Sine Delay v1 for Pd

[sinedelay~] v1. is a waveform generator and variable delay line external written in C for Pure Data (Pd). The external allows crossfading between waveforms and provides 4-point interpolation between tap-delay times in ms. It also has build-in amplitude modulation. v1. applies a tanh-based, soft digital distortion to the delayed output (right-most outlet).

Ambisonics Externals for Pd and Max/MSP

General Updates: Max/MSP support (port from Pd).

[grambipan~] updates: 7th order (2d) FuMa support

[grambiman~] updates: rotate-tilt-tumble support (3 axes support for b-format rotations using 3d controller, such as the HTC Vive) ordering must be rotation, tilt, and tumble.

[grambidec~] updates: hexadecagonal decoder (16 channel ring)

Lerdahl v1 for PdScreen Shot 2015-12-29 at 11.39.20 AM

[lerdahl] is an external for Pd written in C. It is largely based on ideas presented in Fred Lerdahl’s book, “Tonal Pitch Space” (2001), on the construction of melodies.

Version 1 takes any MIDI input and outputs values for pitch class, basic space, closure, tension, ratios of asymmetrical attraction, ratios of asymmetrical attraction * pitch class distance, and pitch class distance. 

The user may change the configuration of the basic space to accommodate any of the 7 modes of the major scale.

The user may also offset pitch class zero if they want zero to be something other than Middle C (C3 /4, etc.).

Mac only, for the moment. Version 2 will be cross-platform, have list outputs, and more useful construction arguments.

Pd2Live v1 for Pd

Pd2Live is a digital music performance system, built in Pure Data (extended 0.42.5), designed specifically to function with a multichannel audio output (audio per string) of an augmented electric guitar provided by bespoke audio break-out hardware. The system was designed in support of my doctoral thesis (available shortly), providing a digital performance environment from which an instrumentalist may interrogate instrumental percepts in relation to the creation of sophisticated timbral and spatial digital audio signal processes. On a fundamental level, the user may design and implement unique real-time signal processes per string of the guitar, permitting the creation of dense polyphonic instrumental musical structures. The (spectromorphological) design of each string may correspond to real-time instrumental figuration executed by the performer.
