OSD is centered around combining voltage in useful ways. Audio, V\/Oct, and control voltage are at home in this utility. OSD offers a fully DC-coupled signal path with precision components to make this happen. High quality, configurability, and compact size ensure OSD will always find its way into your patch.\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eCombine v\/Oct sequences with precision summing, or enable the precision OR circuit for completely different results\u003c\/li\u003e\r\n\u003cli\u003eMix two envelopes or an envelope and LFO using sum to create large accented voltages or combine with OR to keep the output in the original range\u003c\/li\u003e\r\n\u003cli\u003eCrossfade between audio or control voltage using the potentiometer in block one, setting DIF will invert the signal at the B jack\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch3 id=\"toc_0\"\u003eWhat is OR, SUM, and DIF?\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eOR - Input voltages are compared and the higher of the two is passed to the output (if A = 4V and B = 8V, the output will be 8V)\u003c\/li\u003e\r\n\u003cli\u003eSUM - Input voltages are added together to create the output voltage (if A= 3V and B=4V, the output will be 7V, this clips at -10V and 10V)\u003c\/li\u003e\r\n\u003cli\u003eDIF - Lower voltage source is subtracted from the higher voltage, producing an output of the difference between the two (if A= 3V and B = 5V, the output will be 2V)\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch3 id=\"toc_1\"\u003eControls\/Configuration\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eBlock 1 - Sum, OR, or Difference of two inputs and effect the mix of the A input to the B input with the Knob, the third input ORs with the result of the A\/B inputs\u003c\/li\u003e\r\n\u003cli\u003eBlock 2 - Sum, OR, or Difference two inputs with a fixed mix of 50%, the third input ORs with the result of the A\/B inputs\u003c\/li\u003e\r\n\u003cli\u003eBlock 3 - 3 input OR, mix gates or CV from three sources for some wild results\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"WMD","offers":[{"title":"Default Title","offer_id":44450693415015,"sku":"155931","price":189.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/wmd-osd_155931_1_d3c1d7c4-2a58-45ec-b6d9-b0cfa48c6bda.jpg?v=1787094129","url":"https:\/\/vintageking.mom\/products\/wmd-osd-or-sum-dif","provider":"Vintage King","version":"1.0","type":"link"}
