Tags: Quantizer module

Notes: Scales is an 8hp dual-channel note quantizer and step sequencer. Fundamentally, it takes an input voltage, quantizes it to notes in a user-defined scale, and sends that quantized voltage to an output, where you can use it as a melodic pitch source for oscillators or any other module that expects to see discreet note values at its input.

Scales goes far beyond the fundamental, allowing you unprecedented control of the pitches and intervals hiding inside your control voltages; turn LFO's into arpeggiators; random voltages into harmonic counterpoint; and unquantized external CV sequencers into chromatically tuned note sequencers.

Quantization can be locked to an incoming trigger. There are a number of trigger output options as well, ranging from no triggering (good for pitch shifting drones); through triggers that sync with either of the two outputs (or both); to a trigger or gate transmitted in sync with one sent to the module's TRIG input.

Shift:

Scales features two independent outputs, enabling you to create shifted harmonic intervals within your chosen scale using only a single pitch input. Using the SHIFT input you can modulate changes on OUT A and/or OUT B.

You can also use the shift input to switch between scales or to change the root of any existing scale pattern or split Scales into two quantizers - each conforming to a common scale, but fed entirely different voltage sources.

Sequence:

Scales also features a 128-step SH-101 style step sequencer (complete with storage for up to 35 fully programmable patterns) - allowing you to feed OUT B with sequenced notes and rhythm patterns, while OUT A continues to function as a standard pitch quantizer for external voltages. You can even sync the sequencer to quantizer events on OUT A.

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: Tesseract's step sequencer is designed for hands-on playability, configured as a 16-step or dual 8-step design. Unique features include a 'drunk' mode to add variety to your sequences.

Supplier notes:
Step Fader mkII is a 'hands on' eurorack dual sequencer, featuring two 8 step lines or one with 16 steps, plus quantizer, slew limiter, internal clock generator, CV inputs to control any parameter and more...

Each sequencer has independent settings for the play mode, start point, size (length), clock divider (or step repeat), transposition and duty cycle.
There are 16 presets to store & recall all the above settings plus CV input assignment, scale, tempo, step repeat and clock out ones.
The 2 channels of the quantizer can be used for processing external signals, same for the slew limiters.
The 16 illuminated buttons can be used to set several parameters, even to play the sequencer as a keyboard.

There are 3 MAIN SETUPS:
DUAL (2 totally independent 8 step sequencers)
PARALLEL (one sequencer with 2 rows of CV and 8 steps)
SINGLE (one sequencer with 16 steps)

There are also these PLAY MODES:
Normal
Reverse
Pendulum
Drunk
Random

Each sequencer features:
Clock input (clock input 1 is normalised to clock input 2)
Clock output
Reset input
Gate/Trigger output
Slew limiter output (unquantized)
V/OCT output (quantized)

Additionally, there are 2 summing outputs:
Gate/Trigger 1+2 (OR output of both G/T)
CV 1+2 (sum of both slew limiters)

Features 2 CV inputs with offset pots. Assignable parameters are mode, start, size, clock divider, key (the position of the sequencer is controlled by CV), transposition and duty cycle.
