Study on the construction of operational models for a remote performance system

远程演奏系统是通过传输线将放置在不同地点的乐器（MIDI兼容）连接起来，使这些乐器能够实时同时统一演奏的系统。本研究的目的是考虑远程性能系统的操作模型，并测试和检查这些模型的一部分。这项研究使用了最新的能够转发MIDI数据的系统“iSession”（雅马哈），并通过光纤将位于不同地点的仪器连接起来。此外，还采用了一个电话会议系统，从表演地点进行视频和音频通信。提出了以下三个模型作为使用这些系统的操作模型。一是针对个人的“远程个课模式”，二是针对多名学生的“远程音乐课程模式”，三是针对多名表演者和观众的“远程独奏模式”。针对这些模型的操作状态、操作内容和使用的仪器，考虑了具体的计划。在雅马哈音乐基金会的合作下，信州大学（长野）教育系与该基金会（神奈川）建立了联系，并进行了试验。“远程音乐课程模式”使用安装了最先进的自动演奏系统并连接到远程爵士钢琴课程的三角钢琴来实现。此外，使用电动鼓组，在日本进行了第一次远程鼓课程。“远程独奏模型”调查了在远程位置与表演者进行会话的可能性。通过这些试验，在对学生和参与者进行问卷调查的基础上，调查了远程绩效系统运行模式的教育效果等。此外，还澄清了在执行这些试验期间发现的今后任务的必要性。

A remote performance system is a system which connects by a transmission line instruments (MIDI compatible) placed at different points and enables the simultaneous and unified performance of such instruments in real time. The purpose of this study is to consider operational models for a remote performance system and test and inspect a portion of such models.This study used "iSession" (Yamaha), the newest system able to forward MIDI data, and connected instruments located in different spots via fiber optics. Furthermore, a teleconference system was also employed to communicate video and audio from the performance spots. The following three models were proposed as operational models using these systems. First is the "Remote Individual Lesson Model" targeting the individual, second is the "Remote Music Course Model" targeting multiple students, and third is the "Remote Recital Model" targeting multiple performers and audience members. Specific plans were considered for the operation state, operation content, and instruments used for these models.With the cooperation of the Yamaha Music Foundation, the Education Department of Shinshu University (Nagano) was connected with the Foundation (Kanagawa) and the trials were conducted. The "Remote Music Course Model" was implemented using a grand piano installed with a state of the art automatic performance system and connected to a remote jazz piano course. Also, using an electric drum set, the first remote drum course in Japan was conducted. The "Remote Recital Model" investigated the possibility of a session conducted with a performer in a remote location. Through these trials, the educational effect, etc., of operational models for a remote performance system was investigated based on a questionnaire survey given to students and participants. Also, the necessity for future tasks, discovered during the execution of these trials, was clarified.
