New Stuff!

Gluten Free

Gluten Free is an STK-based granulator. It makes horrible, horrible noises. It has six knobs, all of which you can play with. It works best if you load short files and turn the voices up. I wanted to add a V/Oct controller but couldn't figure out how to do that with the framework - want to help?

It's a wild beast, but with enough twiddling, you can tame it and it sounds fucking awesome.

MegaDivider

Mega Divider is a 1:64 clock divider! Also includes two 'multi' divisions, which will generate signals when either of the two divisions are active.

Gaussian

Gaussian is a normal distribution generator! It has 9 trigger outputs, which will turn on randomly when ever a trigger signal or a button press is received, based on the distribution illustrated by the left-hand column of lights, which can be controlled using the Mu and Sigma knobs.

Instro

Instro is a multi-instrument voice generator using the "STK" voices. Uses a variety of different algorithms for different instruments, including FM synthesis and an enhanced Karplus-Strong algorithm.

There is a "gate" input which is required for the plucked instruments (guitar, mandolin, etc.), and there are four different parameter controls for each instrument. Finally, there is a simple wave based drum sampler.

Chorus

Chorus is a simple 3HP chorus effect with CV-adjustable delay time, frequency and depth.

Chorus is the first of a few modules based on the "STK" synthesis library.

Octo

Octo is a bespokely tuned voltage source for organic modulation.

It provides eight phasing waves (0-5v) ranging from quite fast to incredibly slow. There's an integrated attenuvertet so that you can generate complex, self-modifying oscillations.

It also functions as a track-and-hold, as it will sustain the current output values while a -5 attenuated CV input is given, which can be used to create cool stepping effects.

Additionally, in the right click menu, there are multiple waveform types. Square waves can be used to generate random gate/clock signals, which is fun too.

The module is also quite efficient and doesn't use very much CPU considering the number of outputs it has!

Octo is inspired by DivKid's ''Ochd'', which you should buy for your hardware modular.

Euclidian [sic]

Euclidian uses ancient math and nuclear physics to generate tribal rhythms. It's based on this paper: http://cgm.cs.mcgill.ca/~godfried/publications/banff.pdf. Cool! The right click menu provides a bunch of world rhythms out of the box.

Video/audio demo here.

Left Hand Right Hand

Left Hand Right Hand is kind of a strange expierment. It's a MIDI input device with a "split" knob that allows you two divide your MIDI instrument into two separate signal paths. This lets you play separate voices on your left and right hands on a single MIDI keyboard. An experiment, feedback welcome.

Ping Pong

Ping Pong is a clock-synced ping pong delay. Includes dotted and triplet time signatures, a "nudge" knob for making slightly-off delays, and a 0-200% feedback mode which allows you to create amazing - but dangerout - feedback swells.

PlayableChord

MutateSeq / Notes / Sequential

MutateSeq lets you build a sequence that mutates over time. Can lock notes and change rate of mutation. Notes and Sequential work together to build a simple sequencer with different step modes. Can change mode and size of step.

Brickwall

Dry // Wet

Triggerswitch

Synths

ACID

"This thing is amaze-balls!! Been messing around with it for about 3 hours didn't even feel the time pass. Acid goodness 👏👏"

ACID is my take on the legendary TB-303. It features two independent multi-waveform VCOs and mixer, wavetables from the actual 303, an integrated envelope generator, a powerful filter, and a pluck circuit!

Experiment with this and you'll find yourself making some of the craziest, squelchiest acid the world has ever heard!

Oh, and there's also a hidden feature - see if you can find it!

EssEff

EssEff is a SoundFont (sf2) player! Comes with a few free soundfonts and the button lets you load more.

Generators

Supersaw

Twin LFO

Also has a shape wheel for mixing the sin/saw shape, and has knobs for offset and inversion. All parameters are voltage controllable!

Noise

Range LFO

FX

Bit Crusher

It's a bit crusher! Accepts control voltage, and sets a (voltage controlled) minimum bit depth for fine tuning.

Filter Delay

Sidechain

Widener

Stutter

Filters

Filter

Filters

Notch

KTF

Numerical

Integers

Floats

Randoms

Generates three random values. The range of the values can be controlled via CV, but will default to (-12, +12) if CV values are empty/equal.

Mixers

Left Right Mixer

Mono

Volumes

Panner

Panners

Musical

uQuant

uQuant is a very skinny micro quantizer. Includes key, scale, octave, transpose, trigger and output.

uQuant is really just a bastard skin of Scale Quantizer mkII by AmalgamatedHarmonics - so all credit goes to them!

Live

BPM

You can get some weird polyrhythmic stuff by putting an LFO on the CV, which gives a variable BPM. Even weirder if you start using a bunch!

Button

Buttons

They're arranged a drum pad, so it's fun and easy to make a playable drum pad simulator by building a circuit like this:

Metaknob

ReplayKnob

Splitter

Splitters
