{"product_id":"thorn-audio-splines-vector-curve-generator-black","title":"thorn.audio - Splines Vector Curve Generator [Black]","description":"\u003cp\u003eSplines is a visual vector curve generator with a wide frequency range, a built-in quantiser, CV scope and CV processing capability. It can be used in a similar way to a wavetable VCO, LFO, step sequencer or envelope generator and features a built-in quantiser. Settings can easily be saved, and the firmware updated, via USB. It’s a small, shallow, multifaceted addition to any setup and, for touring rigs, it can fulfil many roles while taking up minimal space and weight.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"Apple-converted-space\"\u003eFeatures:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSplines are curved paths used in 3D modelling and animation. This module uses them as a 16-point sequencer where X = time and Y = voltage.\u003c\/p\u003e\n\u003cp\u003eEach point triggers changes to the 1V\/oct output when the phase (time) crosses it, with an optional gate trigger per point. The points are connected by a spline shaped by three parameters: Tension (curve intensity), Continuity (angle at each point), and Bias (shifts tension left or right).\u003c\/p\u003e\n\u003cp\u003eZoom and Scroll control which portion of the spline is output. Frequency sets the phase speed — from 16-minute LFO cycles up to 20kHz — and can be quantized using .scl scale files.\u003c\/p\u003e\n\u003cp\u003eLevel controls output amplitude, replacing the need for a dedicated VCA. When the signal exceeds ±5V, clipping options like wavefolding and soft clipping add further sound-shaping potential.\u003c\/p\u003e\n\u003cp\u003eA rolling oscilloscope is built in for all six CV inputs, with scaling and offset controls.\u003c\/p\u003e\n\u003cp\u003eThe sync input is configurable for tap tempo, envelope, or sequencer-style timing.\u003c\/p\u003e\n\u003cp\u003eA hardware expander — adding physical knobs for Tension, Continuity, Bias and Level, plus CV inputs for Scroll and Zoom — is due summer 2026.\u003c\/p\u003e\n\u003cp\u003eFirmware and scales update via drag-and-drop over USB-C.
