Our primary goal is to reduce the need for keyboard and mouse during a music composing task. We accomplish this by moving the
most commonly used computer keyboard macros and mouse functions to the MIDI controller keyboard. This
allows the composer to work more efficiently. An example of a macro that can be relocated to the
controller is the copy function, or [Control]-[C], which copies a highlighted sequence to the
clipboard. To distinguish between keystrokes that represent a note and
keystrokes that represent a macro, a momentary foot pedal is used as a mode switch.

Layout
KEYed User Interface setup
Design
The design of the layout incorporates the four sequencer windows most commonly
used by the composer. The functions associated with each window map to a specific
octave on the piano controller keyboard. For example, the transport octave is used
to play, stop, record, mute, and solo a sequence or a specific MIDI channel.
Please refer to the "Keyboard Mappings" section for details of the mappings.
For continuous parameters, we have integrated a single point touchpad. The touchpad
is used for constrained vertical or horizontal actions, for a single degree of freedom
task like sliding a fader, and to perform a full two degree of freedom task
like drawing a modulation graph, as shown in the below figure.

System Requirements
The following are the hardware and software requirements to run the KEYed user interface prototype:
-
Platforms Supported: Win2K, Win98
- Steinberg Nuendo 1.5 for Windows
- Any MIDI compatible piano keyboard
- Cirque Glidepoint touch pad (serial port)
- MIDI In/Out of the piano keyboard connected to a SB PC128 soundcard
- MIDI thru of the piano keyboard connected to a SB Live! soundcard
- A momentary foot pedal plugged into the foot switch port of the piano keyboard
- Libraries MIDIIO32.ocx and LMNK.dll (Download from the "Software" section)
- KEYed.exe file (Download from the "Software" section)
