{"product_id":"tip-top-buchla-200-series-264t-quad-sample-and-hold","title":"Tip Top Buchla 200 series 264t Quad sample and hold","description":"Four independent sample-and-hold circuits, plus a specialized logic circuit for expediently implementing polyphonic patches.\nSample-and-hold’s are essentially one-cell analog memories. They are useful for “remembering” the instantaneous value of a\ncontrol voltage (a detected envelope, for example), for generating equally spaced steps from a constant slope input (as from a 281t\nenvelope generator), and for converting any continuously changing voltage (a random voltage, for instance) into a series of discrete\nvalues.\nThe 264’s sample-and-hold circuits have two operating modes: sample and track. In the sample mode, the value of the input is\nsampled and applied to the output whenever a pulse is received. The output remains at this value until the next pulse arrives. The\ntrack mode differs in that an input is applied to the output for the duration of the pulse. The output tracks the input until the end of\nthe pulse and remains at a constant value until the next pulse.\nTo use the 264t as four independent channels set the separate\/common switch to separate. A single CV can be set to all four\nchannels by setting the operate\/common to common and plug CV in the the back jack on the with right side.\nThe Model 264t includes a polyphonic adaptor, which performs the logic necessary to implement four-voice polyphony. Facilities\nare incorporated for fine tuning and f.m. modulating the oscillators; light emitters display the adaptor’s operation.","brand":"Photosynthesis","offers":[{"title":"Default Title","offer_id":47205003690171,"sku":null,"price":279.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2986\/3355\/files\/TiptopBuchla264tQuadSampleandHoldPolyphonicAdapter.jpg?v=1765473878","url":"https:\/\/www.photosynthesisolympia.com\/products\/tip-top-buchla-200-series-264t-quad-sample-and-hold","provider":"Photosynthesis","version":"1.0","type":"link"}
