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. |
