In this blog post, we introduce MIDI-DDSP, which leverages the expressive power of DDSP to create realistic-sounding audio, but also enables editing from slower input data like MIDI. While it’s fun to manipulate individual amplitudes and frequencies, these features are very low-level (250 times a second), so we wanted a way to also play DDSP models with more familiar note-level controls like MIDI. Recently, we proposed DDSP, which combines DSP and neural networks to generate realistic audio with interpretable controls. On the other hand, samplers and black-box neural audio synthesis (e.g., WaveNet) can sound more realistic but offer less individual control. While synthesizers can produce many sounds for each note, it is difficult to find control settings to produce realistic-sounding audio. It allows us to use notes and control signals to play synthesizers and samplers, for instance sending “note-on” and “note-off” information when pressing a key of a MIDI piano keyboard. MIDI is a widely used digital music standard for creating music in live performances or recordings. ![]() We are pleased to introduce MIDI-DDSP, an audio generation model that generates audio in a 3-level hierarchy (Notes, Performance, Synthesis) with detailed control at each level. ![]()
