With an <strong>envelope follower circuit<\/strong> we can achieve a direct control of the amplitude of the signal.<br \/>\nIt will produce a control voltage proportional to the amplitude. Allowing a real communication between our system and the external sound source.<\/p>\n<p><strong>Instrument interface<\/strong> module has the following blocks:<\/p>\n<p><strong>\u201cPREAMP\u201d<\/strong><br \/>\nWith two audio inputs (6.5 jack and Minijack), input amplification is controlled with \u201cGAIN\u201d pot, controlling the amplitude of the envelopes that will be generated.<br \/>\nMinimum signal required to generate the maximum envelope is 200mV peak and allows up to 5v input.<\/p>\n<p><strong>\u201cBPF\u201d<\/strong><br \/>\nThe signal will pass through a band pass filter with cutoff frequency and band width control via \u201cFREQ\u201d and \u201cWIDTH\u201d pots.<br \/>\nLike this we will select the frequency range that will generate our control signal.<br \/>\nAfter this stage the signal will be outputed with synth level via \u201cAUDIO OUT\u201d.<\/p>\n<p><strong>\u201cENV.FOLLOWER\u201d<\/strong><br \/>\nAfter filtering the signal it will feed \u201cRESPONSE\u201d stage, that will determine envelope follower response velocity. It features a \u201cHIGH\u201d, \u201cMEDIUM\u201d and \u201clOW\u201d selector switch to get an optimal envelope for different kind of signals. \u201cFOLLO OUT\u201d will output the envelope extracted and show us it\u2019s level via a LED. Green: Medium level, Orange: High level and Red: Max. Level.<\/p>\n<p><strong>\u201cENV.REGENERATOR\u201d<\/strong><br \/>\n\u201cREGE OUT\u201d is a re-generated envelope that will allow controlling the rise of the envelope with \u201cATTACK\u201d and the fall with \u201cDECAY\u201d, making them longer or shorter.<br \/>\nIt features a LED indicator for the regenerated envelope level. Green: Medium level, Orange: High level, Red: Max. Level.<\/p>\n<p><strong>\u201cTRIG.EXTRACTOR\u201d<\/strong><br \/>\nWith \u201cTHRESHOLD\u201d pot we control the level of a comparator that determines when \u201cGATE OUT\u201d and \u201cTRIGG OUT outputs will be activated.<br \/>\n\u201cGATE OUT\u201d will be at high level while the envelope is over the threshold we set, while TRIGG OUT is present just when the threshold is passed.<br \/>\nIndication LEDS will show when the outputs are active.<\/p>\n","protected":false},"featured_media":10530,"comment_status":"open","ping_status":"closed","template":"","meta":{"_mi_skip_tracking":false},"product_cat":[150,122,76],"product_tag":[224],"_links":{"self":[{"href":"https:\/\/technosynth.com\/en\/wp-json\/wp\/v2\/product\/7305"}],"collection":[{"href":"https:\/\/technosynth.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/technosynth.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/technosynth.com\/en\/wp-json\/wp\/v2\/comments?post=7305"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/technosynth.com\/en\/wp-json\/wp\/v2\/media\/10530"}],"wp:attachment":[{"href":"https:\/\/technosynth.com\/en\/wp-json\/wp\/v2\/media?parent=7305"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/technosynth.com\/en\/wp-json\/wp\/v2\/product_cat?post=7305"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/technosynth.com\/en\/wp-json\/wp\/v2\/product_tag?post=7305"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
