PlantsSystem-FiveGenerativeVideo


video upload by plantssystem

"Here is a digest video of five generative sound pieces I made for the Raspberry Pi Pico 2 (RP2350). Each one is a self-contained instrument: switch it on and it plays by itself, with a small screen showing what is happening and a joystick and four buttons to steer it on most pieces.

Hardware: Raspberry Pi Pico 2 (RP2350) with a Waveshare Pico-Audio board for stereo audio out and a Waveshare Pico-LCD-1.3 (240x240 display, joystick, A/B/X/Y buttons). All sound is generated on the Pico 2 itself; there are no external synths or samplers. The firmware is written in Arduino (arduino-pico core).

The pieces in the video:

AMBIENTWS: Switch it on and just listen. An endless ambient piece that breathes in Japanese scales (hirajoshi, miyako-bushi, Ryukyu) and Maj7 progressions, layering a granular voice, a physical-model voice and a pulse/rhythm voice, and pausing now and then to catch its breath. It can follow USB MIDI clock.

AZIMUTH: Clicks, sine pings and noise bursts tick like a glitching heartbeat, with a kick, bass and arpeggios racing across the stereo field. Patterns repeat bar by bar and renew every four bars, or can be frozen in place.

GIBSON: A recorded voice keeps talking until it shatters, stutters, reverses and bit-crushes for a few seconds, then calmly picks up where it left off.

LAWRENCE: In an empty room a grand piano quietly composes. Each melody is heard once, and a new piece is born at every start.

PROPHETIQUE: A 5-voice polyphonic generative sequencer built from a single Prophet-5 note. Four tracks play the phrases of an original song, and as you change how many notes are dropped, the playback direction and how pitches are chosen, the song unravels, rearranges itself and drifts away from the original.

The source code is not public. The pieces are shared only as firmware with a few artists for their own work and live use.

Erica Synths LXR-02 Firmware is Now Open Source



via Erica Synths

"The LXR-02 drum machine firmware is now open source and available on the Erica Synths GitHub! We live in an era of "vibe hacking", where Al-assisted tools let musicians and developers alike reshape software in ways that were hard to imagine only a few months ago. With that in mind, we have decided to open the LXR-02 firmware to the community. We are curious to see what new ideas, features and approaches emerge, and where this experiment will take the instrument. We invite you to explore the code, experiment with it, and share your results with the community."

Small box, big tunes.

ARP Odyssey SUB-oscillator


video upload by Lackan

"This SUB-oscillator PCB was originally designed for the Oberheim SEM, but will work on most vintageanalog synths.
Depending on synth, installation may vary, this video shows the installation in an vintage ARP Odyssey.
The installation is fully reversible and leaves no ugly marks on the synth."

DYI Wersi Wersivoice BBD triple chorus on Solton Project 100


video upload by ohm-studi-ohm

"This triple chorus uses Panasonic MN3004 BBD chipsets, the same used in choruses / ensemble fx in the Roland Jupiter 4, RS-09, VP-330, Korg Polysix, Trident and some more.

This one is an ensemble fx and gives you instant string synth sound.

I demo it with a Solton Project 100 which is a extremely nice sounding 6 voices analog polysynth (which btw has a wonderful built in stereo triple chorus not used in this video but I will demo the synth in a future video).

Hop Tactile - touch and play- Brooklyn SPEXPO 26


video upload by sonicstate

"Saima from Hop gave us a look at Tactile, an open-source standalone synth from Hop, developed from work in classrooms at Daniel's Music Foundation, a nonprofit working with disabled musicians.

Tactile is wireless, includes its own speaker and comes in light and dark colourways. The playing surface is pressure sensitive and has nine zones. The edges play a major scale, while the centre acts as a random sequencer. Additional areas control half-step bend, octave bend and a single-stage looper.

Patch changes use physical texture pads, with each pad linking a tactile surface to a matching sound character, including smoother and more bit-crushed responses. Key cards transpose the instrument; it defaults to A and changes key when a card is inserted.

Tactile is available from Hop's website. A separate Tactile Sidekick is in prototype and adds CV and MIDI interfacing for Eurorack and controller use.

Soothing Ambient Synth Meditation | Isochronic Tones for Deep Calm

video upload by Smomid

"Soothing ambient synth meditation, performed live on glowing handmade synthesizers. Gentle isochronic tones, slow pulsing filters and soft bells to help you relax, unwind and find deep calm.

Use this music for meditation, relaxation, stress relief, yoga, studying, focus, or winding down before sleep. Isochronic tones work through regular speakers, so you don’t need headphones (though they sound lovely with them).

Everything you hear is played live, with no loops or pre-recorded tracks. The rhythmic filter movements are synced to the tones, and the LEDs respond as the music evolves. I synthesized the bell tones as well. All the audio was created using Pure Data open source programming software.

🎛️ About the instruments
All the instruments used in this video were designed and handmade by me. The blue boxes I call Pyramidi and the guitar shaped instrument I call a Smomid. There is some info available about these instruments at my website: Smomid.com"

OPEN-1 Concept


video upload by RedtailWorks

"OPEN-1: one synth, every firmware.

OPEN-1 is an idea for an open, entry-level synth: a 37-key instrument that becomes a new machine every time you pick a firmware from the SD card. In this concept video it runs a simulated HYP-1, in time with a real HYP-1 live take.

IDEAS PHASE: OPEN-1 is not a product yet. Nothing is for sale, the renders are concept art, and every spec and price below is a target, not a promise. I'm sharing it early to find out what you'd want from it.

TARGET SPECS
480 MHz Cortex-M7 (STM32H750), open toolchain (the FM-1 runs at 240 MHz)
32 MB of working memory for long delays, loops and samples (the FM-1 has about 432 KB)
16 MB of firmware flash plus a microSD library: keep several firmwares installed, swap from the menu
24-bit stereo audio in AND out, so it can be an effects box too
MIDI in and out (3.5 mm TRS), USB-C device and USB-C host
37 RGB-lit silicone keys, 8 velocity pads, 8 endless encoders, a thumbstick and 2 spring levers
4" 480×320 IPS screen, built-in speaker, headphone out, 3000 mAh battery
Wired only, no Bluetooth: lower latency, simpler to build
Target price: under $200

OPEN BY DESIGN
An open SDK and a browser emulator, so developers can build firmware before the hardware ships
A firmware jam before launch, with a community-voted firmware pack preloaded on every unit
Launch firmware ported from the FM-1 family: HYP-1, LOF-1, ECO-1 and GRAV-1

TyCoon Sequencer Part 1: Teach In


video upload by TheAnalogmonster

"First video of my newest development, an Oberheim Two Voice Pro Sequencer inspired MIDI and CV sequencer for my TyCoon system. Smartass I am I added improvements and additional features:

• The sequencer manages several sequences in parallel, limited by the EEPROM size only.

• There is no sequence maximum length. The sequence lengths are limited by EEPROM size only.

• The sequencer operates with two different sequence types: Voltage sequences and MIDI sequences. Voltage steps are created via CV / NOTE potentiometer and STEP STORE trigger, MIDI steps via TEACH IN. The last records a MIDI sequence from an external source (other MIDI sequencer, keyboard etc.).

The steps are defined as voltage step or MIDI step by a corresponding step attribute bit.

The sequences are defined as voltage sequence or MIDI sequence by the corresponding attribute bit if its first steps.

• All sequence(r) data are kept in EEPROM automatically."

altstrument - A directory of custom and third-party firmware and tools for music hardware.



via the creator of the site:

"I just launched altstrument.org, a free directory of custom and third-party firmware and tools for music hardware.

It lists 544 custom firmwares and 88 host-side tools (editors, flashers, SDKs) across 120 devices from 45 manufacturers: Elektron boxes, Akai MPCs, Korg's logue synths, norns and monome, Mutable Instruments and Noise Engineering modules, the M-Vave FM-1, the Music Thing Workshop Computer and more. Each entry records who made it, where the source lives, its license, its version history and whether it's still maintained. The site links to the projects and never hosts firmware files.
