After a quick and error free load, the menu is presented on the screen. By immediately opting for the play command the program proceeds to play 51 bars of Mozart's "Eine Kleine Nachtmusik" - very impressive indeed. There are also two other pieces of music on the cassette and these can be loaded in at any time.
The main use of 'Composer' however is to help you to compose your own music. A maximum of 80 bars can be typed in and the music can then be altered, if necessary, by deleting, inserting and copying new bars. A graphic display of each bar is available and after every bar is written the computer will play it so that you can check to see if it is right. One, two or three of the channels can also be changed within any given bar. Yet another feature enables you to change the speed, sound, key and name of the music. Obviously all music can be saved and reloaded at will.
Composer has to be one of the best utility cassettes currently available for the Oric-1 48K and certainly provides value for money.
