Island Logic is a new company associated with Island Records who have been developing software since the end of 1983 with their eye very much on the disc user market, and that means BBC owners. Their first product is The Music System, an advanced piece of software containing a Music Editor (based on System's program), a Synthesiser (Envelope Generator), a manuscript generator called The Printout and The Linker, which allows compositions to be strung together. All these are directed from a control screen employing icon graphics, Macintosh-style.

As well as the composition facilities, there is also a Keyboard option which allows the playing of notes from the keys. These are digitally recorded for playback if required. There is complete control of volume and a built-in metronome.

The most important part of the system remains the Editor with its use of all four voices, 15 available envelopers, automatic transposition, numeric or classic Italian tempo notation and automatic barline creation options. The Linker further increases the power of this Editor, which has always been the best available for a micro.

All the main programs come on a single floppy disc (although a two part cassette version is available). A second floppy disc supplies the song and sound library, backing tracks and pre-defined sounds. To bring it all under the user's control there is a 96 page user manual. Unfortunately, due to the necessity for last minute changes in the copy protection of The Music System, we were unable to give it anything but the briefest of trials here at A&B. However, we now have the full version and an exhaustive review will appear in the pages of the February magazine.
