Semi-modular synths are great, and even with a sizable eurorack set-up I find myself gravitating to these complete, self-contained instruments more and more, to get the enjoyment of patching without the option paralysis that a full modular synth sometimes inspires.

Nevertheless the big benefit that a full modular set-up gives you is that expandability and flexibility to build out what your setup is capable of by adding or swapping out modules.

But semi-modular lovers need not feel left out! There are numerous bits of kit out there which can help you get more from your semi-modular synths, expanding their capabilities and sonic palettes.

ST Modular Introduces CV EXPERT (Dual Polarizer, Offset & Gain + LFO, 4HP)

video upload by Stefan Tretau

"Sound examples are not supposed to be musical, but merely represent the voltage changes audiovisually.

00:00 Intro
00:05 Features
00:56 Polarizer, Offset, Gain
02:06 LFO Rate
02:36 Voltage Monitor"

CV EXPERT is a very compact yet powerful CV tool that is equipped with all the important functions you need to customise your control voltages. With its internal LFO, it is immediately ready for use without further patching.

CV Expert (Cve) is a versatile dual-channel tool for customizing control voltages.

Its internal LFO is normalised to both inputs and allows you to choose between a triangle or square wave via a jumper on the back. The LFO connection is automatically interrupted when an external CV is inserted. Adjust the LFO rate with the LFO RATE potentiometer.

The signal received at the DC-coupled inputs IN ① and IN ② passes through three CV tools:

Polarizer
The PLRZR potentiometer enables voltage attenuation and inversion.
At the midpoint, the signal is eliminated.
Turning to the right allows the original voltage to pass through (as with an attenuator).
Turning to the left inverts the signal, e.g. positive signals are converted into negative signals.

Offset
Adds or subtracts voltage from/to the passing signal.
OFFSET control determines the offset range.
In the center position, there is no voltage offset. Turning the control to the right shifts the voltage to the positive range, while turning it to the left shifts it to the negative range.

Gain
Amplifies the signal with a maximum gain of 2 at the GAIN control's maximum position, effectively doubling the applied voltage (e.g., +1V becomes +2V, +3V becomes +6V, or +4V becomes +8V).
The voltage is capped at a maximum of +/-10V.

"The CONTROLLER module is a versatile four-channel CV control unit designed for precise management of up to four external CV parameters. Serving as a centralized control hub, it eliminates the need to individually access each control destination, streamlining the control process and enhancing workflow efficiency.

Four slider potentiometers are provided, each offering a travel length of 45mm. These sliders enable the application of unipolar voltages ranging from +0V to either +5V or +10V, which can be selected via a jumper located on the module's rear. Adjusting the slider upwards increases the voltage applied to its respective OUT socket, with the slider LED indicating the voltage level.

In addition to the sliders, each channel features a STRIKE button, allowing for the immediate application of a predetermined voltage on top of the voltage set by the slider. The maximum additional voltage that can be applied via the strike button is adjustable using the S MAX controls, ensuring seamless customization. This feature enables users to effortlessly set the desired voltage level to be activated with a simple button press.

The Controller utility is a convenient tool specifically crafted to manage multiple parameters of various modules, enhancing their accessibility during live performances.

Inverted echoes (a modular patch idea)

video upload by Electrum Modular

"The aim here – besides trying out the TSNM as an expressive keyboard – was to generate an inverted echo, so that a descending melody comes back as an ascending one, or vice versa. (I stole this idea from Bach, who often used contrapuntal inversion, playing the theme “upside-down”).

Mutable Instruments’ Beads (in delay mode) is perfect for this, but any module with a long delay would work. The other crucial ingredient is a multi-channel mixer/attenuverter such as Make Noise Maths (here, I’m using Acid Rain’s Junction).

ST Modular - KRAKONG (Duophonic Semi-Modular Sonic Voyager)

video uploads by Stefan Tretau

"KRAKONG is a duophonic generative synthesizer with a sequencer per voice, FM crossover modulation, an additional random modulation sequencer, one multimode filter with VCA, a buffered multiple and a resettable LFO. The design includes a collection of manual controls and connections for patching and CV control.

Each of the unit's two voices consists of a triangle and a square wave oscillator, a shift register sequencer, a decay envelope generator and a filter-based gate. In addition to the two synthesizer voices, which can be manually distributed in the stereo field, a third ring-modulated output of the two voices can be mixed to the main output. The tempo of all sequencers is determined by a clock generator, which can be controlled internally or synchronised externally to any voltage (audio and CV).

This musical instrument has a complete structure that allows for a wide range of sonic possibilities, from rhythmic drum patterns and tamed sonic chaos to textural and rough synth-sounds. The essence of this unit lies in the exploration of the interplay between the elements of the synthesiser, using the three sequencers and filters, manual controls and modulation patch points."
