On the other hand, software sequencers were continuously utilized since the 1950s in the context of [[computer music]], including computer-''played'' music (software sequencer), computer-''composed'' music ([[algorithmic music|music synthesis]]), and computer ''sound generation'' ([[sound synthesis]]). In June 1951, the first computer music ''Colonel Bogey'' was played on [[CSIRAC]], Australia's first digital computer.<ref name=csirac>{{cite web

 }}</ref> In 1957 [[Max Mathews]] at [[Bell Labs]] wrote [[MUSIC-N|MUSIC]], the first widely used program for sound generation, and a 17-second composition was performed by the [[IBM 704]] computer. Subsequently, computer music <!-- and computer sound generation --> was mainly researched on the expensive [[mainframe computer]]s in computer centers, until the 1970s when [[minicomputer]]s and then [[microcomputer]]s became available in this field.

==== In Japan ====
In Japan, experiments in computer music date back to 1962, when [[Keio University]] professor Sekine and [[Toshiba]] engineer Hayashi experimented with the [[:jp:TOSBAC|TOSBAC]] computer. This resulted in a piece entitled ''TOSBAC Suite''.<ref name="shimazu104">{{cite journal |last1=Shimazu |first1=Takehito |title=The History of Electronic and Computer Music in Japan: Significant Composers and Their Works |journal=Leonardo Music Journal |date=1994 |volume=4 |pages=102–106 |doi=10.2307/1513190 |jstor=1513190 |s2cid=193084745 }}</ref>
