Ablation Test

Here we present the ablation test result to simulate the synthesis result if there is only DDSP synthesizer available, or there are only DDSP synthesizer and synthesizer parameters generator available.

The following samples labelled "DDSP-mean" are synthesized only using DDSP synthesizer, giving f0 contour directly transferred from MIDI sequence, and loudness sequence filled with the average note-on loudness of the instrument.

The following samples labelled "Note-mean" are synthesized using synthesizer parameters generator. The note expression controls are filled with average value of the instrument across training set.
