This is Takazudo Modular Highlights vol.2 (distributed June 8, 2024).
Since our last newsletter was in March, this covers updates from April through May.

ADDAC System Restocked & New Products Added
Several sold-out ADDAC System products have been restocked, and we've added new products as well. What we carry from ADDAC System isn't necessarily their latest releases — we're gradually adding products from their existing lineup. The selection is centered on basic modules chosen by Takazudo, and we've prepared fairly detailed descriptions for each, so please check them out.
The restocked items are modules that customers purchased after we started carrying ADDAC System. They're all useful, and ADDAC112 VC Looper & Granular Processor in particular is quite a unique module and a granular processor worth exploring in depth. I've also written a detailed article, so please give it a read.
Among the newly added products, most are basic modules, but ADDAC210 Open Heart Surgery is a specialized module for module developers. I actually stocked this because I wanted it myself, but I think it's a very interesting module for anyone who does their own development.
Records, loops, and processes audio with real-time control of speed, pitch, and granular processing. A CV-controllable complex audio processor for freely deconstructing and reassembling sound.

Standalone frame for the ADDAC112. Enables use of the looper & granular processor without a Eurorack case. Dedicated design with power supply and controls.

Development platform for Eurorack electronics enthusiasts. Breadboard equipped with all components needed for Eurorack development.

4-channel quantizer with intuitive button operation that lets you use it like an instrument. Packed with chord generation and advanced features for deep exploration.

Versatile mixer for flexible addition/subtraction/averaging/offset of two input signals. Two pairs of 2-channel summing bring your CV processing ideas to life.

Module that converts input signal volume changes to CV, with gate-controlled envelope output. Reflects the dynamics of external sound sources across your entire patch.

Simple utility module for manually generating gate signals. Multiple channels for flexible live performance and improvisational patching.

Utility module for controlling latch states via button operation. Provides convenient switch functions for holding and toggling gate signals.

Noise-driven 4-voice drum module. Generates snare and hi-hat-like sounds, adding gritty texture and character to rhythm tracks.

Percussive sound source module utilizing T-network filters. CV-controllable decay per channel for generating diverse drum and percussion sounds.

Module that converts 4 gate signals to trigger signals. Provides conversion for patches requiring short pulses, enabling more versatile gate signal handling.

Weston Precision Audio Now Available
We've started carrying Weston Precision Audio modules, and the full inventory has been added to the shop!
Originally, Takazudo Modular planned to buy DIY kits from this brand, build them ourselves, and sell them. However, Devin (the maker) wanted the build quality and the value of each unit being hand-crafted to be part of the product's worth, so we agreed to sell built units instead.
Once the products arrived, I immediately understood what Devin meant. Weston Precision Audio modules are all built with carefully selected materials, each one assembled with great attention to detail. Anyone who's bought various modules will probably notice right away.
For example, cheaper panels are often made from FR-4, the same material used for PCBs, but with more investment, you get options like aluminum. Weston Precision Audio panels have a smooth surface finish on metal, giving them a premium feel. The panels and PCBs are likely intentionally made thicker for a solid, substantial feel. They even include washers between every nut, use switches that give a distinct tactile feedback, and many other thoughtful details.
Currently, the product descriptions are rough translations from the official website, but we plan to update them one by one as we verify each module's operation.
Analog harmonizer that generates two related pitches (such as thirds and fifths) from a VCO input, adding simple harmony and basic polyphony to a modular system. Also usable as a dual quantizer, frequency-to-voltage converter, or dual analog VCO in 18HP.

Analog VCO built on a triangle core with a triangle phase-animator circuit offering 0–180° adjustable phase delay. Supports through-zero linear phase modulation (PM), linear FM, and exponential FM in an 18HP oscillator that sculpts harmonics through phase modulation.

Dual voltage-controlled filter usable as two independent VCFs or a stereo filter. Each channel offers nine output responses, a link mode, and a CV-controlled panner/crossfader for spatial filter processing in 18HP.

Dual 16HP analog oscillator with two identical triangle-core VCOs, both capable of through-zero FM. The right VCO hard- or soft-syncs to the left, plus each VCO offers an LFO mode and six waveform outputs.

Six-voice analog drum module inspired by a vintage Japanese machine sharing its number. Packs Kick, Snare, Hand Clap, Closed/Open Hi-Hat, and Ride Cymbal into a compact 16HP footprint.

14HP synth voice for crafting deep kick drums and cutting basslines alike. Includes a 1V/Oct VCO with four waveforms, a 3-wave mixer with a sub-octave sine, dual fast-switchable AR/AD envelopes, a high-quality VCA, and a multi-mode VCF.

Analog ADSR envelope generator triggered by a standard gate signal. Lets you independently choose log, linear, or exponential curves for each A/D/R stage, giving a 12HP envelope module a wide range of shaping options.

Triangle-core analog VCO with through-zero linear FM support. Delivers a wide tuning range, excellent thermal stability, and both classic analog tones and complex TZFM timbres from a simple 12HP oscillator.

Acrylic Modular Cases and Blank Panels Now Available
Additionally, I, Takazudo, have started selling some blank panels and acrylic modular cases that I made as a hobby.
The acrylic modular cases come in two types: one with high-quality rails, and another designed to fit TipTop Audio Z-Rails 84HP dimensions. If you're starting out with modular synths or want to add to your existing setup, please consider them.
Assembly-type acrylic modular case, 84HP. With rails.

Assembly-type acrylic modular case, 84HP. For Z-Rails.

Affordable and durable 3U aluminum blank panel set, large sizes.

We plan to send one more newsletter update this month. And just between us, it seems Mercari Shops will be running another 10% off sale this month. When that happens, currently listed products will again be 10% off. Mercari Shops is quite generous...! The next newsletter will probably go out around that timing. Stay tuned.
See you next time.
