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
