  • Patent number: 11734344
    Abstract: An acoustic parameter editing method is used in a plurality of terminals configured to receive editing of an acoustic parameter and a management apparatus individually connected to the plurality of terminals and including a preview memory configured to preview the acoustic parameter before reflecting the acoustic parameter in a sound signal processing engine. When a first terminal among the plurality of terminals is connected to the management apparatus and a request for the preview is made from the first terminal, the management apparatus causes the first terminal to refer to the preview memory in response to the request from the first terminal. Thereafter, when a second terminal among the plurality of terminals is connected to the management apparatus and a request for the preview is made from the second terminal, the management apparatus causes the second terminal to share the preview memory referenced by the first terminal.

  • Publication number: 20220172745
    Abstract: An acoustic parameter editing method is used in a management apparatus and a terminal. The management apparatus includes a first parameter memory configured to indicate an acoustic parameter and is connected to a sound signal processing engine configured to perform a sound signal processing by reflecting the acoustic parameter. The terminal includes a second parameter memory having the same memory structure as that of the first parameter memory in at least apart thereof. The management apparatus receives the acoustic parameter to update the first parameter memory. The terminal receives the acoustic parameter to update the second parameter memory when not connected to the management apparatus, and to update the first parameter memory when connected to the management apparatus. When the first parameter memory is updated, the terminal updates the second parameter memory in synchronization with the updated first parameter memory.

  • Patent number: 9305531
    Abstract: An online real-time session is conducted between at least two electronic music devices each equipped with an interface and a touch panel display for displaying a plurality of performance operators. The same displayed content is shared in real time between electronic music devices by mutually transmitting operation information representing a user's operation on a performance operator, so that the operational state of the performance operator of one electronic music device is reflected in the counterpart electronic music device. A setting operator is used to select a desired music section corresponding to one layer or a combination of layers subjected to simultaneous music performance. The electronic music device generates sound in response to a short press given to a performance operator, while the electronic music device sets a tone-generation point to a performance operator pertaining to a long press.

  • Publication number: 20150186108
    Abstract: When an audio data is received from the input/output device (I/O), the received audio data is transmitted to a first PC (first processing engine) and a second PC (second processing engine) in parallel. The first processing engine performs signal processing in the first PC, and the second processing engine performs signal processing in the second PC. They send back the processed audio data to a network SW. The network SW determines whether or not the audio data received from the first PC and the second PC is normal, and selectively transfers the audio data determined to be normal to the input/output device.

  • Patent number: 8461444
    Abstract: An online real-time session is conducted between at least two electronic music devices each equipped with an interface connectible to a communication network and a display with a touch sensing ability. An electronic music device communicates with its counterpart device to count a time Ta1 of making an inquiry about a present time Tb of the counterpart device and a time Ta2 of receiving a response from the counterpart device while setting a time Ta3 which progresses from the time Ta2 and a time interval Td which is counted from the time Ta3. Thus, the electronic music device determines tone-generation timing at which the electronic music device is synchronized with its counterpart device in conducting an online real-time session by way of a calculation of Td+Tb+(Ta3?Ta1)?(Ta2?Ta1)/2, or Td+Tb+(Ta3?Ta2)+(Ta2?Ta1)/2.

  • Patent number: 8175731
    Abstract: A digital mixer has a custom component specified by a configuration ID. Further, the same configuration ID is provided to another custom component for ensuring compatibility of scene data which is used for operating the custom component. When a custom component of the mixer configuration is edited, the edited custom component is provided with the same configuration ID as the initial custom component before the editing. Scene data of the initial custom component can be copied to scene data of the edited custom component or vice versa provided that their configuration IDs match with each other.
