PAIA 9710 ADSR MIXER and PSU in METASONIX DRAG
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"This is a homebrew from kit Paia 9710 mixer with noise source and envelope generator. It is encased in a standalone yellow box in the spirit of early Metasonix pedals.. The case also has the PAIA power supply board to power the envlope generator board.
[manufacturers description]
The PAiA 9710 is a versatile module that combines three VCAs, a white noise source, and a full-function ADSR envelope generator. It allows for mixing signals before processing with the VCA, making it a compact solution for various sound design needs.
The PAiA 9710 is a multifunctional module designed for sound synthesis, combining several key features that enhance its versatility in music production.
Key FeaturesFeatureDescription
VCAsIncludes three Voltage Controlled Amplifiers (VCAs) for dynamic sound manipulation.
White Noise SourceProvides a built-in white noise generator for additional sound textures.
ADSR Envelope GeneratorFull-function ADSR (Attack, Decay, Sustain, Release) with adjustable parameters for shaping sound.
Mixing CapabilityAllows mixing of multiple signals before processing through the VCA, streamlining setup.ADSR Specifications
Attack Time: Adjustable from 500 microseconds to 5 seconds.
Decay Time: Ranges from 2 milliseconds to 7 seconds.
Sustain Level: Adjustable from 0 to 10 volts.
Release Time: Adjustable from 2 milliseconds to 7 seconds.
Trigger and Gate Inputs: Separate inputs for re-triggering the envelope.
Cycle Switch: Enables self-triggering for Low Frequency Oscillator (LFO) functionality.
The PAiA 9710 is ideal for musicians and sound designers looking for a compact and efficient solution for creating complex sounds and effects. Its combination of VCAs, noise generation, and a comprehensive ADSR envelope makes it a valuable tool in any modular synthesizer setup.
The envelop can self cycling (always on) or activated by trigger or gate voltage pulses."

Inertia Synthesizer
video upload by Zack Berwick
"So after seeing Author and Punisher live earlier this year, I felt inspired to build my own drone machine.
These controllers consists of a 2lbs aluminum rod attached to a optical rotary encoder, while sitting atop thrust ball bearings. This encoder is then wired to an Ardunio Uno R3 measuring the RPM value along with it's rotational direction. I then used that data to control a synth patch I made in Max Msp 9 using the abl.drift and abl.roar objects along with two DMX controlled light panels using the Beam max package.

Grip! A legendary compressor redesigned by Izhar Ashdot and Claude AI
video upload by Izhar Ashdot Sound & Vision
"Grip! My take on the LevelLoc compressor. I designed it and let Claude Code handle the coding and debugging."
Additional details from Izhar:
"Here’s a new compressor I built with the amazing help of Claude Code.
It’s a modern and fine tuned homage to the legendary Levelloc.
It sounds like an analog beast but is actually hosted on a Pi Pico 2 microcontroller. "

Meet Acid Drip - A DIY Bassline Synth & Drum Machine
video upload by Marcus Dunn
"Check out the GitHub Repo if you are interested in building your own
GitHub - https://github.com/lonesoulsurfer/Aci...
Instructables - Coming soon!"
Note: Acid Drip is based on the BadAss basS Synth and DrumKid featured further below.
"An RP2040-based acid bassline synthesizer and drum machine built on the Mozzi audio library. Two instruments in one device, a 16-step acid sequencer and a 16-pattern drum groove box running simultaneously on dual cores with a 320×240 ILI9341 TFT display and 16 Cherry MX pads.
NOTE: the images of the synth are V1. V2 is what I hve provided in this repo and looks a littke different (extra pot for mix added)"

Tropical Fish Wurlitzer Document Archive
This one is in via Paulina Salmas from Tropical Fish who had the following to say;
"I am working on a project that I thought you might be interested in.
I am a keyboard tech, and in 2022 I visited a warehouse packed to the ceiling with Wurlitzer organ parts. The warehouse had been owned by a former Wurlitzer employee, but it had recently been sold, and the new owners intended to destroy everything inside on the following Monday. There, I purchased around 100,000 Wurlitzer Co. engineering drawings that would have otherwise been incinerated.
The drawings include dimensions, material specs, and associated paperwork for parts in every Wurlitzer organ, electronic piano, and accessory, including the Sideman drum machine. I am scanning the pages so that the information can be made available to other techs and musicians, to help them repair vintage Wurlitzer keyboards and keep them alive.
About 2,000 drawings are available here, and I will be uploading more as I scan them: https://www.tropicalfisharchive.com."

New product reveal: A physical control surface for MIDISID.
video upload by MIDI IN
"Nobody likes menu-diving, right? This is an add-on for MIDISID which gives you physical controls (analogue pots and sliders plus prophet-style buttons) for most of MIDISID's functionality.
This is an expensive thing to build, and I don't know how many to plan to make. Therefore, I'll be running a 'threshold pre-order campaign' over the next couple of weeks.

pikocore v2 firmware
video upload by infinitedigits
"pikocore has a brand new firmware that will work on all pikocore devices or pikocore remixes.
the firmware has two major changes:
1) total revamp of the "stretch" to an amazing sounding grain-based timestretch and
2) a sample manager that works over usb in the browser! no need to reflash firmwares when changing samples.
simply connect to a website (https://pikocore.com), and add/delete/rearrange your audio files in the browser (chrome works best). additionally if you are using the ittybittymidi just click a checkbox on the sample manager.
diy kits still available at https://shop.infinitedigits.co/
source code full open-source: https://github.com/schollz/pikocore"

Korg MS10 with two useful modifications
video upload by Lackan
"The Korg MS10 is a fantastic synth in the same range as the CS5, Axxe and S60f but it has a flaw imo; when inserting an EXT CV-source to the VCF, the envelope is gone as a modulation source. This video introduces a way to solve this - and some more."
