Synthetic Sound Labs Announces 2655 Geo-Gruvn EUCLIDEAN EURORACK SEQUENCER



Press release follows:

"SSL’s new 2655 Geo-Gruvn is a six channel, 16 step Euclidean rhythm / gate sequencer for Eurorack modular synths in only 6 HP.

Geo-Gruvn is inspired by the brilliant efforts of Japanese designer Hagiwo, and produced by SSL with kind permission. SSL has also significantly enhanced the hardware and software leading to better performance and improved functionality.

Each of the six output channels allow adjustment of:

Hits – The number of outputs generated, with Euclidean spacing. Offset – Changes the starting point for the Euclidean sequence. Length – The number of steps for this channel before resetting. Mute – Turns on/off all outputs of the selected channel.

A single rotary encoder allows uncomplicated selection of channels and functions with simple visual feedback provided by a bright blue OLED display.

In addition to its extensive Clock / Sequencing related duties, Geo-Gruvn can respond to Clock inputs well into the audio range, making it a convenient 6-channel frequency divider.

A Pattern Memory screen allows non-volatile storage for up to 8 pattern sequences. Page 1 of 5

The Geo-Gruvn features a bright OLED display, clock and reset inputs, 6 gate / trigger outputs, a rotary encoder for selecting functions, and an eight Pattern non-volatile memory. All inputs and outputs are standard 3.5mm phone jacks with an associated LED panel indicator.

Power is supplied by standard 10 pin Eurorack power header.

Quality, solder masked, fiberglass-epoxy printed circuit boards and meticulous hand- crafted assembly assure years of trouble-free service.

Synthetic Sound Labs has been in the analog synthesizer business since 1973. The 2655 Geo-Gruvn is the newest in SSL’s continuing line of outstanding analog synthesizer devices.

Pricing is $179.95 US and is available off-the-shelf from SSL and Distributors Worldwide."

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

[$5] DIY eurorack modular synth Dual Slew Limiter


video upload by HAGIWO

"My 74th original eurorack modular synth DIY projects.
Dual Slew limiter , I aimed for simple functionality with few components.

Description (Google translated):

The 75th work of my own modular synth.
One of the most basic modules of a modular synth is the Slew Limiter. Eurorack's most popular module, Make noise Maths, also has this slew limiter function.

I have also created modules with Slew limter functionality, but since I have never created a Slew limiter itself, I decided to create one.

Product specifications
Eurorack standard 3U 6HP size
Power supply: 15mA (+12V), 15mA (-12V)

Dual Slew Limiter with two types of functions.
Priority is given to low price and fewer parts.

top of module
Slew Limiter allows you to select the slew rate range from three types.
Select 3 types of range with the toggle switch.
L range: Assumed to be used for slow CV such as LFO
M range: Assuming the use of pitch CV portamento
S range: Assumes the use of an audio frequency low-pass filter
Control the slew rate with Pot.

Supports bipolar input.
Since the accuracy of the output voltage with respect to the input voltage is high, it can be used for V/oct pitch CV.

module bottom
Slew Limiter allows you to set Rise and Fall slew rates individually.
It is assumed that ASR envelope generator will be used.

Supports bipolar input.
Due to the circuit, the accuracy of the output voltage with respect to the input voltage is low. The use of V/oct pitch CV is not assumed.

Outdoor modular synth ambient jam | with new DIY travel case


video upload by HAGIWO

"I DIYed a new case for my modular synth—a travel case made from an attache case. Power is sourced from a USB mobile battery.

I used the Helical by sdkc instruments as the sound source. This module produces exceptional ambient sounds, which I'm quite fond of.
