Abstract: A system for automatically generating an accompaniment note pattern and a bass pattern programmed therein by the player. The system includes a programmable microprocessor wherein two patterns, one sounding in the frequency range of the solo and accompaniment manuals and the other in the frequency range of the pedals, can be programmed into a programmable and reprogrammable memory by the player by means of a separate keypad or one or two octaves of keys on the regular keyboards. The patterns are programmed in without regard to key, and on playback, the microprocessor is responsive to the chord being played at that time on the accompaniment manual to transpose the read out patterns to a compatible key. Means are provided for phase locking simultaneously occurring notes of the two patterns if they are of the same or octavely related frequencies. This is accomplished by causing both notes to be taken off the same divider string if a match of pitch occurs.

Abstract: A selectable rate sync generator system for use with a television test pattern generator includes a master oscillator of predetermined frequency, selector switches for selecting the desired total horizontal line time, and a horizontal line trigger circuit for generating a train of clock pulses having twice the repetition rate (2H) of the line time selected. H rate blanking and drive pulses are generated in response to the clock pulses. Selector switches are provided for selecting a desired number of horizontal scanning lines in two fields, and a vertical trigger circuit generates vertical trigger pulses having the repetition rate (V) of the number of lines selected. V rate blanking and drive pulses are generated in a response to the V trigger pulses, and the H and V rate blanking pulses are summed to provide a composite blanking signal. H rate sync pulses are generated in a response to the clock pulses and are delayed therefrom by a predetermined interval.

Abstract: The application relates to an interlace detector for a raster beam control circuit, such as in a television or computer display. Under 1:1 interlace conditions, depending on the condition of the logic at the time that the 1:1 interlace is selected, an odd field condition may result wherein the first half of the top horizontal line and the second half of the bottom horizontal line are blanked. The interlace detector detects this situation by detecting coincidence between a horizontal blanking pulse and the vertical reset pulse, and delays the transmission of the vertical reset pulse to the vertical field counter for one-half of the horizontal line scan time. This, in turn, delays vertical blanking so that a full line of information appears in the upper and lower lines of the display. In the specific embodiment disclosed, a bistable circuit triggered by horizontal blanking pulses and the undelayed vertical reset pulse produces the delayed vertical reset pulse.
