The SSSR Labs Mult 2×4 is a passive multiple module having switchable configuration: 2×4 or 1×8. This module has the smallest possible width: only 2hp, which perfectly allows it to fit yet another gap in a modular synthesizer with useful function.
The color coding helps user to select desirable operation mode.
Black lines, left switch position: Dual 4-terminal multiple.
Blue lines, right switch position: Single 8-terminal multiple.
Specifications of assembled Eurorack module:
Module width: 2hp
Module depth: 15mm (0.59″)
Net weight: 25g (0.9oz)
Module dimensions: 129x10x29mm (5″ x 0.4″ x 1.12″)
Eurorack and Arduino. What common may be between a huge analogue rack and a brains for a toy robot? Perhaps it is openness of the both platforms and broad variety of existing solutions based on them. Nowadays it is not something outstanding to use a digital controller inside analog module, but Arduino also is respected for its simple and user-friendly development tools, allowing to create a device doing random tasks for minimum time and money. A couple of years ago Arduino chips had took their place in Eurorack modules. 4ms, Flame use AVR controllers in their products and Soundmachines specifically used Arduino to develop their Robotto and had published an SDK for it.
And now appeared modules that are intended to be programmed by owners. The first one was utility-module Expert Sleepers Disting ($175), based on PIC32MX uC, then Circuit Abbey Euro-Duino ($145), based on Arduino as it comes from the name. The price for the DIY kit of this module is just $95 and it has lots of fun within! So, let’s take a closer look at the module. Continue reading →
High-tech eurorack module Matrix Mixer by latvian company Erica Synths should appear by the end of July. Module is a hybrid matrix DC-mixer, controlled with 3.2″ touchscreen. Analog part consists of 10 DC-coupled inputs and 8 DC-coupled outputs. The main interface resembles 10×8 Synthi-style matrix with virtual pins, controlled by touches. This pins connect respective input and output with unity gain. it is possible to store up to 256 patches — individual settings, and to create a performances — chains of settings, which can be succeeded by single or pre-defined serie of pulses passed to Clock input.
Belarusian electronics designer Alexey Laman manufactures Eurorack modules under L-1 trademark. His modules are highlighted both by himself and by community members as top-quality modules comparable to Cwejman products. The Company is founded in 2012. Today’s model range includes several dynamic effects (compressor, VCA, mixers), VCF and even vocoder! Modules can be purchased as fully-assembled units or as DIY-kits. In this review I’m going to introduce three L-1 modules at once: 2180VCF, Quad VCA/Mixer and Tube VCA. Continue reading →
New version of alternative firmware for ACXSynth MIDI2CV has been released. Changes (from v. 5.5):
Pitch bend now works in all modes.
Aftertouch assignable to CV2 Out.
2-voice Split mode at Channel +4 in Multitimbral mode.
2-voice Intellectual duophonic mode at channel +5 in Multitimbral mode.
Fixed bug with Voice two acting as Trigger in polyphonic mode.
MIDI Clock Rate is now adjustable
Version display at startup (0101.0111)
Parameters can be stored into EEPROM
The first key pressed at Split mode channel defines split point (the most lower key of the upper zone). Lower zone goes to voice 1 and upper zone goes to voice 2. Split point is set each time when multitimbral mode is selected. Intellectual duophonic mode can be used with two identical voices. Converter analyzes each newly pressed key and assigns corresponding note to particular voice where most closer note was taken previously. This makes it possible to play douphonic parts with glide with no unwanted slew between the parts if there is sufficient space between the hands. This mode doesn’t require fixed split point, but there is no binding between voices and parts like in the split mode. When monophonic part is played, only one voice will be used, there is no unison! New version can be downloaded on the Project page
Thanks to all donators! I mean it, thank you, guys! I’m glad to create as perfect code and design as I can.
Music From Outer Space is probably most famous Synth-DIY website. It’s author, Ray Wilson has developed huge amount of various modules and can offer wide variety of DIY-kits: module PCBs, noise generators, complete modular synths and even vocoder. Today I’m gonna tell about Eight Stage Phase Shifter module which Eurorack version I had pleasure to build recently.
