In a household type sewing machine having a bed, a standard rising from said bed, a horizontal arm overhanging said bed, said arm ending with a head, a needle bar means disposed in said head for enabling transverse oscillation thereof relative to the direction of fabric feed in said sewing machine, feed means for adjusting the length and direction of said fabric feed, and actuator means for adjusting the transverse position of said needle bar means and the positional displacement of said feed means in response to control signals provided thereto; the improvement comprising static memory means for retrievably storing stitch pattern data capable of providing a plurality of different composite stitch pattern arrangements having associated bight and feed data corresponding to stitch positional coordinates of said needle bar and feed means; microcomputer integrated circuit means operatively connected to said static memory means and to said actuator means for selectively processing said stored stitch pattern data from said static memory means and providing output control signals to said actuator means based on said selectively processed stitch pattern data capable of selectably controllably adjusting the transverse position of said needle bar means and the positional displacement of said feed means, said microcomputer processing means comprising means capable of selectively controllably functionally operating on said stored stitch pattern data in response to input control signals for selectively creating output control signals for said actuator means capable of defining a selected composite stitch pattern arrangement; and keyboard means operatively connected to said microcomputer means for providing said input control signals to said microcomputer processing means for initiating the selection of said stored stitch pattern data and the functional operation to be performed on said selected stored stitch pattern data for selectably controllably adjusting the transverse position of said needle bar means and the positional displacement of said feed means for selectively providing said selected composite stitch pattern arrangement from said stored stitch pattern data, said keyboard means comprising a first common key selector having a plurality of modes for initiating selection of at least any one of a plurality of said stored stitch patterns in a first mode and for varying the positional coordinate data associated with said one selected stored stitch pattern in a second mode for providing said input control signals for enabling said selecting and redefining of said stored stitch pattern for providing said different stitch pattern arrangement whereby said sewing machine is capable of providing stitch pattern arrangements corresponding to said stored stitch patterns per se as well as to selectably creatable variations thereof.
