I missed the deadline for the ’29 Bagpipes’ competition, but here’s what I produced from those 51.1 seconds of audio: 4 pairs of looped stereo samples, one octave apart, from A#2 to A#5. Each pair contains a ‘harmonics’ part (‘harm’), which contains the harmonic content from the processed 51.1 seconds, plus an ‘inharmonic’ part (‘inharm’), which contains all the non-harmonic content from the processed 51.1 seconds. All the parts can be enveloped, filtered and pitch-shifted – in particular, the inharmonic part can be shifted by non-musical intervals, and does not need to track the played pitch, so key tracking need not be 100%. The video shows four example sounds that have been synthesized using the pairs, using an Instrument Rack inside Ableton Live, but similar results can be obtained by using other sample player applications like Contact et al. I am sure that the Pianobook community will synthesize more sounds!
