  • Judging Comments
    Overall, many of the contest entries utilized the Vocal Synthesis function to substitute vocals by simply playing the song melody in Note Mode, and in some cases, it was possible to find more suitable, alternative tones. However, achieving the desired phrasing was difficult without utilizing the CT-S1000V's Phrase Mode for this project, which fully demonstrates the instrument’s capabilities.

    Additionally, when lyrics are played in Note Mode, the pitch attack tends to be delayed due to pronounced consonant phonation. This issue was compensated for by using the Phrase Mode. At the same time, if the pitch and the lyrics attack are too closely aligned, the sound can become mechanical. This was avoided in this entry by expressing natural nuances through subtle deviations in timing.

    The idea of combining Death Voice with beatboxing is also really interesting, and the unique atmosphere created in combination with the machine-like glitchy electronica beats and human-like chorus phrases fits perfectly with the concept of the CT-S1000V as a new musical instrument, rather than just another sound source. Although not a direct evaluation criterion, the fact that all audio used to create the music is sourced from the CT-S1000V is a fantastic demonstration of the instrument's potential.
