DEATH INTERNETZ Guitar Synth by Cat Full of GHOSTS!!!

DEATH INTERNETZ Guitar Synth by Cat Full of GHOSTS!!! from Cat Full of GHOSTS on Vimeo.

"a prototype for seb, hoping to kick-starter it later this year.

Turns your smooth guitar waves into harsh square waves!!!!

Its a heavily modded PWM circuit based on a schematic from the great Tim Escobedo
But its got :
Pulse width Modulation
Power starve of the hex inverter, for dirt and malfunction or pulled all the way down its a nice overdrive distortion.
waveshaper, almost sounds like a filter
lfo!!! (sqr type) driving PWM
Volume (it goes from silent, to very very loud!!!)
and sense threshold, for added noise on guitar pickups.

In this example i'm just running a sin-wave in."

Video Equations: Colour Video Synthesizer

Video Equations: Colour Video Synthesizer from Cat Full of GHOSTS on Vimeo.

The Video Equations video synthesizer is currently seeking funding on Kickstarter here. This is a project by Cat Full of GHOSTS' Roberto Jordan, who I am happy to say, happens to be a supporting Member of MATRIXSYNTH. See the kickstarter campaign for additional details including the different reward levels.

"The Video Equations system utilises the power of mathematics to yield rippling lo-fi seas of colour, acid trip roguelikes, glitching fractals, visions of an 80's techno dream and worlds of crashing computer programs, all from a single, beautiful unit.

Equally at home in the studio, lab or on the road this colour video system is ready for take off!"

Some additional details via the Kickstarter campaign here

"Features:

16 colours, hundreds of characters and symbols
20+ different equation archetypes each with two modifier sliders and a colour depth control for literally millions of unique stable or evolving visuals
colour and character offset knobs for even more control and variation of output
4+ variable size masks, each with an invert function and mask fill options
9v battery or wall wart operation (wall wart not included)
7 X 0-5v CV inputs for modular control of all sliders and knobs
picture mute and equation hold functions for expanded live use
composite NTSC output (PAL users can buy a NTSC to PAL converter to integrate it into their PAL system. There is a cheap one for sale here.) The jack on the synth is BNC but comes with an RCA adapter.
Kit and build options:
Available as a fully built and tested unit or as a DIY kit with all the components (all thru-hole components). Both kit and built unit come with a rugged acrylic and plywood base."

"Its a one of a kind PAL, composite video synth, that is small, awesome looking and runs of 5-9v DC

It makes a but tone of crazy strobing, morphing and glitching B&W video.
it may look crazy but it has hyper stable sync output meaning you can run it into a projector or video mixer with no fear of signal loss or instability.
Controls include (from left to right):
stability (how quick the frame refreshes, this creates strobes, static images, and slow morphing opacity effects, range: 0ms to 4ms)
clear type (how the frame refreshes: none, black out, white out, invert rand, invert always)
direction (direction to offset the image: up, down, left, right, diagonal 1, diagonal 2, diagonal 3, diagonal 4, glitch apart 1, glitch apart 2, random)
offset (the distance the screen image is offset)
shape type (the shape being generated then effected by the synth: none/black, circle, square, tri, tri2, lines, dots, lots of circles, 80's logo thing)
output: RCA composite video
input: DC power 5-9v (wall wort not included)

Anyway here is a video!!!!!!"

Cat Full of Ghosts YOWLER Kickstarter Campaign Opens Design to Supporters

YOWLER KICKSTARTER VIDEO from Cat Full of GHOSTS on Vimeo.

"The Kickstarter video for a synthesizer that the buyers help design.

www.kickstarter.com/projects/218568730/the-yowler-a-community-built-diy-noise-synth"

"About this project

Low epic throbbing halls, rasping vocal choruses, burning thick churning waves of static. The Yowler is waiting.

The Yowler is a versatile little noise/drone synth, don't let it's size fool you, it is packed with features most small synths don't have:

External trigger + decay: trigger the Yowler from external gear, use it as a drum synth

Built in speaker + mono/stereo output: means you can use it with mono gear like guitar pedals or a modular synth, or stereo gear like mixers, headphones etc...

Pitch knobs + light dependent pitch control: get crazy sounds from the three oscillators by shining light on them

BUT WAIT THERE IS SO MUCH MORE...

If the minimum successful funding amount is raised, you get the Yowler as you see it in the video, with all the features described. BUT, once we reach the funding goal backers will be able to contribute to the design and development of the final product. How? Read on.

WHAT'S A COMMUNITY BUILT SYNTH?

Ever $1,000AU above the fully funded amount unlocks a bunch new options for features that the backers get to vote on having included in the final design. Some of these upgrades are aesthetic, like better knobs and buttons, others are extra features like a filter or the design becoming open-source, or Eurorack compatibility, and others are design improvements, like a case, a thicker PCB, or rubber feet.

The idea is that as a community the backers will steer and shape they Yowler through their choices. The more people who support the Yowler the better it gets.

When each voting milestone ($1,000AU over the funding goal) is reached, I will send out a survey to backers to decide between two new features. If enough voting milestones are passed then features are passed over will return for a second chance of inclusion. If your favourite feature missed out early on, with enough backers, it may still end up in the final product!

New tbar Eurorack Module from Cat Full of GHOSTS

Published on May 2, 2017

"The tbar is a unique unipolar/bipolar variable voltage source and attenuator made by Cat Full of Ghosts Electronics. It boasts beautiful white and gold pcb front panel, walnut stained bamboo ply and matte black bolts. The tbar also boasts a visual feedback led under the + sign so you can monitor the cv you are passing in attenuator mode.

This module will make you feel like you are flying a space ship. It has a smooth motion a firm throttle and solid construction.

The tbar allows for more nuanced control of cv parameters. Why twiddle a cramped knob when you can slide a tbar? It is great for performance and studio use.

The output can be configured to: 0-5v, -5-5v, 0-9v or -5-9v via jumpers on the underside.

This unit is 6hp wide and 51mm deep. It draws current relative to what it is driving but you can expect around 40-50ma on the +12 and -12 rails.

Cat Full of Ghosts Hell Synth: DIY Digital Noise Terror on Kickstarter

On Kickstarter here. Follow-up to this post.

"The 'Hell Synth' is a palm sized experimental synth you can buy prebuilt or as a kit. Little noise synths are often limited in the scope of their sound, either they grind aggressively like dive-bombing aeroplanes, or drone in massive arrays of humming square-waves.

THIS HELL SYNTH IS A LITTLE DIFFERENT! The range of sounds that come out of this little box will keep you twiddling for hours. There are oceans of glass, lightening fast arpeggios, swarming notes that dance in and out of phase.

This is the fifth version of this synth design and the tenth version of the software. Ive been working to make sure it is fun to use while being full of awesome sounds.

So far there are two programs I have written for it including:

FROM HELL!!! :
This is a hard-core noise synth with six digital wavetable oscillators, tons of glitch, modulation and waveforms. It also has midi out.

ARP BOX1:
A cute little arpeggiator with both audio and MIDI out, capable of everything from Casio-style acid crazy to bleepy-bloops."
