The EAMIR padKontrol system uses the Korg padKontrol USB MIDI controller and PC or Mac compatible software to compose music. When the software is launched, the user can select between two modes of operation: Absolute Mode and Relative Mode. Both modes utilize the padKontrol’s 16 touch-sensitive pads to create chords in some manner.
This project was developed by V.J. Manzo, PhD and is available here. More information on EAMIR is available here.
Hardware:
- Korg padKontrol by Korg®
Software:
-Download padKontrol Software here
Modes:
The software can route the MIDI data to an external synthesizer, but it also implements General MIDI to achieve internal synthesis. The two knobs on the controller set the MIDI program values for both the XY pad and the 16 pads. These program changes will ultimately change the synthesis timbres.
By clicking on the inversion buttons on the right, the user can have the pad generated chords played in different inversions.
To record a performance as a standard MIDI file, click the button marked “Record”. To stop the recording, press “Stop Record”. You will then be prompted to save the file to a location on your computer. The MIDI file will have the 16 pads on Channel 1, and the X/Y pads on Channel 2. The file can then be brought into any program that works with MIDI such as Pro Tools, Logic, and Garage Band, as well as notation programs like Finale and Sibelius.
Relative Mode operates similarly to Absolute Mode, but In Relative Mode, the user selects a tonic and a mode before playing. The user may choose from a list of 12 pitch classes and the 28 diatonic modes of the major scale, the harmonic minor scale, the melodic minor scale, and the harmonic major scale (major scale b6). By default, the key of C Major is selected. Each of the 4 pads in the first two rows is voiced according to the chords that naturally occur in our tertian system of harmony. When pressed, the first pad of the first row will yield a C Major chord, the 1 chord in the key of C Major; the second pad of the first row will yield a d minor chord, the 2 chord in the key of C major. If a different tonality is selected, different tertian chords will be built. When a pad is pressed and a chord is played, the software determines the chord function and quality as it relates to the selected mode and tonic, and looks for the chords that normally follow the selected function. When these are found, the lights beneath these pads will begin to blink. If a user pressed the 2 chord in C Major, pad 5 begins to blink and he can easily see that the 2 chord normally resolves to the 5 chords. If the 5 chord is pressed, the chords that normally follow the 5 chord will begin to blink. This blinking does not cause any change in sound, but provides the user with suggestions for their performance with regard to the function of chords in functional Western harmony. Each of the 4 pads in the last two rows creates a secondary dominant (V/V, V/ii, etc.) for each of the chords created by pressing pads 1 – 8 (first two rows). The user can change this secondary dominant chord to a secondary leading tone chord, a minor subdominant or other borrowed chords that tonicize the 7 diatonic chords.
