Creating Music with Code

Play Songs with Konduktiva
In Konduktiva, users are allowed to input chord progressions using Roman numerals and melodies using relative semitone. This makes it possible to recreate existing songs using Konduktiva.
Konduktiva utilizes a system called Quantized maps. A Quantized map is like a scheduler for events or information, so that the right note can be played at the right time. This system is used to manipulate things such as chord types (chord map), root note (root map), MIDI velocity (velocity map) etc.
Users can use this block of code to input the chord progression of John Coltrane's Giant Steps into Konduktiva:
addChordProgressionFromRomanNumeral(e, "giantSteps", 64, [0, 2, 4, 6, 8, 12, 14, 16, 18, 20, 22, 24, 28, 30, 32, 36, 38, 40, 44, 46, 48, 52, 54, 56, 60, 62], ["Imaj7", "bIII7", "bVImaj7", "bI7", "IIImaj7", "bVII7", "bIII7", "bVImaj7", "bI7", "IIImaj7", "V7", "Imaj7", "bV7", "bI7", "IIIma7", "bVII7", "bIII7", "bVImaj7", "IIm7", "V7", "Imaj7", "bV7", "bI7", "IIImaj7", "IIm7", "V7"], "B")

Because Konduktiva uses MIDI signal to communicate with MIDI instruments, users can also capture the output via a digital audio workstation (DAW):
