New Stuff!

Gluten Free

<img src="https://i.imgur.com/mah5XUi.png" width="25%">

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

<img src="https://i.imgur.com/ik0hlxq.png" width="50%">

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

<img src="https://i.imgur.com/dBThKyJ.png" width="10%">

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

<img src="https://i.imgur.com/EMYzw9B.png" width="25%">

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

<img src='https://i.imgur.com/gaiWFMh.png' width="8%">

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

<img src='https://i.imgur.com/Z4F4fr3.png' width="8%">

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]

<img src='https://i.imgur.com/HoEumI7.png' width="50%" />

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

<img src="https://i.imgur.com/ceIn1c8.png" width="25%">

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

<img src="https://i.imgur.com/9RxOChc.png" width="25%">

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

<img src="https://i.imgur.com/0dudvPA.png" width="25%"> Turns a note into a chord. Octave and position controls.

MutateSeq / Notes / Sequential

<img src="https://i.imgur.com/PFUjLNd.png" width="50%"> A suite of sequencing tools.

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

<img src="https://i.imgur.com/eA37XuY.png" width="25%"> It's a brick wall limiter! Includes a pre- and post- amplifier. Sounds awesome for making heavy kicks, or throw it on before master output to protect your ears a bit. Stomp.

Dry // Wet

<img src="https://i.imgur.com/bfjukeC.png" width="25%"> Dual voltage controlled dry-wet knobs! For building effects chains.

Triggerswitch

<img src="https://i.imgur.com/jMRhepg.png" width="25%"> Dual gate-and-button-based switch. Good for building 'sections'.

Synths

ACID

<img src='https://i.imgur.com/zJyg3A9.png' width="50%" />

"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

<img src='https://i.imgur.com/ACIUKI0.png' width="25%" /> It's a supersaw! Frequency, detune and mix are all voltage controlled, and there's switches for phase, inversion and 2/3 OSC. There's also a reset button.

Twin LFO

<img src="https://i.imgur.com/dsEUqse.png" width="50%" /> Two oscillators, one output! This thing generates crazy wubs - it's super fun! The first LFO is the "main" LFO output, the second one controls the rate of the first. Set the first one higher than the second to get crazy wub effects.

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

Noise

<img src="https://i.imgur.com/l9yj0jt.png" width="25%"> Noise generates pink and white noise! It also has an integrated high pass and low pass filter. Everything is voltage controlled, and there's a bonus volume knob.

Range LFO

<img src="https://i.imgur.com/wtTzimg.png" width="50%" /> Range LFO is an LFO which can be explicitly mapped to a specific (controllable) range. Very handy!

FX

Bit Crusher

<img src='https://i.imgur.com/tjKYMUn.png' width="50%" />

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

Filter Delay

<img src="https://i.imgur.com/9CPtg6R.png" width="25%" /> A modification of the basic delay that filters each feedbacking pass. Kind of reggaeish, good for pads too.

Sidechain

<img src="https://i.imgur.com/3bQONmT.png" width="25%"> Based on a trigger signal, lower the volume of the input/output signal. CV controllable decay and ratio. Use a kick or a button to make some awesome wooshy noises or hard-knocking beats! I think there's a bug in this module but it works pretty good for me anyway.

Widener

<img src="https://i.imgur.com/KL50fgV.png" width="25%" /> Widener is a CV-controlled Haas-effect stereo widener with integrated high pass/low pass filter and a mix knob. Really useful for adding motion to a lead or for making drums rumble!

Stutter
