It's essentially just a way of creating a curved path from one point to another.\u003c\/p\u003e\n\u003cp\u003eIn this module, you have up to sixteen user configurable points or nodes which function much like a step sequencer, where the X axis represents time and the Y axis represents voltage.\u003c\/p\u003e\n\u003cp\u003eWhen the phase(time) reaches the X position of a node, the 1v\/oct output changes to the Y position value of that node.\u003c\/p\u003e\n\u003cp\u003eEach of the sixteen nodes also has a configurable trigger setting, determining if the gate output goes high when the phase crosses the X position of the node.\u003c\/p\u003e\n\u003cp\u003eThe nodes are connected by a spline and the shape of this spline is determined by three parameters; Tension, Continuity and Bias. The spline output gives you a voltage following this curve.\u003c\/p\u003e\n\u003cp\u003eTension changes how extreme the curve between the nodes is.\u003c\/p\u003e\n\u003cp\u003eContinuity sets the angle of the spline at the node.\u003c\/p\u003e\n\u003cp\u003eBias shifts the Tension to the left or the right of the node.\u003c\/p\u003e\n\u003cp\u003eYou can adjust what part of the full spline will be output by changing the Zoom and Scroll parameters.\u003c\/p\u003e\n\u003cp\u003eThe curve loops at the end, so when zoomed all the way out, the last node connects to the first.\u003c\/p\u003e\n\u003cp\u003eThe speed at which the phase progresses through the nodes can either be set using the \"frequency\" parameter fluidly, or quantized to fixed frequencies listed in .scl files in the \"scales\" directory on the module. The cycle frequencies range from 16 minutes per phase to 20kHz, so very slow LFO rates all the way up to the limits of hearing.\u003c\/p\u003e\n\u003cp\u003eThe output amplitude can be changed using the level parameter and CV input. This allows the module to be used without a dedicated VCA.\u003c\/p\u003e\n\u003cp\u003eWhen the spline shape goes higher or lower than the +-5v limits, a few different clipping options are provided, such as wavefolding or soft clipping. Since all parameters can be overdriven substantially, this makes for some interesting effects.\u003c\/p\u003e\n\u003cp\u003eThe sync input is also configurable, letting you manage timing like you would a tap tempo lfo, an envelope generator or a step sequencer for instance.\u003c\/p\u003e\n\u003cp\u003eFor working with control voltages, a basic rolling oscilloscope is available for each of the six CV inputs, including scaling and offset settings so you can adapt the control voltage signal visually, directly in the module.\u003c\/p\u003e\n\u003cp\u003eDeveloper resources such as drivers, templates, pin configs and best practices are also provided, in case you would like to use the module as a development platform for your own ESP-32 based DSP projects.\u003c\/p\u003e\n\u003cp\u003eThe firmware and quantizer scales can be updated easily by drag and drop via the front accessible USB C port.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cdl\u003e\n\u003cdt\u003eDimensions\u003c\/dt\u003e\n\u003cdd\u003e10 HP\u003c\/dd\u003e\n\u003cdd\u003e31 mm deep\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdl\u003e\n\u003cdt\u003eCurrent Draw\u003c\/dt\u003e\n\u003cdd\u003e50 mA +12V\u003c\/dd\u003e\n\u003cdd\u003e50 mA -12V\u003c\/dd\u003e\n\u003cdd\u003e170 mA 5V\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003ciframe width=\"1336\" height=\"752\" src=\"https:\/\/www.youtube.com\/embed\/3HHW01QuNY0\" title=\"introducing splines\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"THORN.AUDIO","offers":[{"title":"Black","offer_id":47537465163949,"sku":null,"price":413.0,"currency_code":"USD","in_stock":true},{"title":"Silver","offer_id":47537465196717,"sku":null,"price":413.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/3449\/7197\/files\/Untitleddesign_1fee61fb-d6ec-4f61-8cc9-25f84a63cb66.png?v=1789160063","url":"https:\/\/www.detroitmodular.com\/products\/thorn-audio-splines","provider":"Detroit Modular","version":"1.0","type":"link"}
