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).

Fibo v1 for Pd
[fibo] v1 (2017) generates a fibonacci sequence through recursion for a list of n numbers. Useful for driving metronomes to create rhythms.
Factorial v1 for Pd
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)
Forthcoming: v1.3 will have one binary for all and a decagonal decoder for Berklee’s EPD program.
– Encoders for 1st, 2nd, and 3rd order ambisonic panning
– Based on Furse-Malham (“FuMa”) coefficients
– Decoders for stereo, quad, 5, 6, and 8-channel loudspeaker arrays
– Soundfield manipulations: tilt, rotate, tumble, rotilt

Lerdahl v1 for Pd
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.
