This instrument play intervals. The tilting of the laptop controls the intensity of each note (tilting front or back play the root note and tilting to the sides play the "interval" note). The sound is played trough a LeSLOrklie speaker (it rotates around the Hemi at an adjustable spin frequency).

Description

The program senses mouse movement, and plays chords (each note of the chord on a different channel) at the volume which cooresponds to the speed of the mouse movement. It can be modified to play through a Hemi or through laptop speakers.

Usage

Installation

Executing

  • Using a terminal go to the folder where "koolkeys.ck" is located
  • On the terminal window type: (replace N with the number of output channels of the audio card) 
    chuck -cN koolkeys.ck
  • Play!

Playing

This program works much like a keyboard on a piano, and is highly based off of the virtual keyboard in Garage Band.

  1. Select the root note by using 2nd and 3rd rows of the keyboard (from A & W to P & '). See root note selection for details
  2. Play chord by moving finger over trackpad
  3. Optional:

Key mapping

Root note selection

Register selection

[+] to Increase by 1 octave ([=] will suffice).
[-] to Decrease by 1 octave.

Ping tempo

[ [ ] to decrease ping tempo by 5 bpm.
[ ] ] to increase ping tempo by 5 bpm.

Chord isolation

[SHIFT] + [1] to select lowest note
[SHIFT] + [2] to select medium low note
[SHIFT] + [3] to select medium high note
[SHIFT] + [4] to select highest note
[SHIFT] + [5] to select all of chord.
