Modular Jam #8 Endless Stream

Modular Jam #8 Endless Stream

Tenho vindo a trabalhar nesta animação já lá vai umas semanas, desde que descobri o Stable Diffusion. O que mais gosto neste algoritmo é que corre no collab, e por requerer tão poucos recursos computacionais é possível usar o collab quase ininterruptamente com a versão Pro. Esta animação é uma mistura de prompts e estilos, gosto especialmente de ver a evolução do estilo à medida que a animação avança. Isto deve-se a estar a aprender e a habituar-me às nuances do Deforum, especialmente a possibilidade de interpolação de prompts.
A música é gravada ao vivo.

I’ve been working on this animation since I discovered SD, and later, the Deforum version. What is great is that it runs on collab and because it is low on computational resources, it runs almost endless on collab with the Pro version. This animation is a mix of prompts and styles, and I like to see how the style evolves throughout the animation as I get used to Deforum features, specially the prompt interpolation, for me is a game changer.
The music is recorded live.

Modular Jam #7 Car in the desert

As ferramentas AI tornaram-se muito gratificantes e imediatas, e na maioria das vezes os resultados são supreendentes. Existem tantos parâmetros e detalhes técnicos para explorar que tornam estes processos em viagens intermináveis.

Obtive estas três imagens e pensei que poderia ser um exercício interessante fazer uma foto-montagem, e aproveitar para sacudir a ferrugem das skills de photoshop.

A imagem final está longe da perfeição, mas adorei o processo.

A música é gravada ao vivo por mim.

It’s very gratifying the way AI tools work and interacts with you, and most of the time returns always great results. There are so many parameters and technical details to explore that make this an endless journey.

I came out with these three images and thought it would be a great opportunity to remove the rust out of my photoshop skills. It’s far away from being a perfect image, but it was a great exercise.

The music was recorded by me performing live.

Modular Jam #5 Temple Tsunami // Disco Diffusion

Temple Tsunami

I started to play with Disco Diffusion a couple of days ago, and I really got overwhelmed by its simplicity and power.

This video is composed by a set of short animations, with simple prompts like “Temple sitting on an ocean with a huge tidal wave” or “sitting in the clouds with the form of a tsunami”.

The animations were mixed in After Effects and sent to FlowFrame.
https://nmkd.itch.io/flowframes
Brought everything back to After Effects, re-arranged the composition and stretched everything about 300% and applied Frame Blending with Optical Flow.
This workflow is just an experiment, and not a final recipe. My exploration continues.

The sound was recorded live using a modular system.

Recorded live with a modular system

Edited the mix in Ableton Live, mainly some minor EQ and compressed the mix a bit.
Edited the video in Adobe Premiere to make a proper intro and development.

The same CV that goes to Rings is being compared with ADDAC208 and triggering an Envelope. This envelope opens another VCA channel with a copy of Rings output, connected to Desmodus Versio
Rings Structure is being modulated by PNW attenuated Square wave, connected to ADDAC215 Dual S&H in Track&Hold mode with Slew fully dialed in
Previously recorded Rings output to Morphagene
A random trigger opens the Morphagene VCA, it’s connected to Strymon Magneto

Modular Jam #2

Modular Jam #2

My jam sessions tend to always lead me to deep drones and ambient atmospheres, and its becoming a confort zone, so I’ve been trying to runaway from this place and explore other sonic realms.

Everything was recorded directly from the rack to an Zoom H6, one stereo track for the drums, other stereo track for the rest of the instruments. Edited the drums track in Live, attenuate the hihats a bit and compressed all the mix slightly.

There’s a crossfade on the video, otherwise it would be repetive and boring to watch. Still so much to learn 🙂

The Sounds of Beads

The Sounds of Beads, the Texture Synthesizer

Beads, from Mutable Instruments is well known for not being everyone’s “cup of tea”, and it’s absolutely understandable.

I’ve been fighting with Beads since I bought it, to the point that I considered selling it. But before doing so, and to avoid any regrets I wanted to give a final try, and doing a final effort to at least understand how it works.

Today I see it as a beast that plays a game where he’s the master, no matter what. It’s a beautiful tool to explore and wander.

So here’s my take on Beads 🙂 

Vimana Sequencer

Vimana Sequencer

Vimana is a personal interpretation of a Multi-track Midi Step Sequencer with an Open Philosophy regarding the User Interface

I have been working on this project during the last 4 years, and today, I’m presenting it to the world as it is right now.
Vimana is also my submission to the MIDI Awards 2022.

Below is a list of the main features that are implemented:

16 independent MIDI channels/tracks
Main clock, division/multiplication per track
Step parameters: pitch, velocity, gate, retrigger, repeat, chord, inversions, sustain
Play mode: forward, reverse, pendulum, random, drunk
Built-in Quantizer with many different scales, and also the possibility of setting a custom scale.
Euclidean Generator

Vimana stands upon an open philosophy regarding the physical user interface. As a developer and a musician, I wanted to be able to build multiple instruments according to the need of the project, or the moment. For this I have created a modular user interface from the physical point of view, but also from the software point of view. Let’s say that we need a step sequencer with 5 steps and 3 tracks only, or a gate sequencer for drums and rhythms with as many steps and pages and tracks, it is all possible with this system, it’s just a matter of changing variables and voila. CPU is the limit here, and since we have a Teensy platform as the brain, we have a lot of free ground to play with.

In the video below I have an intrument ensemble in Ableton Live, and I’m using Vimana to play them all. 

Other instances and prototypes of Step Sequencers, testing different layouts and user interfaces.

The video below shows how it all started, the 1st prototype of a step sequencer. When I accomplish this concept, I knew I could create something way better.

Drone Engine

Drone Engine

I have an Axoloti core for a couple of years, I never gave good use to it. The time  finally came. I have been thinking in a Drone Machine, something that could be fun and simple to use, with a lot of ground to explore and play. On the other hand, I also want to build a generic physical setup, that allows me to change firmware and experiment with new sound objects and synth architectures.

The Axoloti Core is a bare bone pcb, built with a powerful DSP, and it is made to be hacked and customized. It has a great community, that has been creating a huge amount of amazing sonic objects since the beginning. I don’t think I have invented anything, I only connected ready made objects like the oscillators and the effects, it is that simple.

This is the physical setup, it is a Teensy LC with two groups of 16 pots that are connected to multiplexers. Teensy is sending MIDI CC messages to the Axo, and all the parameters are being controlled this way. The major drawback is the MIDI low resolution (127 steps), this is noticeable in the oscillators pitch. One thing to do in the future is to connect the pitch potentiomers directly to the analog input on the Axo.
The black PCB boards I’m using were developed during Artica’s days. Luckilly I still have a bunch of these boards with me. 

Since the Teensy is connected to the Axo via USB (Axo has USB host port), and I didn’t want to have the usb plug showing on the back panel for several reasons, the USB is soldered directly to the Axo’s PCB.

If I still need to program the Teensy, I can still use a modified USB cable that connects to this JST header.

The Axoloti program is very simple, basically there’s 2 oscillators based on Mutable Instruments Braids algorythms, and a third very simple oscillator. Each of the Oscillators has dedicated LFO’s to the filter, and the Mutable Oscillators has also LFO to modulate color and timbre.
Than all the voices are mixed and send to Delay and a Reverb.
If you have an Axoloti and want to experiment this synth, you can download the patch here.

With a MIDI keyboard this synth can be played normally. By the time of this video I had the 3 oscillators being affected by keys, but right now only one oscillator receives MIDI information, so I can still play around with the other 2 as drone voices.
