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 Taof making an inquiry about a present time Tb of the counterpart device and a time Taof receiving a response from the counterpart device while setting a time Tawhich progresses from the time Taand a time interval Td which is counted from the time Ta. 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+(Ta−Ta)−(Ta−Ta)/2, or Td+Tb+(Ta−Ta)+(Ta−Ta)/2.
