pitch of notes. This effect is temporary and returns to center when released.
- Modulation Wheel: Move the wheel up or down to add modulation effects, such as vibrato or tremolo, depending on the virtual instrument's settings.
- Octave Up/Down Buttons: Press the 'Octave +' or 'Octave -' buttons to shift the entire keyboard's pitch range up or down in octave increments. The current octave setting is indicated by LED lights.
- Transport Controls (Play, Stop, Record, Fast Forward, Rewind): These buttons send standard MIDI Machine Control (MMC) messages to your DAW, allowing you to control playback and recording functions directly from the keyboard.

5.3 Sustain Pedal Input
Connect a standard 1/4-inch TS sustain pedal (not included) to the Sustain Pedal input on the rear of the Keystation. This allows you to sustain notes, similar to a traditional piano.

After installing the included software, ensure your DAW or virtual instrument is configured to recognize the Keystation as a MIDI input device. Refer to your software's documentation for specific MIDI setup instructions.
7. Maintenance
To ensure the longevity and optimal performance of your Keystation 88 MK3, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the surface of the controller. Avoid abrasive cleaners, solvents, or waxes.
