Interactive A/V Installation @ Phase Space NYC (5/6/2023)

in ,

Event link


I’ll have a some interactive pieces in place at this event coming up at Phase Space NYC.

‘Out of Phase’ is the last audiovisual show happening before the space transitions into something new as Andrei and Paloma depart for new adventures.

Expect CRT scopes and interactive projections to play with, alongside the multitude of talent on the poster.

I haven’t kept up with updates the past month or so due to a busy schedule, but have kept up the creative output amidst the client work. Still continuously working through a backlog of projects, music, and hope to find the time to share some of the recent events and visual projects I’ve been lucky enough to take part in.

I don’t know if anybody reads these things, but I hope you’re doing well!

Broken Alias performance at STILLSUITE A/V Showcase in Brooklyn

in , ,

Brief recap shots from a performance at STILLSUITE, an A/V showcase held at Millennium Film Workshop in Brooklyn.

I was asked to perform as part of the showcase and opted to focus on music this time around, and to give my chiptune focused project Broken Alias some attention, with Erin Wajufos (of Never Knows Better) providing some stellar accompanying visual projections. This 1 hour set was a sort of 'mobile music showcase' for me, utilizing unreleased material from 3 upcoming albums which were written and performed using LSDJ on the Nintendo Gameboy, the Dirtywave M8 portable tracker, and Caustic 3 - a DAW for mobile. I also decided to lug six of my CRT Scopes across town to display the music's waveforms (and, subsequently, think a lot about that exhausting choice).

Thanks so much to Erin and Anto who curated the showcase for having me, Erin for the custom live visuals, Dolphin Uppercut who shot and cut together this video (during the event!), and all those who had kind words or just stuck around 🕹🎵 Be sure to check out all the other talent that was a part of this fantastic live A/V showcase, as well as the host of the event, Millennium Film Workshop in Brooklyn!

Sync Eater: Retro Beige Edition

Video: Gleix Live @ NKB x Ars Electronica NYC // "60Hz" (Live AV performance)

in , ,

Performed live on September 9th, 2021 at Culture Lab LIC in NYC as part of a showcase put together by Never Knows Better at the Ars Electronica Festival Garden.

This performance utilizes a fully DIY modular audiovisual synthesizer, a collection of custom controllable systems built in Touchdesigner, and a CRT TV which has been modified into an pseudo-oscilloscope receiving dedicated audio & video feeds to generate colored waveforms.

Three 60Hz tones are generated by the AV modular representing the three RGB color channels, panned left, center, and right respectively. These three underlying tones, which the piece is fully built around, have harmonics which shift depending on the shape of the individual color channels in the image, with peaks of amplitude being built for each color's pixels as the image is scanned through on each refresh of the video signal. Additional waveform generators and simple oscillators are injected into the color channels and 'played' in tune with the underlying tones by dialing in exact frequencies, which at multiples of 60Hz, will also form stable scanlines in the receiving color channel.

Touchdesigner serves as a complex collection of controllable systems for handling & manipulating audio, video input, as a standalone visual system, to introduce generative elements and contained-randomness when triggering external audio elements and visual subsystems, and for general data & MIDI processing. Percussive elements, rhodes, and additional audio processing in FL Studio.

A fully revised video synth is here! Model no. GVS010 - 'Vimana' (videos, photos, info)

in ,

GVS010 (link)

‘Vimana’

It’s been a bit of a journey getting here - but for the time being I’m finished with revisions.

This device is model no. GVS010 and is the first in the series to feature a fully revised internal design & silkscreen printed front panels. All additional circuits have been consolidated into a single PCB (excluding the additional patch-panel PCB up top), and all controls are now PCB mounted as well. This is, moving forward, the standard build style that the GVS series will take as far as the feature selection on the front panel goes.

Check out the page linked above for more information, a full demo video, an additional demo utilizing GVS010 as a loopback with a video mixer, and more photos than were really necessary :P

If you’re on the waiting list I’ll be reaching out soon - thank you for patience. Things may be a bit slower moving forward as my pre-pandemic work location has reopened, but I still plan to work through commissions for those who have made requests.

Development update on the Sync Eater

in ,

Just a little progress update on where things are at with the Sync Eater -

These are some photos of my personal pre-production builds using what I believe will be the final panels & PCBs. I made one in black, one in white, and experimented a little bit with some blue on black. Going by public opinion I’ll most likely offer this device in all black but may do a limited run in all white and some other colors and panel styles. Nothing for sure yet, though. If you’d like to weigh in I’ve put a poll at the bottom of this post (link to the poll) - My Instagram poll came back with 35% for white, 65% for black.

So here’s the roadmap (with most completed tasks excluded):

Complete

  • Finalize PCBs & panel design

  • Make 2x personal builds with final PCBs & panels, tested working properly

Next steps

  • Waiting on a quote for custom enclosures (Personal models were painted, but I’m looking to have these enclosures in black and/or white from the manufacturer for a myriad of reasons.)

  • Create a demo video with personal pre-production models to show off capabilities & different capture methods

  • Open up pre-orders for a couple weeks

  • Close pre-orders and do first production run

  • Open store for regular purchases after first production run

The timeline for all of this is pretty loose and depends on when/what I hear back from the enclosure manufacturer, which will hopefully be soon. Also depends on when I’m able to get a video demo together. Pricing is still undetermined until cost of enclosures can be nailed down. Things are beginning to open back up here in Brooklyn so I’ll also be getting back to work at Avant Gardner, so my schedule may start filling up but I’ll be pushing to start proper production ASAP!

Hope you’re all doing well out there!

My DIY Modular Video Synthesizer // Overview video, demo

in ,

Finally - after stopping work on this thing last December I’ve finally got a video about it to share.

Via the youtube description:

“Been a long time coming! Happy to finally get a basic demo together for this build I made over the course of a few months last year. Hope you enjoy! Might make more videos or stream about this thing in the future to explore some of the things I glossed over and show some other things it can do.”

More info about the build can be found here

Upgrades to GVS006, "The IFD" from last November

in

Via gleix.net/ifd -

“The IFD came back to me for a few minor feature additions (kill switch for up/down/left/right CV inputs, composite video input & select switch) as well as a custom CNC’d front and rear i/o panel“

Sync Eater // An analog glitch effects processor

in ,

Via gleix.net/synceater

The Sync Eater is an analog video effects processor with a focus on glitches and visual experimentation. This personal prototype, built into an abomination of an enclosure, was made using the first round of prototype boards. The finished version will feature PCB mounted controls, a standardized front panel, CV implementation, and maybe a few other features. Will be released sometime soon-ish.

More info on this devices page. More to come!

Music video released: "Dividing Space" by Murcof

in , ,

Very excited about the release of this project today, a music video produced for Murcof.

Visual system sequenced and composited from a collection of brief moments in the choreographic work Contre-Mondes by Guilherme Botelho's Alias dance company. The final video was processed using a custom built piece of analog visual effects gear, the Sync Eater. More info on that soon.

Big thank you to Murcof for involving me in this project.

Gleix Video Synth #9 // Ｖａｐｏｒ　Ｄｒｅａｍ ビデオシンセ

in

So excited about this release - I really couldn’t be happier with how this one came out. Check out this build over at it’s dedicated page in the visual devices section!

Via the Vapor Dream page:

This device, dubbed “Ｖａｐｏｒ Ｄｒｅａｍ,” is model no. GVS009 and is a sort of spiritual successor to the 100PFB in terms of aesthetics. With a dual mode oscillator, RGB assignable noise generator, audio input, and CV integration for color and image shift controls, it resembles The I.F.D. as far as functionality goes, but trades out the glitch patch-bay for an attachable mini LCD monitor. The monitor has its own hook-ups for power and video and it attaches to the top of the device via a magnetic base which hold it safely in place. This model, unlike all previous, runs on 12v.

The I/O includes 2x composite video output (primary & monitor), VGA output, an external audio input (1/8” and 1/4”), a 12v 2.1mm barrel jack for power, and another barrel jack for powering the monitor.

March, 2021.

In other news, I’ve been slow with the update blog and social media the past month or so, mostly due to current projects being future releases or commissioned works I can’t share, or things that aren’t ready to be released just yet, but it’s not for a lack of projects for sure. Also been on a bit of a break from social media which I’ve needed. Really excited about a few things I’ve got in the works though!
