Overview
At Humelo (휴멜로), led the development of AI systems for music composition, lyrics generation, and rap synthesis. This project combined deep learning with music theory to create AI-aided music, culminating in collaborations with major K-pop artists, presentation at SXSW 2019, and a feature in a KBS Documentary with professional rapper Sleepy.
Key Achievements
- SXSW 2019: Presented AI-aided music production at South by Southwest in Austin, Texas
- SM Entertainment Collaboration: Worked with SM Entertainment through KOCCA’s “Music X A.I.” program
- KBS Documentary Feature: Featured on KBS1 Documentary “New-contents, changing the world” with professional rapper Sleepy
- Media Coverage: Covered by 10+ national media outlets
- Artist Collaborations: Created AI-generated music with Korean hip-hop band XXX, rapper Sleepy, and other artists
- Patents: Multiple registered patents for polyphonic music generation systems
Technical Approach
ALPHACH - LSTM-based Chord Progression Melody Composing
Developed an AI system (ALPHACH) for music composition using LSTM-based models capable of:
- Generating chord progressions based on music theory constraints
- Creating melodic compositions over generated chord sequences
- Polyphonic music generation using LSTM and polynomial approaches
Lyrics Generation and Rap Synthesis
Created a system for automated lyrics generation and rap synthesis that:
- Generates contextually coherent rap lyrics
- Synthesizes rap vocals for collaboration with human artists
- Featured in the collaboration with professional rapper Sleepy on KBS Documentary
AI-Aided Music Production (SXSW 2019)
SXSW 2019 Showcase: “XXX - Flight Attendant”
- Integrated sound and visual interpretation
- Collaborated with XXX (Korean Hip-hop Band), Seonggu de Kim (Sound Designer, DJ), and Seong Pil Kim (Visual Artist)
Tech Stack
- Deep Learning: Seq2Seq, LSTM, Polynomial models for music generation
- NLP: Lyrics generation, text processing
- Audio: Sound synthesis and rap vocal generation
- Framework: TensorFlow

Period
2017 - 2019
Impact
This work demonstrated that AI could be a creative partner in artistic endeavors, opening new possibilities for human-AI collaboration in music and entertainment. The extensive media coverage across 10+ national outlets and the KBS Documentary feature brought significant public attention to AI-generated music.
