defining module.\u003cbr\u003e\u003cbr\u003eFrom the original catalogue:\u003cbr\u003e\u003cem\u003eFor generating and modifying sound, the typical synthesizer patch is \u003c\/em\u003e\u003cem\u003eVCO-VCF-VCA, \u003cbr\u003elinked in series, with suitable control from keyboard, \u003c\/em\u003e\u003cem\u003esequencer or computer. \u003cbr\u003eThe VCO generates the raw sound, the VCF \u003c\/em\u003e\u003cem\u003edynamically varies the timbre (sound quality) \u003cbr\u003eand the VCA controls \u003c\/em\u003e\u003cem\u003ethe amplitude and produces the envelope on the sound event.\u003cbr\u003eThe \u003c\/em\u003e\u003cem\u003e\u003cstrong\u003eWAVE MULTIPLIERS (VCM)\u003c\/strong\u003e provides a new link in this chain, \u003c\/em\u003e\u003cem\u003erepresenting an \u003cbr\u003eadvance in synthesizer technology. \u003cbr\u003e\u003c\/em\u003e\u003cem\u003eThe Wave Multiplier could be placed j\u003c\/em\u003e\u003cem\u003eust before the VCF, like \u003c\/em\u003e\u003cem\u003ethat, the Wave Multiplier \u003cbr\u003eaffects the timbre, but unlike the VCF, whose \u003c\/em\u003e\u003cem\u003eaction is a subtractive process of filtering\u003cbr\u003efrequencies from the \u003c\/em\u003e\u003cem\u003einput waveform, the Wave Multipliers are able to dynamically process\u003cbr\u003e\u003c\/em\u003e\u003cem\u003ethe input waveform to produce new harmonically-related overtones.\u003cbr\u003e\u003c\/em\u003e\u003cem\u003eThis function should not be confused with ring modulation, since it is \u003c\/em\u003e\u003cem\u003ea non-linear process\u003cbr\u003eusing a single audio input. \u003cbr\u003eAlthough, it is \u003c\/em\u003e\u003cem\u003epossible to describe the effect of a VCF by saying the sound gets \u003c\/em\u003e\u003cem\u003e\"bass-heavy\",\u003cbr\u003emakes a \"wah-wah\" effect or sounds \"thin\", to describe \u003c\/em\u003e\u003cem\u003ethe sound of a Wave Multiplier is\u003cbr\u003emuch more difficult. \u003cbr\u003eThe input \u003c\/em\u003e\u003cem\u003esound comes out richer in harmonicas, somewhat similar to pulse-width\u003cbr\u003e\u003c\/em\u003e\u003cem\u003emodulation and to linear frequency modulation, but with a new \u003c\/em\u003e\u003cem\u003echaracteristic timbre.\u003cbr\u003eThe nearest we can come to describing the \u003c\/em\u003e\u003cem\u003eunique sound qualities (there are three different\u003cbr\u003esections) is to say \u003c\/em\u003e\u003cem\u003ethat they alter the timbre in exciting new ways, producing interesting\u003c\/em\u003e\u003cbr\u003e\u003cem\u003ealternative forms of signal processing which are unique in the Serge \u003c\/em\u003e\u003cem\u003eModular Music System.\u003cbr\u003e\u003c\/em\u003e\u003cem\u003eSince there are three entirely separate and different types of Wave \u003c\/em\u003e\u003cem\u003eMultipliers in this module,\u003cbr\u003ean enormously varied palette of new \u003c\/em\u003e\u003cem\u003eeffects can be synthesized.\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003eThe uppermost section is the simplest of the three multiplier s\u003c\/em\u003e\u003cem\u003eections, \u003cbr\u003ebut it has two switchable effects. \u003cbr\u003eWith the switch set at \u003c\/em\u003e\u003cem\u003ethe \"HI\" position, the module functions to \"square-up\" an \u003cbr\u003eincoming \u003c\/em\u003e\u003cem\u003esignal. \u003cbr\u003eThis is not the same as a simple comparator squaring \u003c\/em\u003e\u003cem\u003efunction, though, since there is a\u003cbr\u003erounded flattening of the signal \u003c\/em\u003e\u003cem\u003epeaks: an effect somewhat similar to overdriving a tube\u003cbr\u003eamplifier \u003c\/em\u003e\u003cem\u003e(except that in this version the process is voltage controllable!).\u003c\/em\u003e\u003cbr\u003e\u003cem\u003eWith the switch in the \"LO\" position, the module is a linear gain \u003c\/em\u003e\u003cem\u003econtrolled VCA. \u003cbr\u003eThis is useful for various functions such as amplitude \u003c\/em\u003e\u003cem\u003emodulation and for gating signals \u003cbr\u003einto the other sections.\u003cbr\u003e\u003c\/em\u003e\u003cbr\u003e\u003cem\u003eThe middle Wave Multiplier provides a sweep of the odd harmonics \u003c\/em\u003e\u003cem\u003e(1,3,5,7,9,11,and 13th)\u003cbr\u003ewhen a sine wave is applied to its input and \u003c\/em\u003e\u003cem\u003ethe knob is turned up or a control voltage is\u003cbr\u003eswept from low to high.\u003c\/em\u003e\u003cbr\u003e\u003cem\u003eThis effect is similar to overblowing a wind pipe closed at one end \u003c\/em\u003e\u003cem\u003eand thus the module can\u003cbr\u003ebe used to produce the sounds of various wind \u003c\/em\u003e\u003cem\u003einstruments. \u003cbr\u003eA second input is included to allow two signals to be \u003c\/em\u003e\u003cem\u003emixed before processing, \u003cbr\u003ea technique that we have found to be very \u003c\/em\u003e\u003cem\u003eusable. \u003cbr\u003eThis module can be used to explore timbral areas beyond the \u003c\/em\u003e\u003cem\u003erange of ring modulation, \u003cbr\u003ebecause there are more varied harmonics than \u003c\/em\u003e\u003cem\u003ethe sum and difference tones.\u003cbr\u003e\u003c\/em\u003e\u003cbr\u003e\u003cem\u003eThe bottom Wave Multiplier performs non-linear wavehaping known as \u003c\/em\u003e\u003cem\u003efull-wave\u003cbr\u003erectification, but with sophisticated level-compensating \u003c\/em\u003e\u003cem\u003econditioning as well. \u003cbr\u003eActually the circuit uses three full-wave \u003c\/em\u003e\u003cem\u003erectifier sections linked in a very refined \u003cbr\u003econtrollable format. \u003cbr\u003eEach \u003c\/em\u003e\u003cem\u003esection can double the frequency of a sine or triangle wave applied to \u003c\/em\u003e\u003cem\u003eits input. \u003cbr\u003eThus sweeping the VC input over its range will produce a \u003c\/em\u003e\u003cem\u003esmooth timbral transition \u003cbr\u003eusing the even harmonics (second, fourth \u003c\/em\u003e\u003cem\u003eand eighth). \u003cbr\u003eMany other partials are present in this basic sound, \u003c\/em\u003e\u003cem\u003ehowever, the sonorities are very rich \u003cbr\u003eand varied. \u003cbr\u003eA notable \u003c\/em\u003e\u003cem\u003efeature of this multiplier is that the full-wave rectification is not \u003c\/em\u003e\u003cem\u003eaccompanied \u003cbr\u003eby a reduction in the output amplitude. \u003cbr\u003eThere is no \u003c\/em\u003e\u003cem\u003ealteration of the essential level of the sound. \u003cbr\u003eThere are two inputs \u003c\/em\u003e\u003cem\u003eto provide mixing before processing and two outputs. \u003cbr\u003eOne output is a \u003c\/em\u003e\u003cem\u003e\"squared up\" version of the other. \u003cbr\u003eThis output resembles voltage \u003c\/em\u003e\u003cem\u003econtrolled pulse width modulation (only much more\u003cbr\u003e interesting).\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003cbr\u003eThe Wave Multipliers are among the most powerful timbral modifiers \u003c\/em\u003e\u003cem\u003eavailable on any\u003cbr\u003eanalog music synthesizer. \u003cbr\u003eThe rich varieties of \u003c\/em\u003e\u003cem\u003einter-patch possibilities are nearly inexhaustible and these\u003c\/em\u003e\u003cbr\u003e\u003cem\u003epossibilities combined with the flexibility of other Serge modules \u003c\/em\u003e\u003cem\u003ewill provide unique\u003cbr\u003esynthesis tools for the person who is eager to \u003c\/em\u003e\u003cem\u003eexperiment with entirely new classes of sounds.\u003cbr\u003eThe Wave Multipliers \u003c\/em\u003e\u003cem\u003eprovide what has too often been lacking in electric musics: \u003cbr\u003ea means of \u003c\/em\u003e\u003cem\u003egenerating sounds as complex and dynamically variable as those found\u003c\/em\u003e\u003cbr\u003e\u003cem\u003ein acoustic sound sources. \u003cbr\u003eYet these are also precision modules which \u003c\/em\u003e\u003cem\u003erespond accurately to control voltages, \u003cbr\u003eso they may be used to give \u003c\/em\u003e\u003cem\u003erepeatable results in the most exacting analog or digital\u003cbr\u003e\u003c\/em\u003e\u003cem\u003eapplications.\u003cbr\u003e\u003cbr\u003e\u003c\/em\u003ePCB:\u003cbr\u003e\u003cspan\u003e1.6 mm thick, double sided, green\u003cbr\u003ebase
