Jacking Circuit Tracks into Google Gemini AI—DAWless Chaos in Real-Time!

video upload by LucaTronico

"So… what happens when you hot-wire a Novation Circuit Tracks into Google Gemini Music AI (Lyria) over Web MIDI and tell them to play nice?

Answer: they don’t.

Instead you get a live, DAW-free roller-coaster of broken genres, AI hallucinations, surprise crashes, and the occasional moment of pure synth bliss. 🤖🎛️💥

This isn’t a 'click-and-generate' demo—the AI is running in real time, riding (and sometimes derailing) every knob twist I throw at it.

Is it techno? Vaporwave? Polka-drum-&-bass? Nobody knows. But it’s weird, it’s raw, and it’s 100 % unrepeatable."

MOD2 Prototype test | Seeed XIAO RP2350 based Drum module for eurorack

video upload by HAGIWO

":Almost all of the programs were generated by ChatGPT.
Since the circuit has been simplified, there are few CV inputs and the audio is output via PWM, but the RP2350 is fast enough that even a simple program can produce reasonably good sound.

Although there are no plans to use it as a VCO, it also supports V/oct.

Meet the minichord Benjamin Poilve

video upload by Seeed Studio

"This project made by Benjamin (https://buttondown.com/BenjaminPoilve) is a pocket-sized instrument that allows anybody to create nice sounding chord progressions. While it is very simple in its usage, it has a lot of musical capabilities. There is an online interface to customise the preset sounds.

The repository for the project is there https://github.com/BenjaminPoilve/min...."

"The minichord has :

21 main chord buttons, divided in 7 column of 3 buttons;
1 "sharp" button (on the top left).
Each column of the main chord buttons is associated to a note of the C Major scale. It is indicated by the letter on the first row of buttons.

Each row of the main chord button is associated to a chord type:

the first row will produce major chords;
the second row will produce minor chords;
the third row will produce 7th chords.
By following the row and the column of each button, we can identify the specific chord associated. Here is the full table of the chord available by the push of a single button

The harp touch zone is divided in 12 different section, stacked vertically. Touching each section will trigger a note. Notes can be held by keeping the contact with the section.

This touch zone can be "strummed" by sweeping the finger across all sections, or individual notes can be triggered.

The preset selection buttons can be used to switch between preset. The minichord has 12 internal preset (see "Default presets"), that can be replaced by custom presets (see "Making custom presets"). Going up after the 12th preset will circle back to the first, same as going down before the first will circle back to the 12th.

The main led will shine with a different color for each preset to help you identify the current selected one.

Each of the three potentiometer has one main function, designated by the marking on the enclosure :

The first potentiometer from the top sets up the volume of the chord section;
The second potentiometer from the top sets up the volume of the harp section;
The third potentiometer from the top is assigned to a different function for each preset, depending on what is usefull for it.

The rythm mode button (on the top right) has two basic mode:

discrete: the chord only stays on for as long as you keep the relevant button pushed. In that mode, the indicator led will be off.
continuous: the chord will keep playing until you push a new button, and seamlessly switch to the next chord. In that mode, the indicator led will be on.
Simply push the rythm mode button to switch from one mode to the other. That button may also be used to switch to the arpegiator mode with a long push, but that subject is handled in the "Advanced usage" section.

Charging is done through the mini USB jack available on the buttom right of the minichord. Connection to any USB outlet will do, and it will draw 500ma of current.

When charging, the top right led will shine red.

Full charge should be below 3 hours, and the top right led will shine green once the full charge is attained. Once fully charged, the minichord will play for around 7 hours.

When the battery is getting low, the main led will pulse. Once the pulsing start, the minichord can play for around 15 minutes more. You can play the minichord while plugged in."

The frequencies of OSC1 and OSC2 are always in a relative position relationship, and detune and overtones can be added by shifting the frequency of OSC2.

OSC1 FREQ POT: Adjusts the reference frequency of OSC1 and OSC2
OSC2 FREQ POT: Adjusts the frequency of OSC2 relative to OSC1. Can be set from 0 oct to 2 octs above.
OSC2 volume POT: Adjusts the volume of OSC2
OSC2 volume CV in: CV input for adjusting the volume of OSC2
Wave push SW: Selects the wavetable. 16 types in total.
V/oct IN: V/oct input, range is 0~5V.
OUT: Audio output, range is Vpp10V.

The selected waveform information is stored in EEPROM. When the power is turned on again, the last selected waveform is selected."

John Chowning, Computer Music, DX7 & FM Discovery

video upload by Anthony Marinelli Music

"It was an honor for me to interview John Chowning who is directly responsible for the way we create music today in every genre! His visionary ideas have profoundly shaped contemporary music creation, including the integration of computers, AI, digital synthesis, sound sharing, and surround sound.

He stands as a monumental figure in 21st-century music, renowned for his pioneering contributions as a composer, musician, and educator. As the founding director of the Center for Computer Research in Music and Acoustics (CCRMA) at Stanford University, Chowning made groundbreaking strides in the field. His historic discovery of FM synthesis not only became one of Stanford’s most valuable patents but also paved the way for Yamaha’s DX7 synthesizer through their licensing of FM sound synthesis technology.

Another important aspect of Chowning's work is the simulated motion of sound through physical space creating an illusion of a continuous 360-degree space using only four speakers. John’s boundless curiosity and groundbreaking achievements have established him as a bright shining beacon of inspiration for musicians everywhere.

Are A.I. Generated DX7 Sounds Good? Digital God or RoboBozo?

video upload by Off The Matrix

"There's a lot of hype and anxiety over the development of A.I. The A.I. generated DX7 sounds expose the limitations. Much of the hype is fueled by a childish want for new toys without a maturity of developing skills of tools one already has. In the terms of Steve Jobs, it's creation of B and C players.

MUSICGEN AI Generated Electronic Music

Two MUSICGEN AI generated releases in via Liquid Sky Berlin.

First up:

AI sessions #01 - brainFKK noise - entirely created by AI by Gehirn Bernstein featuring MusicGen & Dr Walker

"all sounds you hear were generated with and by MUSICGEN
an AI freeware
arranged and mixed in ableton live
100% of the income of this release - well.... its not a "real" release - more a kind of test what is possible - goes into the Liquid Sky reforestation project.

so lets go & plant some trees!"

2nd:

#AI techno #01 - created with artificial intelligence by djungle fAIver

"Fresh from the digital womb of MUSICGEN, an AI that spins "text-to-music", comes this experimental release.

We kicked off with our hopes tuned to minimal, questioning if this machine intelligence could vibe with our underground ethos.

But, damn, the bot surprised us, spitting out raw, pulsating bad ass underground beats that made our speakers throb and clip.

On track 02 & 05 we cheated :
on track 02 we added a drumloop in the background as the AI generated loops didn t have much high freqs.

On track 05 we sprinkled in a touch of 303, just to spice up the synthetic stew. The rest, though? 100% AI machine-crafted. Pure digital grungey dirty noisey artificial intelligence techno, birthed from MUSICGEN's binary brain.

We were only using Ableton for arrangements and mixdown and some FX like eqs and compressors.

Sure, the AI's BY FAR not perfect - but the ride's only just begun.

We did not correct rendering errors from the AI.
Some of the generated loops are really WAY out of timing.

100% of the income from this release goes into the Liquid Sky reforestation.
