Jones O'Tool Oscilloscope

Coming out in April 2012 is a new Euro-rack module that contains a color LCD oscilloscope and audio measurement tools.

Single & dual trace scope with internal & external trigger. DC to 20Khz. +/-10v DC, +/-5v DC, 0-10v DC and +/-10v AC coupled. Timebase adjustable from 100 uSec/div to 5 Sec/div. The slow timebases update the screen in real time, so you see the trace slowly sweeping across instead of waiting for it to sample the whole waveform and then refresh.

The inputs are "loop through" inputs. Meaning that they are like 2-jack multiples. So you can connect one module to the input and then run another cable to another module without needing multiples.

Besides the scope modes it also has several audio and CV tool modes:

- Levels - this is an LED-like display that shows "lights" for how long the waveform spends at each level. This allows you to see the upper and lower limits of the waveform, as well as distinguish between some types of waveforms by how the lights are shaded. For example a square wave just lights up the highest and lowest light corresponding to the top and bottom of the waveform, while a triangle is evenly lit, and a sine wave is lighter at the top and bottom and has a curved darkening of the lights towards the center.

- VU & Peak - Classic LED style VU and Peak meters. The VU displays in dbVU while the Peak displays in volts or dbU depending on the scale selected. Scales include 5v p-p, 10v p-p and +4dbU (you can input line level audio and see a calibrated display).

- Spectrum Analyzer - Adjustable levels and top frequency, as well as two types of display. Linear shows evenly spaced columns based on Hz, while the Log display a logarithmic spread of frequencies.

- X/Y display - Display Lissajous patterns. Has a voltage scale setting and a time averaging setting to sample the inputs over short or long periods of time to build up patterns.

Tentative specs are:

Width: 8HP
Depth 1.575" (40mm)
Current: 130ma of +12v, 10ma of -12v
Price: $250

New MVIP sample videos

I have created three new example videos using the MVIP to give people a better idea of the kinds of things it can be used for.

The first has an MVIP controlled with an AFG oscillator. A Z8000 sequencer changed the oscillator frequency, and also controlled a pair of A-110 oscillators plus a filter to make the sounds.

The second video has an MVIP controlled by an AFG oscillator. The oscillator goes through a VCA to show the MVIP settings with and without the oscillator. The sound is a ring mod of the AFG and another oscillator modulated by the same LFO as the VCA. The AFG is also modulated by an LFO to give it a waving motion.

The first half shows the oscillator in each of the CV inputs. The second half varies the frequency and uses a combination of brightness, bitswap, and mode CVs.

The third video is a quick test of doing some video feedback using the MVIP to process the signal from the camera to the monitor. The MVIP is a Euro video image processing module. No control voltages were used in making this video. Just manually turning the knobs on the MVIP while watching the monitor.

MVIP is Available

The MVIP (Mini Video Image Processor) Euro module is now available from Dave Jones Design.

Mini Video Image Processor

The MVIP is a Euro rack module, designed to fit into audio synthesizer racks made by Doepfer and other manufacturers. It is a stand alone video module, not part of the larger video synth system that I am still developing.

Specs:

Width: 14HP (2.8 inches)

Depth: 2.56 inches (6.5 cm)

Power: 140ma of +12 and -12 volts

Inputs: Composite video (NTSC or PAL), five control voltage inputs for +5 to -5 volts

Output: Composite video (NTSC or PAL) matches the format of the input, or jumper selected if no video input

Price: $595 plus shipping

Available: In Stock

MVIP Screen Captures

The YouTube video of the MVIP is fairly blurry so I am posting some screen captures from the original video so you can see the difference. The top one is the original, the lower one is a screen capture from YouTube.

MVIP Mini Video Image Processor

Coming in December 2010 from Dave Jones Design is the MVIP Mini Video Image Processor.

This Euro rack module is not part of the larger video synth system that I am designing for Euro rack. This is a stand alone video processing module. It mounts in a Euro rack and is compatible with Doepfer and other Euro audio modules. This module has a single composite video input and output. It works in NTSC or PAL, and auto-detects whichever you plug into it.

Unlike the larger video synth system that I am designing, this module does not require any other video modules to work. The larger video synth system will require video input, sync and output modules, plus whatever video processing modules that you want. The MVIP doesn't require any of those. It works by itself. On the other hand it also only processes a single video input and doesn't combine multiple video signals like the larger system.

You can see a very simple demo of the MVIP on YouTube: http://www.youtube.com/watch?v=xPXCnTyDXFA

(be aware that the YouTube video is very blurry compared to the original)

That demo doesn't use the control voltage inputs. It simply shows the changes made when turning the manual control knobs. I added titles to the video to show which knobs are being turned.

Full specs and prices will be posted by Thanksgiving, and modules will be available by Christmas.
