Harmonic Series Piano

Sunday, April 2nd, 2017

Raw harmonic series tuned piano

Here is how this piece was made. I played a 12 string electric guitar with a Wampler sustain pedal and Roland Space Echo pedal. Normalized, and reversed that track. Then I used Melodyne to extract a polyphonic midi representation – more or less that same as what the guitar sounded like. Then I added a midi echo effect that is called echo delay which also has a swing setting. The midi output of that was chained into Sonar’s track midi quantization and additional arpeggiator. This midi stream was then into to Kontakt with the tuning set to the harmonic series as show in the photo below.
