"SPIN is an AI music synthesizer that allows you to co-create compositions with a language model, MusicGen. It is a playful invitation to explore the nuances of algorithmic music, encouraging you to slow down and zoom in on its artifacts. It celebrates the marriage between human and machine creativity through music.

SPIN breaks down the process of co-composing music with an AI using a tangible interface. Enter the desired mood, genre, sounds and bpm to listen to the music come alive on an LP record. A DVS (Digital Vinyl System) allows you to slow down, zoom in, scratch and listen between the notes. Use it to create new compositions, as a simple sound synthesizer, as a playful scratch tool, or to play relaxing music in the background.

SPIN is an artifact from a future where music will be hyper-tailored to people’s tastes and preferences. It is an explorer of musical curiosities that can generate music unlike anything heard before, blending unheard-of combinations of sounds, rhythms and harmonies. This opens up exciting possibilities for pushing the boundaries of music and creating entirely new micro-genres. Who’s ready for some happy, death-metal, disco?

Under the hood, SPIN takes the input prompts in the form of button presses through an Arduino Mega. This is sent via serial to a Raspberry Pi which prompts the MusicGen API. An mp3 file is received as the output which is loaded onto a Digital Vinyl System (DVS). A transmuted Numark PT-01 and a timecoded control vinyl record serve as the turntable. The Xwax DVS package for Raspberry Pi reads the vinyl timecode through a Behringer audio driver, and the output is played via stereo speakers.

There are a lot of amazing generative music experiments, from Dadabots’s relentless death metal streaming AI on YouTube to Holly Herndon’s experiments around voice transplantations. But I realized we hit a tipping point when I stumbled upon the Riffusion music model; I was taken aback by its depth and realism, including its new update that adds lyrical voices to the output. Inspired by this, I wanted to build a platform to let me further explore and combine never-before-heard combinations of music and sounds. This laid the seed for building SPIN.

I wanted SPIN to encourage people to be playful; having a scratch interface served this purpose. A DVS (Digital Vinyl System) adds an extra dimension while listening to the generated compositions. It allows us to slow down these synthetic tunes and listen between the notes. So, I decided to combine a DVS system with the MusicGen API in the form of an old-school synthesizer."

Zonoxious Deep Dive Part 1: Project background & Frontend with VCV Rack


video upload by Ultratroninator 3000

"The initial video in a deep dive series provides background info and details how the Zoxnoxious analog synthesizer works. The focus is on the frontend, VCV Rack, and getting the signals required to run the synthesizer from VCV Rack out to a Raspberry Pi.

Project code and docs: https://github.com/brer-rabbit/zoxnox..."

Zonoxious Deep Dive Part 2: Raspberry Pi Gadget Mode with 54 audio channels + MIDI

video upload by Ultratroninator 3000

"This second deep dive video on the Zoxnoxious synth goes into detail on the Raspberry Pi's gadget mode. The Zoxnoxious synth receives 54 control voltages as USB Audio and also USB MIDI for commands. This video shows how that is setup and used. To show the Pi gadget mode working I pull in VCV Rack and roundtrip signals from a host computer to the Pi."

Raspberry Pi based installation art: the melody that started at the beginning of the universe


video upload by Floyd Steinberg

"'Pentatonic Permutations' ( https://pentatonic-permutations.de ) is a piece of algorithmic piano music that's performed in installation art using a Raspberry Pi-based hardware player synchronized to DCF77, an over-the-air time protocol. In this video, I sit down to talk with its creator, Benjamin Heidersberger, about the technical intricacies, artistic intents, the history of algorithmic music and how media consumption has changed over the last decades.

00:00 hello
00:46 interview - how the hardware player was made
03:08 does the development of technology pave the way for art?
04:21 artist intentions
06:49 coding the algorithm
09:06 how the web player / app was made
14:16 short demo: using the midi out function of the app with some synths

Simple rhythmic variations w/ Hologram Microcosm, Dirtywave M8, MT-32 pi, TX-6 & RK-006


video upload by Arman Bohn

"Generative patterns from the M8 are producing the rhythms and bass. M8 is also sending random chord information to the MT32 pi. The MT32 is playing back an E piano soundfont that is sent through the microcosm.

The microcosm is kind of like my therapy right now. I can feed it generative random stuff and play with the knobs and occasionally make some really magical sounds."

Picophonica — A Raspberry Pi Pico synth for a toy keyboard, with instrument presets and Midi out


video upload by Turi Scandurra

"A friend gifted me a cheap toy musical keyboard. The sound quality was atrocious, and it could only play one note at a time. So I removed its circuitry while keeping its enclosure, speaker, and keybed, and with some tinkering and a Raspberry Pi Pico I turned it into something usable.

I integrated a software synthesizer into the Pico. It's pico_synth_ex by Ryo Ishigaki - ISGK Instruments. The new engine boasts two oscillators, featuring descending sawtooth and square waveforms, a customizable filter with resonance control, cutoff modulation, a Decay-Sustain amp envelope, and an LFO for added modulation possibilities.

This video shows the makeover. The soundtrack is entirely played on the Picophonica, recorded one instrument at a time through the new audio out port.

【自作シンセ】アナログライクなFMシンセサイザーをラズパイPicoとArduinoで作ってみた。OP-F Synthesizer


video upload by Harumio 1529

Harumio also brought us the DIY Prophet 4.

"趣味で作ったオリジナルのシンセを紹介する動画です。
OP-FのFは、4オペレータであること、ラズパイ1個当たり4polyである、福岡で作られたこと、僕の頭文字であることなどから名付けました。
いままでで一番編集が大変でした。最後まで見てね。"

"This video introduces an original synth that I made as a hobby.
The F in OP-F was named because it has 4 operators, 4poly per Raspberry Pi, was made in Fukuoka, and is my initial.
This was the hardest edit I've ever done. Watch till the end."

Zynthian V5 improvisation


video upload by Floyd Steinberg

"... using the internal sequencer.
Using the #ZynAddSubFX plugin mostly, but also #Linuxsampler for the drums and piano.
Some TAL Reverb III for those big rooms.
#Zynthian V5 will be available later this year. Zynthian is an open source synthesizer powered by Linux and various free and commercial plugins, all wrapped up in a sleek-looking box with a unified UI and a number of sequencers. If you don't want to buy the kit, you can also download the system image and build one yourself using a #raspberrypi 4.

Broken beats w/ Pikocore, Dirtywave M8, Roland J-6, TE TX-6


video upload by Arman Bohn

"More experiments with the pikocore. Random chord triggering sent from the M8 to the J-6. The Pikocore is synced to the J-6 which is clocked to the M8.

I’m syncing key changes to the random chords as well. I think I’ll continue down this path towards actual pseudo random song creation … so possibly more M8 + J-6 combos in the near future. The modulation options on the J-6 are nonexistent sound design is incredibly limited. I could use another mini synth instead, maybe the great conjunction, or the kasser arcade. but that would take more cord wrangling in the m-8."

This is the first post to feature the pikocore.

Acids RAVE - Realtime Audio Variational autoEncoder


video upload by Realtime Neural Audio Synthesis - embedded RAVE #2 Acids Team - Ircam

From the makers of Neurorack.

"Official implementation of RAVE: A variational autoencoder for fast and high-quality neural audio synthesis (article link) by Antoine Caillon and Philippe Esling.

RAVE comes with two command line utilities, resample and duration. resample allows to pre-process (silence removal, loudness normalization) and augment (compression) an entire directory of audio files (.mp3, .aiff, .opus, .wav, .aac). duration prints out the total duration of a .wav folder.

Once trained, you can reconstruct an entire folder containing wav files"

"Demonstration of realtime embedded RAVE models on different platforms:

- Raspberry Pi 4 8GB
- Nvidia Jetson Nano 4GB

With RAVE + nn~ you can embed realtime neural audio synthesis inside single board computers !

RAVE project: https://github.com/acids-ircam/RAVE
