The VoltRatio 1V/OCT CV input allows you to quickly and easily switch through exactly 6 harmonic degrees. Additionally, this module enables you to obtain both a copy of the fundamental frequency's voltage and a frequency one octave below simultaneously, allowing you to comfortably control up to 3 oscillators at once. Furthermore, designed as a precision multiple, this module offers precise and professional calibration options, helping your system stay in accurate tuning and advancing both you and your system.
The frequency ratio system, which can also be found in the first digital examples of Thru Zero Frequency Modulation and allows easy adjustment of harmonic degrees in all operator oscillators according to the fundamental frequency, is crucial for maintaining musical and tonal compatibility. This system greatly simplifies programming in complex FM patches. With the three separate outputs designed as Vaemi, which replicate the 1V/OCT CV input like a precision multiple and provide different degrees, you can use all analog thru zero or standard voltage-controlled oscillators. Quickly navigating between harmonic degrees during recording or live performances will provide significant musical and practical advantages. The output providing harmonic degrees (Ratios) includes 2 buffered outputs, making a total of 4 CV outputs on the module.
You can adjust the desired voltage and harmonic degrees between 0-6V according to your preferences and needs using the trimpots on the back of the module. Additionally, you can set the -1 OCT output to the desired negative level using the trimpots on the back.
All inputs and outputs of the module are DC coupled. Essentially, the module adds or subtracts an offset voltage to the voltage entered into the 1V/OCT CV input. We can think of it as a precision CV adder-subtractor. The sum of the entered and added voltages is what comes out of the outputs. In short, you can also use this module to shift the offset, process signals like envelopes or LFOs, and more. (Note about the module: one of the most important points is that it has both positive and negative outputs and precise calibrations for offset and CV scale. So, it’s not just about adding offset voltage to the voltage.)
You can read which channel you are on from the top of the module or easily determine it with the help of LEDs. The module is 10HP wide.

Vaemi's new module XFMR VCA, which is designed for Eurorack systems, introduces users to a transformer-based VCA design.
Turkey-based Vaemi (Volt Age Electronic Musical Instruments), which commercially produces synthesizers and electronic musical instruments, recently released its first module, the Osi-Op (through zero fm VCO), and quickly followed with other Eurorack modules such as Shift Register, R2R Ladder, Buffered Multiple, making a name for itself. Now, it has introduced and brought its users the new XFMR VCA module, which is handcrafted with high-quality, through-hole components and features an audio transformer in its output.
The XFMR VCA is a VCA with linear curves. It has two separate audio outputs, such as the classic Op-Amp and the Transformer Output feature that gives it its name. It is AC Coupled and designed specifically for audio signals, making it a VCA module that you would want to use at the end of your chain. You can use it to add saturation, harmonics, and EQ to your patches made with the Osi-Op and through zero fm techniques, or use it for a clean range if desired. This wide range of options will be loved and make you feel comfortable.
Additionally, the XFMR VCA has an expander that allows you to expand it up to 3 channels. With the expander, you can have two more exponential VCA channels, which you can use for frequency modulation of oscillators or in other places you need them.
In studios, preamplifiers are equipment that can properly raise the microphone or line signals level without distorting or adding noise to the sound. However, when recording analog synthesizers, we tend to lower the sound instead of raising it because they have very high outputs. At this point, we thought that one of the most important things that preamplifiers add to recordings, other than gain, is audio transformers.
The XFMR VCA also has an EQ stage. This will provide great flexibility when finalizing your last patch, especially in multi-channel patches, and will provide a more accurate and clean sound in live performances.
Vaemi aims to create systems that can comfortably be used in today's electronic music and popular synthesis techniques such as additive, FM, Formant, Subtractive synthesis, and will continue to shape and evolve with new module designs that will be released in the coming year.

Shift Register essentially stores the data in binary form, and it shifting the data in accordance with a clock signal reference. In fact, thanks to this feature, it is used for storing, adding, subtracting, multiplying, and dividing data in a computer. Multiplication and dividing are actually the results of the shifting process.
Shift Register is a module that is designed for Eurorack systems, and it can run between 0V-+5V. It runs with a clock signal. This way, all the data entered through data input is synchronized with the starting and ending times of the clock signal. This module is a dual and 4bit Shift Register module. It can be accepted as a 4-step sequencer. The jack on the module that types data is input.Even if you enter a CV signal or gate signal, the signal you will get from the outputs is a 5V gate signal. The first output, on the other hand, gives out exactly the same pattern you entered in the data signal, only a better-synced version with the clock,while synchronizing with the clock signal, it shifting the written pattern to another output as the clock arrives. In fact, as a result, when you enter 16-note clock signals, you get a 16-note delayed version of the pattern you typed from each output. If you use this module in the audio rate range, you can run it like an oscillator with clock signals that are hear able for human ears. In this way, while patching with square waves in Logic, you primarily get different phase degrees of the data (square wave) you entered.
@modular01 power specifications are exactly as written and written correctly. 5V is not used in the module you gave for example.
-- Vaemi
this "5V is not used" should be inserted as 0 mA
its impossible to distinguish between zero mA and missing information when you keep this field empty
thank you!
-- modular01
hello, thank you for your attention. Also, thanks for the warning. We fixed the issue
You can now find Vaemi among manufacturers on Modulargrid. To do this, click the Modules tab in the Eurorack category. You can search from the Manufacturer section.
Buffered Multiple is an active signal multiplication circuit. Thanks to this module, for example, you can create many copies of an 8Vpp signal out of a single 8Vpp signal. You can use this module as two 1 In – 4 Outs or one 1 In – 8 Outs. Signal flow is shown on the module with arrows so that you can use the module without difficulty. As long as you do not plug in a jack through the input below, the input of the first channel on the top is directed from the inside, through the circuit board. The module is DC-coupled. Therefore, it can be used for all AC and DC signals, and all audio and CV signals.
The first company to produce synthesizers and electronic musical instruments for commercial purposes in Turkey, VAEMI (Volt Age Electronic Musical Instruments) has introduced Osi-Op, which is the first Eurorack module with high-quality Thru Zero FM and a different Waveshape feature. This module is made by combining through-hole quality components and it is handmade. Osi-OP, which we regard as an analog reflection of the new era of digital electronic music, is an analog and voltage-controlled oscillator module. It was designed in Eurorack format and it has a width of 14hp. It has Thru Zero FM Input and a Waveshape Output, which can be used for morphing, and these are two of the most important features of this product. From a first impression, it may look like an oscillator that is appropriate for subtractive synthesis. However, it was actually designed to be used for additive synthesis. Thanks to Thru Zero FM, this oscillator can regard oscillators with Sine Wave as analog operators. You can even prepare your synthesizer patch without using the classic subtractive resonant filter. The most important aspect of Thru Zero FM is that there is no tune drift when you increase the modulation rate. For this reason, Thru Zero attenuator (TZ FM potentiometer) can almost be used like a filter itself. In addition to Square, Saw, Triangle, and Square Sub oscillator outputs, it has a Sine Wave Output, which was designed with JFET transistors and has a very low distortion rate, and a Waveshape Output, which was designed with Sine-Triangle and can be used for morphing. It also has a Wave Shape Input. It is connected to this input via the Triangle Wave circuit board inside. Sine Wave is fixed on Wave Shape but you can forward it to the other WS Input by patching other waveforms, and you can morph between two waveforms. The pulse width of the Square Wave can be adjusted. The same knob is the morphing knob of the Waveshape Output. Since the oscillator has tempco, there is a 1V/OCT calibrated CV Input that is sensitive to heat. It can perfectly stay in tune up to 3.5 octaves. In addition, for FM, there are two separate CV Inputs, Exponential and Thru Zero. While Exponential FM CV Input can take all types of DC and AC voltages, Thru Zero FM CV Input can only be used for AC audio rate signals. Also, when you enter a waveform on Thru Zero FM CV Input, oscillators are soft-synced automatically. With 1V/OCT CV Input, you can adjust the frequency of the oscillator; and with Exponential FM CV Input, you can easily add an LFO or Envelope Generator. Square Wave Sub OSC Output, which is completely synced with fundamental frequency and can give an octave lower than the fundamental, will help you a lot to create strong modern synth-bass sounds. It is made with NOS integrated. When the oscillator is FM modulated, the Sub OSC never gets negatively affected by this modulation; and it can maintain giving the frequency clearly. You can also switch the oscillator to the LFO mode. You can create subtractive syntheses by using two or more of these oscillators or by mixing these waveforms. The main reason why this oscillator was designed, as its name shows, is to enable the creation of complex FM patches and sounds by using 2-3 or more of these oscillators, just like Operator FM. While Thru Zero FM increases the modulation, it can maintain giving the same frequency without losing the adjusted frequency; and you can add harmonics to the sound musically. The module has 5 knob controls, 4 CV Inputs, an input for Waveshaper, and 6 ±5V waveform outputs. Osi-OP, which is handmade and produced with the help of Through Hole technology, is a product consisting of electronic components that are carefully tested.
