The files contained in this repository are experiments for generating electronic music in Pure Data (Pd).

Pd-extended is not used for this repo, so some of these patches might be a little bit over the top when Pd-extended might offer similar capability in an easier format.

Directories would be nice, but Pure Data requires each path to be a single directory and does not dive into subdirectories. This repository is meant to be used as a single search path for Pure Data, mostly because that is easier than adding a bunch of paths to subdirectories as needed or desired.

Some of the typical modulators. AM, FM, etc.

Shows how to use AMmod~. Two AMmod~s are used to show daisy chaining the modulation, and some buttons exist for interesting settings.

• uses
• AMmod~
• fullphasor~

Modulates the left carrier signal by the right modulator signal. Carrier and modulator signal are both expected to be full amplitude -1..1.

This set of patches is inspired by the custom wave chapter in the FLOSS Pure Data manual.

There seems to be a superfluous warning about 0-custom-wave-shape: no such object. This is due to the use of $0 in an array, but the array and pd commands all function as expected.

Shows how to use wavegenerator~. Two wavegenerator~s are used to show independence between the abstractions (related to notes about $0 above).

One has a bunch of sliders to configure it, the other has two options submit by way of messages.

• uses
• wavegenerator~

Creates custom waveforms by specifying a bit resolution for the wave, a base frequency to play the wave at, and some sinesum parameters to shape the wave.

• uses
• handle8args
• hardbounds
• todo
• condense sinesum parameters into single inlet via pack/list?

Constrains a value between a minimum and maximum value. It's helpful for abstractions where user controls might be configured externally, because the controls might not respect the proper value extents expected by the abstraction.

If the test value goes below the minimum value, the minimum value is output instead. If the test value goes above the maximum value, the maximum value is output instead.

• todo
• use handle3args

As a programmer, I see each block as a function with inputs and outputs. There are three ways to push input arguments into these functions:

1. inlets
2. a list of arguments in the object box
3. a list-message to the first inlet

I wanted to make an abstraction which would handle all three cases in the same way. Wire up your inlets directly to an abstraction and then wire up the outlets of the abstraction as if they were the inlets.

Demonstrates how handle3args works. Shows many ways to connect to the handle3arg's inlets, with simple output of the outlets.

• uses
• handle3args

Strongly commented argument handler. Supports 3 arguments by way of 3 inlets, object-level arguments, and/or a list of 3 passed to the first inlet.

Unfortunately, I have not figured out how to generalize this solution to support an arbitrary number of inlets/outlets from a single abstraction. Each number of arguments will need its own abstractions. Whichever abstractions are present are because they were needed.

If you don't feel like making your own but there is one with more arguments than you need, use the abstraction with more arguments. Just ignore the extra inlets/outlets.

The idea is to use simple, familiar wave functions which are produced at randomly sampled frequencies.

This is not yet advanced enough to do 1/f noise or that sort of thing.

Shows an example of hooking up to noisegenerator~.

• uses
• radio2symbol4noisegen
• noisegenerator~
• stereomixer~

Converts floats into symbols of off, sine, square, saw. Auxiliary.

Generates one of three wave types at a specified frequency.

Changing the frequency can be performed by an internal oscillator or external bang.

• uses
• fullphasor~
• square~
• [lnrnd4Hz|unifrnd4Hz]

Randomly samples floats from a distribution close to the log normal distribution.

The extent of the floats are meant to be interpreted as Hz within human hearing capability. These might need to be opened up for younger persons with higher frequency reception or with better performing speakers.

Randomly samples floats from the uniform distribution.

The extent of the floats are meant to be interpreted as Hz within human hearing capability. These might need to be opened up for younger persons with higher frequency reception or with better performing speakers.

Miscellaneous tools.

Tests the crossfader by alternating between two stereo tones.

• uses
• stereocrossfader~

Takes in two stereo inputs and crossfades between them. Left two inlets are deck A channels, next two inlets are deck B channels, and the right most inlet is a ratio of B from 0..1.

0 will output only deck A's channels, 0.5 will evenly mix decks A and B, and 1 will output only deck B's channels.

• uses
• hardbounds

Modifies a fullphasor into a binary square wave.

Extends phasor amplitude from 0 to 1 to -1 to 1, for audio saw waves.

Inputs a master gain for both channels, 2 audio channels, and independent gain for each channel.

Inside the abstraction, volume meters display each channel's dB and waveforms can be visualized with an oscilloscope-like function.

• todo
• try to overlay independent gain control floats into the audio inlets
• use hardbounds

A sine function to complement the cos~ cosine function.
