  • the control system connects hardware transducers such as amplifiers, synthesizers and multitrack recorders to a programmable computer.
  • the connection as such to a fader 15 console is optional and not strictly necessary.
  • Inputs from the hardware transducers are representative of their working status, for example, the voltage levels of voltage controlled amplifiers as stated above.
  • the inputs are monitored, by the computer of the ⁇ . control system scanning the inputs at a rate substantially faster than any change in hardware status whilst allowing for the storage of the hardware statuses.
  • i i Conversion of the inputs into digital form is preferably via a bus structure.
  • ?1 - Storage of the input information is preferably in the memory of the computer on conventional floppy disc.
  • the time reference means is preferably a clock oscillation generated and controlled by the computer, synchronizing the position of a manipulation of sound within , 0 the overall musical piece.
  • the input identifying means comprises information preferably associated with a sequence of inputs, to identify those inputs as forming a particular passage or mix within a musical piece. Identification can preferably also include .,,. information on the musician or vocalist, the instrument( s) and any other indicia that assist in identifying the particular passage or track over earlier mix attempts.
  • the visual display ; means is preferably a screen, said screen displaying input information preferably by graphical and/or colour means such that, when applicable, the maximum possible manipulation is also indicated.
  • the screen display is preferably designed to display the input information in conjunction with input identifying means, as described above, so that the user of the system has visually before him all the information required to adequately

  • These command functions enable easy operation of the control system assisted by a help function and menu displays which direct the user,when the need arises.
  • a sequence of sounds, such as music, j is recorded with respect to a time code. Any changes to the sound made by the sound engineer is inputted into the control system against a time code reference being either real time or time with respect to the musical piece as a whole by storing the degree of change as a digital quantity against the time reference. This can be referred to as a first mix.
  • Playback of the sound will include the changes made *by the sound engineer as the processor monitors the information in its storage and repeats the changes occurring at each time point. j •
  • the- system provides 'the advantage of playback of the new mix without the need for any further recording of the sound on tape until the mix has been finished to the satisfaction of the sound e ' ngineer.
  • This first mix can be referred to as a mix file and subsequent manipulators will generate a new mix file as changes made by the sound engineer are stored. Old mix files are not discarded unless specifically ,deleted and pecific sounds such as solo pieces or specific time intervals of music can be manipulated and entered into the mix (ie. a master mix file) as required.
  • Each mix file can be given a title and the title stored on a menu for recall purposes. Updating the mix can be effected by executing commands such as (PLAY) (JOIN) (MIX) A (FROM) (time) (EXECUTE), or for example, (GO TO) (JOIN) (MIX) (AT) (CUE) (titTe such as solo) (EXECUTE).
