Tags: CV modulation module

Notes: A true legend of modular synthesis, Make Noise's Maths is arguably the definitive Eurorack function generator. Based on analogue computing circuits, Maths draws on Buchla-style techniques to offer countless ways of generating and processing modulation signals.

Supplier's Notes:
The MATHS music synthesizer module is an analogue computer designed for musical purposes. Amongst other things, it will allow you to:

Features

Generate a variety of linear, logarithmic, or exponential triggered or continuous functions

Integrate an incoming signal

With no signal applied, generate a variety of linear, logarithmic, or exponential functions

Add, subtract and OR up to 4 signals

Generate analogue signals from digital information (Gate / Clock)

Generate digital information (Gate / Clock) from analog signals

Delay digital (Gate / Clock) information

If the above list reads like science rather than music, here is the translation:

Voltage Controlled Envelope or LFO as slow as 25 minutes and as fast as 1khz

Apply Lag, Slew or Portamento to control voltages

Change the depth of modulation and modulate backwards!

Combine up to 4 control signals to create more complex modulations

Musical Events such as Ramping up or Down in Tempo, on command

Initiating Musical events upon sensing motion in the system

Musical note division and / or Flam

Perfect for modulating the DPO and just about anything else

Notes: Part of Xaoc's Leibniz Binary Subsystem, the updated Drezno ADC/DAC module builds on the original with higher resolution converters, allowing you to use it for pitch quantisation.

Supplier's Notes:
Drezno II is an improved version of the original Drezno module. It is an essential member of the 8-bit Xaoc Devices Leibniz Binary Subsystem. The Leibniz subsystem is a family of modules that operate on 8 binary (two-state, on/off) signals. These signals are arranged as 8 bits of digital data and may represent analogue signals and voltages, or they may be whatever you want them to be (clocks, gates, rhythms, etc.).

Drezno features an ADC (analogue-to-digital-converter) and DAC (digital-to-analogue-converter), allowing it to act as an analog front-end of the system. In other words, Drezno allows one to convert analogue signals and CVs into digital numbers, as well as to obtain analogue signals back from some other digital numbers (or 8 binary signals). Between these two conversions there is a whole universe of digital shenanigans waiting to happen resulting in all kinds of signal transformations and modulations.

Both (ADC and DAC) sections of Drezno can work independently, or they can be linked. Input and output range of analogue signals may be adjusted using Gain and Offset sliders. Individual bit outputs (for the ADC) and inputs (DAC) allow for extensive cross-patching and the creation of complex waveforms and rhythms. A very fast clock (up to 2MHz) at which the conversions are performed may be replaced with any external clock (for each section separately).

Compared to its predecessor, Drezno II uses new converters of much higher resolution which results in much lower noise floor and higher accuracy. The lower bits are much more stable than before. It is easy now to use Drezno for quantizing pitch voltages with accurate results with 128 or 256 semitone steps. Potentiometer ranges are factory calibrated for precise chromatic scale. A new switch on the front panel allows the user to select the calibrated range of 10Vpp or 20Vpp, so that the lowest bit or the second bit correspond to 1 semitone.

Notes: The MASTER18 is a very flexible generic CV processor.

You can think of the MASTER18 as a smaller and cheaper version of the DROID MASTER without CV inputs and LEDs, but with an integrated USB and MIDI, six additional gate jacks, two of which are inputs and four are outputs.

Details:

It has 8 CV output jacks with a voltage range from -10 V to +10 V, driven by highly accurate low jitter 16 bit DA converters:
2 gate inputs switching at 0.1 V
4 gate outputs switching between 0 V and 5 V
2 MIDI interfaces via MIDI standard B (mini jack)
MicroSD card reader and a button for reloading the MicroSD card
USB C to access the SD card from your computer or to send/receive MIDI MASTER18 comes with two interesting bonus features:
It can be connected to the Sinfonion as a follower of the Harmonic Sync.
It has an integrated tuning device for VCOs (can measure their frequency).

The MASTER18 is a good choice if you intend to just create CVs and don't need to process incoming CVs. It's perfect for building sequencers and MIDI to CV converters. MASTER18 can do almost any CV task you can imagine, such as sequencing, melody generation, slew limiting, quantizing, switching, mixing, working on clocks and triggers, creating envelopes and LFO or other fancy voltages, or any combination of these at the same time. While doing this, is very precise both in voltage and in timing.

You can attach several different DROID controller modules, such as the E4, the P2B8, the P10, the B32, the P4B2 or the M4 in order to get direct hands on access to all parameters and values of these patches.

Easily create your desired DROID patch utilizing our simple and easy-to-use editor with built in tutorials - the DROID Forge. It is available for Windows and Mac (both Apple Silicon and Intel).

The file created with the DROID Forge is a simple text file named "droid.ini" and needs to be loaded on the micro SD card that goes into the MASTER18.
