For some of the results I scaled note velocities down to get softer sounds from the virtual instruments, and sometimes edited one or two notes. Finally, I created a simple percussion track by using the default transcription and mapped it to a percussive virtual instrument… so all the drum strokes you hear are linked to guitar note onsets. I added pads by setting the parameters to get fewer long notes and then a simple electric guitar and toy piano by keeping the highest notes from the transcription and shifting them up. 24.5.3 Non-Western Music Most AMT methods aim specifically at modelling Western tonal music, but there is much less work done on automatically transcribing. I first created a synth by running the transcription with default values, and then a bass by keeping only the lower notes and shifting them down one octave. I then added a simple drum line using a chiptune-style drum VST, and finished it off by time-aligning and pitch-correcting some notes that were too out of line.”īy Juan José Bosch (Research Scientist, Spotify): “How far could I go using only a single instrument recording and Basic Pitch? I tried to find out with a guitar recording from a song I made playing arpeggios, and ran it through Basic Pitch with different parameters to generate different musical elements in MIDI format. The lower pitches were set to be a bit more in the background in terms of volume but also timbre, while the higher pitches contained the main melody and was given that typical, piercing chiptune style. I split all detected notes into high- and low-pitch and applied the Icecream VST to each, to generate a chiptune-like sound. in-key, in-rhythm), which by accident added its own flair to the resulting music. For this song, Basic Pitch managed to detect many notes correctly, and the estimation errors it did make where musically still sensible (i.e. Due to the repetitive nature of the piece, I decided to only focus on the initial few sections. 11 in A major by Mozart (also called “Alla Turca”). By Daniel Stoller (Research Scientist, Spotify): “I started from Paul Werner’s comical interpretation of the well-known Sonata No.
