Perhaps its most obvious function is that of a sixteen band graphic equalizer. The sixteen bands are labeled in hex (0 through F) at the top and bottom of the module and the center frequency of each band is indicated above each slider attenuator.\u003cbr\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eATTENUATOR OUTPUTS\u003cbr\u003eThe signal input jacks, in the center beneath the sliders, offer the choice of putting a signal in to the eight even numbered bands, all sixteen bands, or the eight odd bands. (Note that these are just the even or odd numbered bands on the equalizer and have no correspondence to even or odd harmonics.) The ATTENUATOR OUTPUTS at the top of the module also offer \"even\", \"odd\", or \"all\" signal outputs. With a signal patched into the \"ALL\" signal input and taken out through the \"All\" attenuator output the module functions just as a sixteen band graphic equalizer. Note on the scale for the attenuators that 0 dB is just below the top range of the sliders and that a slider at the very top is actually giving a 6 dB boost to frequencies in that band. An attenuator at the very bottom will completely cut off any signal in that frequency band. The signal output jacks directly above each attenuator offer the signal present within that frequency band. These outputs are not affected by the attenuator's positions. The COMB FILTER outputs offer the\u003cbr\u003esignals from either all the \"even\" or all of the \"odd\" bands and are also unaffected by the attenuators.\u003c\/li\u003e\n\u003cli\u003eCONTROL VOLTAGE OUTPUTS\u003cbr\u003eThe control voltage outputs labeled ENVELOPE OUTPUTS are envelope follower outputs for each frequency band. In other words, the voltage from these outputs represents the amplitude of the signal present within each band. The switch in the upper left-hand corner selects \"long\" or \"short\" envelope decay times. These outputs are not affected by the positions of the attenuators.\u003c\/li\u003e\n\u003cli\u003ePROGRAMMED OUTPUTS\u003cbr\u003eThe SPECTRAL PROCESSOR can be voltage controlled in a variety of ways. The results of any control voltage manipulation are presented to the PROGRAMMED signal outputs. It is possible to \"sweep\" through the various frequency bands much (much like a bandpass filter can \"sweep\" the frequency spectrum) using the pot on the far left· of the PROGRAM CONTROL section. This pot can be voltage controlled through the control voltage input labeled FREQ. The small knob beside the input is an inverting attenuator the same as others on the synthesizer. On the right is a WIDTH control pot which determines the widths of the sixteen frequency bands. The labeling above each attenuator indicates the\u003cbr\u003eapproximate center frequency of each band. Notice that as the bandwidth gets very narrow \"gaps\" appear: between each band and then the bands disappear completely and no signal is passed. At The MAX setting each band is so wide as to encompass the entire frequency spectrum and the FREQ control will have no effect. This pot can be voltage controlled but it has no attenuator on the control voltage. The LOCAL PROGRAM INPUTS allow individual voltage control of the signal level in each frequency band. With no control voltage the signal for that band is cut off. As a control voltage increases the signal is gradually unattenuated.\u003c\/li\u003e\n\u003cli\u003eSPECTRAL BIAS\u003cbr\u003eThe pair of knobs and switches labeled SPECTRAL BIAS have a function often associated with a \"vocoder\" circuit. Unfortunately the labeling on these controls has no relationship to their function and should be ignored. (They were originally intended for a different purpose). The left switch, when up, patches each \"even\" envelope follower output into its neighboring \"odd\" control voltage input. In effect this causes the SPECTRAL PROCESSOR to analyze the signal present at the \"even\" input and to duplicate its frequency spectrum in the \"odd\" bands. If the signal presented to the \"odd\" input has a broad enough frequency spectrum itself the \"odd\" PROGRAMMED OUTPUTS will match timbres with the \"even\" signal. The right switch performs the same function going from \"odd\" to \"even\". (NOTE: Despite the fact that this is a three position switch, only the top and bottom positions have any function.) If a microphone signal is the signal being analyzed, a harmonically rich signal from an oscillator can be made to duplicate vowel sounds in speech. (This is known as a \"vocoder\" patch.) For this to work best the input signal requires special equalization. This is the purpose of the two knobs. When turned to the right they boost the treble range of the \"even\" and \"odd\" input signals respectively. Since they affect both the ATTENUATOR and PROGRAMMED outputs they should be turned down (to the left) unless setting up a \"vocoder\" patch. Be aware that the BANDWIDTH and FREQUENCY controls are still in effect when using these switches.

A potentiometer is used to set a temperature reference voltage. This reference voltage is compared with the voltage from a chip-temperature sensor transistor. The resulting difference voltage is then applied to a chip heater transistor via an error amplifier.

It includes an electronically separate pulse generator with voltage controlled period and pulse length (duty cycle). \u003c\/p\u003e\n\u003cp\u003eThe Model 245 produces up to 5 programmed voltages at each of four outputs. \u003c\/p\u003e\n\u003cp\u003eThe Sequencer employs three methods of selecting stages; pulse advancing, analogue selection, and pulse selection. All can be used simultaneously or in any desired combination. \u003c\/p\u003e\n\u003cp\u003ePulse advancing is used for generating sequences of control voltages. A pulse derived from the self contained pulser or from an external source advances the sequencer one step. sequencers may be cyclic over a number of stages or may be single shot, beginning and ending on any desired stage. Sequence boundaries are established by switches located between stages. \u003c\/p\u003e\n\u003cp\u003eAn analogue select input permits the value of an applied control voltage to determine the activated stage. Higher voltages select higher numbered stages; zero volts enables the pulse advance and pulse select inputs. Analog selection is particularly useful for converting a continuous voltage (from an envelope Generator or detector or a random voltage source) into a series of pre-selected values (a 12 tone scale for example). It also enables indirect addressing by another sequencer and facilitates simple (one patchcord) extension of the Model 217 Keyboard's number of programmable outputs to 5.\u003c\/p\u003e\n\u003cp\u003eThe sequencer may be employed as a preset controller (a random access memory), with pre selected parameter values recalled by applying a pulse to the input of the desired stage. This pulse selection, used in conjunction with pulse advancing, allows several transient or cyclic sequences (different rhythms, for example) to be simultaneously programmed. A desired program might be initiated by pulses from a keyboard or another sequencer. \u003c\/p\u003e\n\u003cp\u003eLight emitters and pulse outputs are energized as corresponding stages are actuated. The period of the self contained, voltage controlled pulser has a range of .005 to 10 seconds. Pulse width can be varied from 1% to 100% of the period.\u003c\/p\u003e","brand":"ELECTRIC MUSIC STORE","offers":[{"title":"Default Title","offer_id":48955695333528,"sku":null,"price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/9729\/files\/245_Panel.jpg?v=1777854508"},{"product_id":"buchla-m-e-m-s-dual-control-voltage-adder-model-256","title":"Buchla \u0026 M.E.M.S.

They are useful for \"remembering\" the instantaneous value of a control voltage (a detected envelope, for example), for generating equally spaced steps from a constant slope input (as from a 280 envelope generator), and for converting any continuously changing voltage (a random voltage, for instance) into a series of discrete values.\u003c\/div\u003e\n\u003cdiv class=\"v1gmail-n6owBd v1gmail-awi2gc\" style=\"font-size: 16px; color: rgb(0,0,0); font-family: 'Google Sans','Helvetica Neue',sans-serif; margin: 12px 0px 16px; border-bottom-width: 0px; border-bottom-style: none; border-bottom-color: rgb(10,10,10);\"\u003eThe 264's sample-and-hold circuits have two operating modes: sample and track. In the sample mode, the value of the input is sampled and applied to the output whenever a pulse is received. The output remains at this value until the next pulse arrives. The track 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 the pulse and remains at a constant value until the next pulse.\u003c\/div\u003e\n\u003cdiv class=\"v1gmail-n6owBd v1gmail-awi2gc\" style=\"font-size: 16px; color: rgb(0,0,0); font-family: 'Google Sans','Helvetica Neue',sans-serif; margin: 12px 0px 16px; border-bottom-width: 0px; border-bottom-style: none; border-bottom-color: rgb(10,10,10);\"\u003eThe Model 264 includes a polyphonic adapter, which performs the logic necessary to implement four-voice polyphony.
