From the perspectives of art-making and aesthetic enjoyment, technology could play a transformative role in penetrating the transitional frameworks of conventional art forms and unfolding the possibilities of innovative approaches for community, social, and cultural engagement.

Mobile App i-Orchestra

i-Orchestra is an iOS app developed by Lee Cheng that enables orchestral simulation in a mobile device ensemble setting. Each ensemble player can simulate an orchestral part via compatible MIDI controller connected to an iPhone / iPad, which collaboratively forms a keyboard orchestra. It enables keyboard players to develop ensemble skills within a virtual environment.

Compared to the ordinary setting of keyboard ensemble using digital musical keyboards with built-in synthesizers, i-Orchestra offers benefits including mobility, specific orchestral samplers, smaller size and an opportunity for students to learn manipulating mobile music technology. i-Orchestra could be useful in setting up mobile device ensembles in school setting. Further development of the software would increase the affordance of the app for wider music-making possibilities not limited to MIDI keyboards.

i-Orchestra 是一個為iPhone 及iPad所開發的流動應用程式,用作建立模擬管弦樂團的流動裝置樂隊。 每位樂手可以透過 i-Orchestra 及 MIDI 鍵盤模擬指定的管弦樂器演奏,再組合成一隊模擬管弦樂團,並從中學習合奏技巧。

相比於一般使用電子琴模擬管弦樂的樂隊,i-Orchestra 具有更佳的流動性,以及提供學習運用流動音樂科技的機會,適合於學校環境中讓學生於參與樂團演奏的同時學習更多音樂及科技知識。
