Southpole VCV Rack Modules 0.6

1.0 under construction in branch v1 - not yet released

report issues in the Issue Tracker thread

A personal collection of modules I've always wanted for my workflow.

Some of the modules are simply reskins of the existing Audible Instruments VCV Rack versions of Mutable Instruments eurorack modules.
- The skins are inspired by hardware micro versions of various MI modules.
- Some skins are additonal modes of firmware with appropriate labels for knobs and ports to make usage easier.
- Some skins do not exist yet in hardware.
Some modules did not yet exist in VCV Rack versions.
Some modules are new.
Mutable Instruments
Audible Instruments
Extra "Southpole Parasites" for parasites firmware based modules are on a separate branch

Building

Compile Rack from source, following the instructions at https://github.com/VCVRack/Rack.

After checking out in the plugins/ directory, get external dependencies with

git submodule update --init --recursive

There is a build script

./scripts/make_all.sh

WARNING: Overwrites existing Southpole directories from eg. a regular download, inspect script before use

Modules copied from Audible Instruments

Cornrows X - Macro Oscillator

Based on Braids, Manual
Extended as follows
- As complete implementation of Braids / macro oscillator as possible
- so far not available features in the Audible Instruments version have been activated and broken out as controls: AD-envelope, bit crusher, scale quantizer, tuning
- Implemented as menu options: AUTO, VCA, FLAT, Paques

Splash - Tidal Modulator / Lambs - Wavetable Oscillator

Based on Tides, Manual
Based on Sheep (Tides alternative firmware)

Smoke - Texture Synthesizer

Based on Clouds, Manual

Smoke, extra skins for additional modes: Espectro, Ritardo, Camilla

Annuli - Resonator

Based on Rings, Manual
extra skin for Disastrous Peace mode

Bandana - Quad VC-polarizer

Based on Blinds, Manual

Balaclava - Quad VCA

Based on Veils, Manual

New modules

Aux - 2 stereo effect send/return loops

with cross feedback (same or swapped stereo channels)
mute button for input (to listen to those sweet reverb tails)
bypass button for fx (in case you went wild with the feedback pots)

Abr - Manual A/B Switch

Inverse of But, either input A or B goes to output
Sums of inputs set to A or B provided

Blanks

Nothing special right now, but watch this space
42HP useful if you want to recreate a 84HP row common in hardware

But - Manual A/B Buss

Inspired by DJ Steevio's modular method
Either input A or B go to the output and the A/B busses
Two summed identical outputs for A and B buss are provided.

Deux Etagères

convenience stereo version of Etagère

Etagère - EQ Filter

Inspired by Shelves, Manual
Does not fully reproduce all characteristics of Shelves!
Biquad filters copied from RJModules Filters

Falls - Attenumixer

Attenumixverter, inspired by Fonitronik Cascade
empty inputs provide offset voltages
empty outputs mix into output below
Range switch +/-1 or +/-10

Ftagn: No Filter

transgressive module for your nihilistic no-input patches at the noise show
stereo - neither left nor right channel do anything at all

Fuse - Synchronized one-shot triggers

Intended to build a "queue next pattern" system like on groove boxes / drum machines
Helps fire synchronized events in 4/4 based music if you can't count like me
Can be used to launch triggers (or beat-long gates) ONCE at a given beat on a 16 step counter
Arm triggers/gates manually or via inputs
For example, clock with bars, trigger to mute the kick for exactly 4 bars, trigger 4 bar later to drop

Piste - Drum Processor

One-stop module to turn oscillators into drums / percussion, or process existing drums to taste
Inspired by Bastl Skis
Input gain + eq + overdrive because sometimes basic processing is all that's needed
2 independent decay envelopes (eg. body and accent) the sum of which is applied to input signal via internal VCA
2nd envelope is scaled to 1st
Triggers are scalable
Mute input / trigger veto intended for choke groups (eg. open hihat mutes closed hihat)

Pulse: Pulse Generator

main purpose is to convert triggers to gates
clock through sends 1ms triggers - clean your clock
range selectable (1s / 10s)
when clocked, duration/delay are quantized to "musically relevant" intervals

Rakes: Stereo Resonator

inspired by the Ableton Resonator effect
6 stereo comb filters
V/OCT inputs quantized to SEMI tones or FREE
FINE detuning works with opposite sign on L/R channels
small values produce Haas effect (stereo widening)
individual GAINs
best used together with a chord generator patched into the V/OCT inputs

Riemann

chord generator based on Neo-Riemannian Tonnetz analysis
inspired by NE Tonnetz Sequent, Navichord app, o_C Automatonnetz (and my incapability to compose / improvise diatonic music)
Traversal via perfect fifth (P5/V) per volt and major triad per volt (M3/V) inputs
Major/minor, Augmented/diminished chord groups
3 - 7 parts per chord (from standard triads to thirteenth chords)
Parts mostly display for now, outputs after last part output root note
Switch for suspensions (sus4) close to fifth-axis
Transpose rotates within octave
Outputs in V/oct
Tonic output (T) for tonic drone
Voicing inc/decreases octaves to the right/left sequentially by part (small settings to the right give chord inversions)

SNS - Euclidean Sequencer

I know. but this one looks cool and has a few additional features:
Up to 32 steps
Accents: nested euclidean sequence on main sequence
Rotate sequence and accents
Up to 32 pads (silent steps)
All inputs scaled to each other in what i think is a sensible way - great for LFO modulation of inputs
CLK/RST thru for easy chaining
Turing mode to translate pattern into CV a la Turing Machine

Snake

16 internal busses 0-F with 10 lines per buss to bridge large distances or generally tidy up the patch
First connection to input locks input (green led - red on all other instances)
Works best with slow signal. In case of parallel processin check difference between original and bussed signal by means of inverting summer and scope

Sssh - Noise / S+H

4x noise / S+H - inspired by the lowest section from Kinks
Triggers are normalled from top to bottom
Inputs are normalled to noise
Noises are four calls to generator (not a copy)

Wriggle - Spring Model

Follows input with a given stiffness and damping of the spring
Mass normalized to one
Output can be scaled/offset
Designed to implement "Woggle CV" (works best at LFO rates)

Gnome - Synth Voice

An all-in-one module inspired by MFB Nanozwerg
Because sometimes you just need the basics and want to get started fast
The submodules are mostly copied from the Fundamental modules with some omissions and additions:
VCO: analog part of Fundamental VCO, morphing
Sub-OSC 1/2 Oct / Noise
LFO from Fundamental LFO, morphing + S+H
ADSR from Fundamental ADSR
Biquad VCF with resonance gain-compensation
