Latest Patents

Murata's latest patents include a storage medium, tone generation assigning apparatus, and tone generation assigning method. This invention allows a generator to determine a chord based on one or more notes from depressed keys in a chord key area. When the harmony function is activated, it automatically generates additional notes that harmonize with the pitch of the depressed key. These notes are then inputted into an assignment controller, which assigns various timbres to the notes and sounds them accordingly. This process enhances the tone generation assignment, not only for user-performed notes but also for automatically generated additional notes.

Another significant patent focuses on automated performance technology using audio waveform data. This invention enables playback of waveform data at variable performance tempos while maintaining sound quality. It performs timeline-expansion and contraction control on the waveform data based on the relationship between the performance tempo and a desired reference tempo. The technology can limit playback to prevent system freezes and ensure high-quality sound, addressing issues such as slower tempos or sound interruptions.
