Ultratroninator 3000 shutdown sequence with Easter Egg

video upload by Ultratroninator 3000

"To shutdown the Ultratroninator 3000 hold down the three right buttons. A shutdown countdown starts, and the buttons must be held for the duration of the countdown otherwise shutdown is aborted.

Here's an Easter Egg I added to the Ultratroninator 3000. Release the keys and abort the countdown just a fraction of a second before the timer gets to zero. The LEDs start doing a Conway's Life thing, which is interesting 'cause it's mapped to the 14 segment displays. The three rows of 8 discrete LEDs are also included."

HAINBACH's New Filterbank Is the Size of a Piano

video upload by HAINBACH

"German HiFi Manufacturer Teufel was getting rid of the analog system they used to design crossovers for their loudspeakers. I could not pass up the opportunity to get this piano-sized analog filterbank in my studio. Together with @LOOKMUMNOCOMPUTER I explored the musical use of this gigantic piece of obsolete technology.

PAIA Modular Synthesizer with Keyboard, Cables, and Documentation

Note: Auction links are affiliate links for which the site may be compensated.

via this listing

"This is a mid 70's PAIA Modular Synthesizer, these were originally sold as build it yourself kits, and all of the modules were sold separately. Included in this build is a wide variety of modules that PAIA had available at the time.

There are manuals and instructions sheets for all of the modules, and the keyboard. Also included is many of the voltage and audio patch cables.

Both devices power on, however when looking it over I tested with a volt meter and found the voltages to be low. For example: They power supply is supposed to output 9V and 18V on two separate outputs - but my test showed 5V and 13V out.

That is all the testing I did and concluded that this Synth needs some servicing. Either a transformer or power rail issue apparently."

[$9] DIY eurorack modular synth opto compressor | vactrol type optical compressor

background
The 78th work of my own modular synth.
One of Eurorack's standard modules is MATHS. One of the uses of MATHS is Envelope follower, but this Envelope follower is difficult to use properly.
I have created an Envelope follower in the past. This time, I decided to create a compressor as one of the application examples of Envelope follower.

Opto compressor
Compressors include VCA and FET as means of compressing audio, but there is also a type called opto compressor that uses Vactrol (analog photocoupler).
Although the responsiveness is poor, we decided to create an opto compressor this time because it can be created inexpensively with few parts.

Product specifications
Eurorack standard 3U 6HP size
Power supply: 20mA (+12V), 20mA (-12V)

opto compressor using Vactrol LCR-0203.
The idea is to use it to increase the sound pressure by compressing the entire MIXed audio, or to change the impression of the sound by compressing a single percussion sound such as KICK.

THRESHOLD: Adjustment of the level at which compression starts.
RATIO: Attenuation rate adjustment. By increasing RATIO, it is possible to compress at a magnification of 1x or less. In other words, the louder the input audio, the lower the output can be.
RELEASE: Adjust the RELEASE TIME of the built-in Envelope follower.
VOLUME: Audio out amplification. Lowering the THRESHOLD lowers the overall volume, so the VOLUME POT compensates for the volume drop.
LED: The more compresson is applied, the brighter the light will light up.
Also used for calibration.
IN: Audio input. It is assumed to be used at Vpp=10V (-5V~+5V).
OUT: Audio out

Production cost
Total about $9

LCR-0203 $1
Front panel $1
Envelope follower module $2
Variable resistance $0.3*4pcs

"Monkey is a pocket sized Bluetooth MIDI keyboard. It has several built in unique MIDI effects, a drum machine and a looper. Each of the effects is equiped with 10 different algorithms. Monkey is optimised for low latency and low power consumption, enabling several months of usage without changing the battery. It connects to lots of hosts including macOS, OP-1F, ipadOS, Windows and Android.

We believe Bluetooth has great unutilized potential. But we can not tap into this without making Bluetooth very easy and practical to use, and providing high reliability. Monkey is our first product which taps into this. From our perspective we don't see a bunch of Bluetooth-centric MIDI devices on the market. This is the core idea from where Monkey originates from: lets make a device which only connects via Bluetooth and explore which new form factors and workflows spores out of this idea."

MadLab Bleep-o-Tron DIY Synth! \\\ Patch Flip & Tweak ///

video upload by midierror

You might recognize the name from a 2016 incarnation posted here. See the MadLab label for additional creations.

"This phase modulation synth costs $45 !!?! Take a quick tour tweaking some patches for the excellent Bleep-o-Tron (Redux) from MadLab! This is a DIY kit you solder yourself, which has some pretty impressive features. It's a polyphonic synth with 5-Pin MIDI In, 3.5mm audio out and built in effects (Flanger, RingMod & Delay).

There is a superb editor for the synth, which not only alows you to control various elements of the synth, but also copy/paste them to different sections! The video does have audio glitches and held notes, due to the playback of multiple MIDI notes during the tweaking - these by no means affected my enjoyment, but are worth mentioning.
