DU-NTSC is a modular visualizer, AV toy, and video generator
From hyper-nerdy label Detroit Underground comes a new tool that both visualizes signals and acts as a modular visual instrument – a new way of looking at what you’re doing in modular sound, and an object for visual creation.
Eurorack may be saturated with modules that do sound, but get ready for the next frontier: more visuals. Boutique label Detroit Underground has been a retro-futuristic hub for just those sorts of audiovisual fascinations. Label head Kero is an audiovisual artist himself, and has gravitated to music with visual elements – not to mention he’s put out a glitchy app and website and even started a series of album releases on VHS. (Yes, VHS. Full disclosure: I somehow wound up on this series; my VHS tape drops in September. I’m still shopping around flea markets for a deck before the tapes arrive.)
DU-NTSC is really two modules in one. It’s a visualizer/oscilloscope – so you can look at signal in your patches. And it’s a hackable, creative visual module, capable of outputting visuals and visual signals. (Not everyone is interested exclusively in their rack doing sound; some also want to stimulate sight.)
Highlights:
Input video – there’s a composite (analog, natch) video input
Input audio – it’s a one-channel oscilloscope with wide sample rate spectrum (228 Hz – 700KHz), just with unusually cool visualizations
Generate video patterns via multiple presets (or make your own with Arduino code!)
Control patterns with CV and gate control of visual parameters
Output video – video generator can be routed to composite, as can video signal and sync (with a hack) through Video Cinch feature
That patch-ability extends in all directions: you can use control voltage both to generate and control visuals, and gate keeps everything in time.
Full specs:
One channel AV Display for Eurorack Modular, PAL, NTSC Video Generator and One Channel Oscilloscope
CV Input controls Video Generator (Jack Mono 3.5)
Universal CV from modular, bipolar (+5/-5V) and unipolar (+5V)
Gate Input: resets the current pattern and turns the screen black when a positive signal is applied (Jack Mono 3.5)
Chaos Button: inverts on-screen colors in all patterns; use this button to decrease the sample rate on an Oscilloscope sub-program in order to display signals from a LFO
Video In: supports PAL/NTSC; it can connect with DVD, VCD, TFT Camera, Super Nintendo, VHS Tape, etc. via Cinch input
Composite Video Out: exports the video generator signal via the Cinch output
DU-NTSC is based on the Arduino Nano platform, allowing you to easily hack and create your own video patterns.
Over 16 video patterns (demo available)
One Channel Oscilloscope; with a sample rate from 700KHz to 228Hz
