SLIDE 2 } Digital musical instrument
- interface: the 8 x 8 matrix of light emitting buttons.
- 64 buttons: may be activated in different ways to
generate musical tones and light.
} 3 music playing modes:
- Sweep mode, Memory mode, Gravity mode.
} 3 musical instrument voices:
- Guitar, Piano, Drum beats
} MIDI features
SLIDE 3
} 1. An ability to respond to user’s selection by producing
sound and emitting light when the buttons are pressed.
} 2. An ability to memorize the sequence, as well as play
the selected tones infinitely, in the order set by user.
} 3. An ability to utilize an accelerometer to detect the
inclination and direction of the device, so that the pitch and tempo of music can be changed.
} 4. An ability to load various musical instruments sounds
such as guitar, piano, and drum beats from the internal memory of the microcontroller and to play out sound.
} 5. An ability to control computers or other MIDI
instruments by sending MIDI, which are the operation data generated from the device, through the MIDI OUT interface.

SLIDE 5 } Sweep mode
- Music is played in a sequence such that when a
sweeping bar hits the buttons that were pressed, it generates the tones and light associated with the buttons.
- The vertical sweeping bar is virtual as it only serves
as a tool to count beats.
- It moves horizontally, one grid at a time, from left
to right and repeats.
- The eight columns represent the eight timing steps;
the eight rows represent eight different pitches.
} Memory mode
- Music is played and looped infinitely in a sequence
following the order the buttons were selected.
- 64 buttons represent 64 types of pitches.
SLIDE 6 } Gravity mode
- Accelerometer is used to detect device inclination.
- The selected button acts like a spherical object that
generates the associated musical notes and light based on its coordinates as it moves around the plane.
- The tempo of the playing tones is determined by the
device inclination.
SLIDE 7 } Fundamental criteria for analysis:
- Project’s major features
- Project’s PSSCs

SLIDE 8
- 1. Visually attractive interface:
- When a switch is pushed, the light is emitted and
user will have the points to generate the sound.
- Perform exactly the same function:
[PSSC1]: An ability to respond to user’s selection by producing sound and emitting light when the buttons are pressed.
SLIDE 9
- 2. Create Music with various kinds of loops:
- Score mode: When scan bar moves one by one from
left to right, it generates sound at the point where the switches were pushed and loops.
- Perform substantially the same function as the
Sweep mode. (Scan bar is not visible in Sweep mode.)
SLIDE 10
- Random loop mode: When switch is pushed one by one, the
point that was pushed should be memorized as the order it was pushed.
- Light moves between the points where switches were
pushed and the sound should be generated when the light hits the point.
- Perform substantially the same function as the Memory
- mode. (Light is only visible on the pressed buttons in Memory
mode.) [PSSC2]: An ability to memorize the sequence, as well as play the selected tones infinitely, in the order set by user.

SLIDE 12 } Performance Apparatus and Tone Generation Method
Abstract: “Plural key switches are arranged in two dimensions along X- and Y- coordinate axes, and an X- X-coordinate te positi tion of each of th the key switc tches is associated with to tone generati tion ti timing while a Y- Y-coordinate te positi tion of each
the key switc tches is associated with a to tone pitc
- tch. Storage section stores a
music piece data set that includes tone generating data having data ta of to tone pitc tches and to tone generati tion ti timing associate ted with th th the key switc
repeat-section setting mode, a repeat-section setting section causes the plural key switches to function as setting operators and sets ts a repeat t secti tion of th the music piece data ta set t on th the basis of th the X- X-coordinate te positi tion of any operate ted
