{"product_id":"mutable-instruments-streams","title":"Mutable Instruments Streams","description":"\u003cp\u003eThe \u003cstrong\u003eMutable Instruments Streams\u003c\/strong\u003e provides two channels of extremely flexible signal dynamics manipulation.\u003c\/p\u003e  \u003cp\u003eEach channel consists of an analog voltage-controlled filter and amplifier (VCFA). The response curve of the amplifier section is continuously variable from exponential to linear. The amplifier gain is directly controllable from a CV input, through an attenuator. But what makes Streams truly unique is the multi-purpose EXCITE input. The signal routed to this input is analyzed by a micro-controller and translated into internal control voltages for the VCFA, turning Streams into a very versatile signal contouring tool:\u003c\/p\u003e  \u003ch3\u003eEnvelope generator\u003c\/h3\u003e  \u003cp\u003eThe EXCITE input can work as a trigger input, triggering an internal AD or AR envelope routed to the gain and the filter cutoff (in variable amount). With only 6-HP of space, you can shape an oscillator or noise source into a full-bodied sound.\u003c\/p\u003e  \u003ch3\u003eVactrol curve generator\u003c\/h3\u003e  \u003cp\u003eThe EXCITE input is processed by a digital model of a resistive opto-isolator (Vactrol), controlling the gain and the filter cutoff (in variable amount). The digital emulation allows the modification of properties of opto-isolators – such as response time – which are otherwise difficult to control. The virtual vactrol response can be either optimized for processing CVs, or triggers (for “plucked” sounds).\u003c\/p\u003e  \u003ch3\u003eAmplitude and frequency content follower\u003c\/h3\u003e  \u003cp\u003eThe envelope and cutoff of the EXCITE signal is measured, and applied to the signal on the VCFA input.\u003c\/p\u003e  \u003ch3\u003eCompressor\/limiter\u003c\/h3\u003e  \u003cp\u003eStreams’ VCF is disabled, and the VCA is used to control the dynamics of the input signal. An intuitive control scheme allows the compressor to be used either for peak reduction\/limiting operation; or for boosting signal levels with soft-limiting. The EXCITE input can be used as a sidechain.\u003c\/p\u003e  \u003ch3\u003eDigital control modes\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eAD or AR envelope generator.\u003c\/li\u003e \u003cli\u003eVactrol response generator – gated or pinged\/struck.\u003c\/li\u003e \u003cli\u003eAmplitude and cutoff follower.\u003c\/li\u003e \u003cli\u003eCompressor.\u003c\/li\u003e \u003c\/ul\u003e   \u003ch3\u003eI\/O (per channel)\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eMulti-purpose EXCITE input.\u003c\/li\u003e \u003cli\u003eDC-coupled Audio\/CV input (normalized to +5V constant voltage).\u003c\/li\u003e \u003cli\u003eVCA gain CV (normalized to +8V constant voltage).\u003c\/li\u003e \u003cli\u003eOutput.\u003c\/li\u003e \u003c\/ul\u003e   \u003ch3\u003eControls (per channel)\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eDigital control mode selection.\u003c\/li\u003e \u003cli\u003eResponse time \/ compression threshold.\u003c\/li\u003e \u003cli\u003eModulation amount \/ compression ratio and makeup gain.\u003c\/li\u003e \u003cli\u003eVCA gain CV input attenuator.\u003c\/li\u003e \u003cli\u003eVCA exponential to linear response curve.\u003c\/li\u003e \u003c\/ul\u003e   \u003ch3\u003eTechnical characteristics\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eAnalog signal path.\u003c\/li\u003e \u003cli\u003eAll inputs DC-coupled.\u003c\/li\u003e \u003cli\u003e12-bit, 31kHz EXCITE signal acquisition (for metering and following).\u003c\/li\u003e \u003cli\u003e16-bit, 31kHz control voltage generation.\u003c\/li\u003e \u003cli\u003eCortex-M3 ARM processor.\u003c\/li\u003e \u003cli\u003eOpen-source hardware and firmware.\u003c\/li\u003e \u003cli\u003e12-HP.\u003c\/li\u003e \u003cli\u003eEasy firmware updates through an audio interface.\u003c\/li\u003e \u003cli\u003eCurrent consumption: +12V: 100mA ; -12V: 30mA.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Mutable Instruments","offers":[{"title":"Default Title","offer_id":47248087548041,"sku":"57014","price":259.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/8706\/5737\/files\/mutable-instruments-streams_57014_1_823e738b-f551-4d9d-8343-68d0e030bc23.jpg?v=1784046731","url":"https:\/\/vintage-king-staging.myshopify.com\/products\/mutable-instruments-streams","provider":"Vintage King Staging","version":"1.0","type":"link"}
