Generators

Supersaw

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

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

Noise generates pink and white noise! It also has an integreted high pass and low pass filter. Everything is voltage controlled, and there's a bonus volume knob.

Range LFO

Range LFO is an LFO which can be explictly mapped to a specific (controllable) range. Very handy!

FX

Bit Crusher

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

Filter Delay

A modification of the basic delay that filters each feedbacking pass. Kind of reggaeish, good for pads too.

Sidechain

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

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

It's a digital glitch effect! Use the main on/off button (and related input) to turn the looper on and off, then use the time knob (controllable with CV) to adjust the size of the stutter. Also has a mix knob.

Filters

Filter

Filter is a voltage-controlled integrated high-pass and low-pass filter. Also includes a voltage-controlled res and mix paramater knobs. It's a really good VCF.

Filters

Filters is like Volumes or Panners, but for Filters. Each knob controls both a low pass and high pass filter. Super handy!

Notch

Notch is a notch filter! You can play with the frequency, depth and width. All voltage controlled.

Numerical

Integers

It generates three (voltage controlled) integers from -12 to +12!

Floats

It generates three (voltage controlled) floats from -12 to +12!

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

A simple 12-to-2 mixer for mixing multiple stereo signals. With an additional overall voume knob.

Mono

A voltage-controlled mono-izer. Given a wide dual input signal, convert to mono outputs based on a knob and CV. Has two outputs, but only one is need if you're just going to 100% mono.

Volumes

A modification of ‘Mutes’ that adds the ability to adjust the volume of 10 different input-output pairs. Can be used to quiet and amplify.

Panner

Panner is a voltage controlled panner. Without CV, it pans a mono signal into left and right channels based on the value of the knob. Combine with an LFO to build an autopanner!

Panners

Panners is a bank of 5 panners. Each takes a stereo input and a stereo output. Pretty simple but handy for placing lots of elements around a stereo space.

Live

BPM

BPM lets you set a voltage-controllable beats per minute, with an array of outputs that get a +12 signal. There is also a CV reset with a connected button.

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

It's literally just a big ass button with six outputs. You hit it, it sends a +12 reset signal.

Buttons

It's not one big button - it's lot of little butons!

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:

Utilities

Splitter

It's a 1 to 9-way splitter! You've got a signal - now send it everywhere!

Splitters

If splitting one signal to many isn't your fancy, Splitters gives you a 5:10 splitter instead! Handy!

Displays

Three digital displays. Useful for debugging. Provides a passthrough output as well.

Range

Range will map an input from one range of values to another. So, if you have an oscillator which outputs from 0/2, you can map it to a -5/5 audio signal or a -10/10 CV. Handy!

Future Plans

None of them actually exist yet, but I'm hoping this will project eventually contain:

• FFTTuner - FFT / Tuner
• VCDryWet - A simple dry/wet mixer
• DubEcho - Two delays and a spring.
• Ping Pong Delay (or maybe just a delay with seperate dry/wet outs that can feed to the panner?)
• Vocoder, maybe?
• Dedicated 808/kick circuit with click
• Reverb - It's a reverb!
• Phaser - Pssshheeeeeooooooowwwwwwoooowowwaaaaaahhhhhh
• Harmonic Saturator
• Ring Modulator
• Granulator

Building

First, clone and make Rack for yourself.

Then, clone this repo into the plugins directory and run make from this directory.
