by Teletext QuartetComposed by: Lennon & McCartneyThe Teletext Quartet arose out of an initial meeting between the boys when all my AMPLINEX pieces were put on to a single disc.
They quickly realised that they each wanted to be more than a visual by-line in someone else's music, and settled down to some serious practice. Before long they had chosen a mutual favourite, Lennon and McCartney's song 'Yesterday', as their first performance piece. They now present this to an audience for the very first time - and are hoping that they'll soon get the hang of the lyrics. Singers... how they work The coordination of music and display is achieved, as you may have guessed, by using ACT. This allows the part being played to tailor the display. Two ACT words are used. 'staccact' is early in the action sequence and divides each note into 7/8 length note and 1/8 length rest. This is set at position 10, early in the action sequence. The main work is then done by 'singact', which picks up each note action from position 20, and then adjusts the mouth shape to fit the type of action. There are two shapes, 'o' for a note and '=' for a rest. The words to display these ('ee' and 'oh') use 'place' to put them in the right position, depending on the player number that calls them. The other words that might be of interest are 'no(show)_cursor' which access the video chip registers to hide or display the cursor, and there's also 'put' which uses VDU 31 to place the text cursor at a given position (row col put) and 'wait' which just IDLEs until the action queue is empty. The music parts are completely normal and the technique could be used with any four parts without change. So perhaps the lads can sing your tunes too? Richard |
