A serious trigger sequencer for generating complex, multi-layered rhythms. Eight channels of Euclidean pattern generation meet probability, modulation and CV control for real depth and power.

Supplier's Notes:
Constellation is all about rhythm. It is an 8 channel pattern generator that works by combining multiple dense and sparse patterns to create long, complex and musically interesting trigger and gate rhythms. Constellation takes a "parametric" approach to rhythm - there is no explicit step sequencing on the module, rather the rhythms are defined by euclidean (and more) parameters that build the rhythm mathematically.

Constellation aims to evolve the concept of euclidean rhythms far beyond the useful but repetitive patterns we often think of when we hear the term "euclidean rhythm". This is accomplished by by combining up to 8 individual euclidean patterns of different lengths and density. Each pattern may provide only a small component of the final output, but together create immensely musical and varied rhythmic material over a very long time frame - up to 999 steps! If each of those steps are 1/16 note in length at 120 bpm, that's a full 2 minutes of explicitly defined, yet non repeating rhythmic material.

In addition, Constellation's parametric approach allows any of these parameters to be modulated with CV through one of 8 freely assignable CV inputs. CV modulation introduces further ability for Constellation's rhythmic output to vary over time. Paired with a Maestro or Navigators, hours of interesting morphing rhythms are possible without the need for tons of step programming or the uncontrollable chaos of a purely generative approach.

When writing music, rhythmic interest is often built through the combination of repeating and non repeating elements that work together to anchor the overall feel but also keep the ear free from boredom over the duration of the piece. Constellation provides a unique set of tools to accomplish this goal and achieve rhythms that are intentional, unexpected and exciting to use as the foundation of your compositions.

Notes: Erica Synths Black Spring Reverb is a different take on spring reverberation units. Firstly, it has built in vactrol based audio compressor, secondly, it can operate an external tank and combination of both internal and external ones for effects unheard before, thirdly, in order to animate reverb effect, the module has built-in feedback effects - pitch shifters, delay, ring-modulator, etc; feedback amount and effect parameters can be controlled manually and via CV, making the module an experimental instrument on its own. Module comes with compact spring reverberation tank which can be easily installed in most eurorack cases.

Features
Compact spring reverberation tank to install in a skiff case
Manually and CV controlled feedback amount
Vactrol-based compressor
7 distinct feedback effects
Selection between internal, external reverberation tanks or combination of both
Feedback Send and Return jack sockets
The module is designed to be used with wide variety of spring tanks, but the best results will be using tanks with low input impendance - 8-200ohm

Technical specifications:
Audio input level -5V - +5V
CV level (full span) -5V - +5V
Power consumption 43mA, -71mA
Module width 12HP
Module depth 30mm
Internal reverb tank dimensions 190mmx67mmx24mm (30mm with spacers)

Notes: Two channel expander for Bartender

Mixer section

Each channel has the following:

Stereo or mono - Each channel can be treated as a stereo channel or a mono channel with two summed inputs.

CV inputs for both panning and level control

Two send buses - You can route each channel to one of two send buses. Each send bus is stereo. You can choose if you want the send to come before or after the level/panning controls.

Mute - The mute has both latching mute (up) and a momentary mute (down). The mute uses a capacitor to slow the turn off and on of the mute action. So it is mostly click-less, but you may find an occasional pop.

Cue bus - You can route each channel to the cue bus.

Expandable Mixer Series

Bartenders can be cascaded to create 8ch, 12ch, or 16ch mixer. The main level is what is sent the main level control can act as a group control.

Barbacks can be added to add 2ch to your mix. Barbacks can also be cascaded enabling up to a 16ch mixer configuration.

Send-VCA can be added for CV control of the level of the send.

DVCA, Cast Iron, Mingles, and USB-2CH can all be connected with Dupont cables (aka female to female breadboard cables) via pin headers on the back of the modules. Connecting the in and out pins will send/receive the audio into the next module.

Nektar Impact GXP49 Control

DIRECT ACCESS: THE CONTROLS YOU NEED
The streamlined no-fuss control panel is based on the successful Nektar Impact GX-series, enabling advanced DAW integration with extended transport control, track selection and volume control as well as options to open/close DAW windows and navigate songs. In addition, GXP88's user interface also has 14 assignable illuminated RGB buttons for direct MIDI program- and bank-selection.

Impact GXP is a MIDI controller as well as a DAW controller:
If you use MIDI software that's not supported by Nektar DAW Integration, you can also set up MIDI control yourself. The assignable buttons in the transport section can be configured to send out Program message or MMC (MIDI Machine Control) transport control. In addition, any of the 28 assignable MIDI buttons, the modulation wheel, keyboard aftertouch, foot switches and of course the big control knob, can be assigned to send out MIDI cc messages. The settings are stored over power cycling.

GREAT CONNECTIVITY:
MIDI, PEDALS, POWER
The GXP49 gives keyboard players all the right expression options needed for live and studio work. It offers large pitch bend & modulation wheels and connections for up to 3 optional external pedals: Connect any standard expression pedal to the first, and any standard footswitch to the second socket. And if you use an optional Y-cable adapter, the footswitch socket even supports two independent switches.
