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.

Craig Padilla - First Light Over Aurora (Live) - MST/Division6, MatrixBrute, MPC ONE, Modx M
video upload by Craig Padilla
"Please consider donating a much appreciated monetary tip to the performer to:
PayPal.me/CraigPadillaMusic
Trick or treat! Here we go again with another live performance in the studio! This time it's inspired by the spirit of Halloween! And, once again, it's been captured on video by Colleen Padilla.
'First Light Over Aurora' was performed in front of my wife's parents. Colleen had suggested that they should be here for this recording because they hadn't personally experienced one of my live performances. Thankfully, they enjoyed it. And their energy in the room during the performance was inspiring. It's always a treat for me to be able to play my music for others in a live setting.
This song features heavy use of four synthesizers and effects:
Akai MPC ONE
Yamaha MODX M7
Synthrotek MST & Division 6 Modular with Source Audio Collider
Arturia MatrixBrute
Hologram Microcosm
TC Electronics Ditto X4
The Mattson Mini Modular and ARP 2500 Sequencer modules are here on display, but they were used for another epic track, 'The Trench Protocol'.
This song will be available on my new live album 'The Trench Protocol - Live'. It's available at www.CraigPadilla.com."

M-VAVE FM-1 | Official V16 Firmware: A Multitimbral Beast! (Stereo FX & New Presets)
video upload by NatLife Sounds
You can find the M-VAVE FM-1 on Amazon.
"New "Ambient & Dreams V2: Analog Vibes" soundbank (Official release tomorrow + new Video-demo): https://natlifesounds.com/product/amb...
Download V16 Firmware: https://www.m-vave.com/download
So, I'm pleased to present the official release of firmware B16 for the M-Wave FM-1, which includes the following major changes:
8-Part Multitimbral Architecture: You can now layer up to 8 different sounds or play 8 independent patches simultaneously via separate MIDI channels.
Expanded Polyphony: Total synthesis voices increased from 12 to 20, dynamically shared across all 8 parts.
Upgraded Sequencer Grid: Up to 64 steps (increased from 16) with a brand-new 8-track, 8-column arrangement layout for seamless live playback.
- Global Stereo FX Architecture: The 6 built-in effects are now fully stereo. However, they now function as a single shared global FX chain for all 8 voices. Changing individual voice presets no longer alters the shared FX settings.
Per-Voice Tuning & Pan: Each of the 8 parts features independent volume, level, pan, and fine-tuning (-100 to +100 cents).
Expanded MIDI CC Control: Added support for MIDI CC11 (Expression), CC7 (Master Volume), and dedicated CC70–93 range for external FX modulation.
Enhanced Workflow: Features direct patch import/export, DX7 standard SysEx (.syx) bank transmission, and customizable RGB UI color schemes.

Every FM-1 Firmware Should Be as Easy as Melodee
video upload by substatica drones
M-VAVE on Amazon
"Building a loop and going over some features of Melodee, an intuitive groovebox firmware for the M-VAVE FM-1. The Melodee firmware expands the FM-1 with five sound engines, including Prophet-style synthesis, 6-operator FM, CZ, SID and drums, alongside a four-track, 64-step sequencer. It also adds recording, effects and hands-on sequencing tools designed to make building complete loops fast and intuitive.
MELODEE Firmware - https://keremimo.github.io/melodee/we...
FM-1 is a true frequency-modulation synthesizer in your pocket. Six independent sine-wave operators combine through 32 algorithms to recreate the iconic timbres of the FM era — pianos, strings, brass, basses and electronic synths. It comes loaded with 128 factory tones and a color TFT screen that draws the live algorithm structure and oscillator waveform. A 27-key silicone piano-layout keyboard with OCT-/OCT+ over 8 octaves, MONO/POLY voicing (up to 12-voice polyphony), six built-in effects (Filter / Reverb / Delay / Distortion / Chorus / Phaser), a 7-mode arpeggiator and 16-step sequencer turn it into a complete creation rig."

Speak and Key Speak by Max for Cats
video upload by max forcats
Speak
Speak is a polyphonic Max for Live instrument that turns typed words into speech in the style of a 1980s Speak & Spell. It encodes each word into coarse chip-style LPC frames and decodes them live in eight voices. MIDI notes set the pitch, so any word can be played as a melody or a chord. It speaks six languages (English, German, French, Italian, Spanish and Japanese), and it can freeze a vowel, stutter at any point in a word and apply a 10-point modulation curve. Vibrato has several shapes and a fade-in, and there are controls for tract size, tilt and intonation.
SpeakKeys
SpeakKeys uses the same voice engine, but each of 48 MIDI keys has its own word and its own pitch instead of speaking one word chromatically. You type a word and a semitone pitch for each key, and a note shows the note that plays it and the note that sounds, so you can program little songs and play them from a keyboard or a clip. The keys are laid out in four banks of 12 and are saved with presets. A pair of mappable Select Key and Select Pitch controls lets you edit all 48 pitches from a few Push encoders. It shares the language, vibrato, global pitch and tone controls with Speak. Max for Cats crafts Software Instruments, Effects, MIDI devices, Sound Design and Samples for Ableton Live.
