Pianoboi is a web app that visually displays sheet music in real-time as you play a MIDI keyboard. It aims to help musicians learn pieces more easily by providing instant feedback and a clear visualization of the notes being played. The application supports multiple instruments and transpositions, offering a dynamic and interactive way to practice and explore music.
YouTube Sequencer turns any YouTube video into a customizable drum machine. By mapping different sounds to sections of the video's timeline, users can create unique beats and rhythms simply by playing the video. The platform offers control over playback speed, individual sound volumes, and allows users to share their creations with others via unique URLs. Essentially, it transforms YouTube's vast library of video content into a massive, collaborative sample source for making music.
Hacker News users generally expressed interest in YouTube Sequencer, praising its clever use of YouTube as a sound source. Some highlighted the potential copyright implications of using copyrighted material, especially regarding monetization. Others discussed technical aspects like the browser's role in timing accuracy and the limitations of using pre-existing YouTube content versus a dedicated sample library. Several commenters suggested improvements, such as adding swing, different time signatures, and the ability to use private YouTube playlists for sound sources. The overall sentiment was positive, with many impressed by the creativity and technical execution of the project.
Music Generation AI models are rapidly evolving, offering diverse approaches to creating novel musical pieces. These range from symbolic methods, like MuseNet and Music Transformer, which manipulate musical notes directly, to audio-based models like Jukebox and WaveNet, which generate raw audio waveforms. Some models, such as Mubert, focus on specific genres or moods, while others offer more general capabilities. The choice of model depends on the desired level of control, the specific use case (e.g., composing vs. accompanying), and the desired output format (MIDI, audio, etc.). The field continues to progress, with ongoing research addressing limitations like long-term coherence and stylistic consistency.
Hacker News users discussed the potential and limitations of current music AI models. Some expressed excitement about the progress, particularly in generating short musical pieces or assisting with composition. However, many remained skeptical about AI's ability to create truly original and emotionally resonant music, citing concerns about derivative outputs and the lack of human artistic intent. Several commenters highlighted the importance of human-AI collaboration, suggesting that these tools are best used as aids for musicians rather than replacements. The ethical implications of copyright and the potential for job displacement in the music industry were also touched upon. Several users pointed out the current limitations in generating longer, coherent pieces and maintaining a consistent musical style throughout a composition.
