Audio Coding+Production Stream #6


Some issues with lag so it’s short, apologies. Making electronic music for a little here. Only used three instances of one type of synth, Imp, for all sounds

About these streams:
Synthesis, sound design, coding, and production using all or mostly open-source software, centered in Pure Data vanilla (piloslib)

isto_syo draft 2


Short video of a patch in progress. Source code available here. Coded and synthesized in Pure Data

Piloslib now available – multi-platform open-source library of audio and modulation tools


Piloslib is now available on Github. More info and a fully synthesized demo:



Multi-platform open-source library of audio and modulation tools that focus on synthesis, live electronic music, interconnection, probability, unique sounds, and intuitive interfacing built by Akunull in Pure Data starting in 2014.


Pure Data

Basic Pure Data
Basic electronic music concepts

Getting Started:

See intro.pd in root folder or watch the intro video. You must have the objects in plate.pd to use the library.

What is in the library:

Vanilla only patches without expr(~) editable in pd
Syntactic sugar to make Pure Data programming more efficient
Several ways to make complex rhythms and a global clock to guide it
A save and load system with preset management
A way to handle per voice modulation for synthesizers
Unique modulators for control
Tools for generative design
Model-(View)-Controller programming architecture
An assortment of synths and audio effects capable of some classic sounds and many strange ones

Ideas behind the library:

Readable, encapsulated code with intuitive interfacing and ease of use in mind
Simple code, commenting, and intro tutorial instead of help files
Portability through naming conventions and no externals


rhine-2 osc synth with 2 filters and mhx modulation system
sentinel-2 osc synth with variable pole lp/bp filter and mhx modulation system
imp-2 osc synth with a lot of linkage to exponential envelopes and mqu modulation system. Built around synthesizing drums
ajah-3 osc synth with fm interconnection between them and mhx modulation system
osciano-Simplest synth, one oscillator
nbd-Simple bass drum synth
rhibd-Simple bass drum synth with complex per voice modulation (mhx)
rewbd-Bass drum synth with more saturation options
ncym-Simple cymbal synth
nhh-Simple hi-hat synth
nsn-Simple snare synth

Audio Effects:

asym_tanh-Asymmetry and tanh(x) for non-linear compression, distortion, tape-like saturation
bellmid_3band-3 band eq with tanh(x) (non-linear compressor) with the middle channel also including the low and high
eq_3band-3 band eq
eq_3band_tanh-3 band eq with tanh(x) (non-linear compressor) on each band
bit_red-Bit reduction
bp_mix-bandpass filter with dry/wet mixing controls
lop_mix-lowpass filter with dry/wet mixing controls
hip_mix-hipass filter with dry/wet mixing controls
vcf_mix-bandpass filter with dry/wet mixing controls
vcf_np-vcf (bandpass filter) with variable amount of poles
vcf_npnp-vcf~ (“voltage controlled” filter) with variable amount of poles and variable “low-pass” or band-pass
formant_filter-Formant (vowel) filter with 5 formants
formant_filter_3v-Formant (vowel) filter with 3 formants
delay_extfb-Delay with external feedback so you can customize the delay line
delay_ms-Simple delay
delay_ms_pitch-Simple delay with pitch shifting in the feedback loop
pitch_shift-Pitch shift via phase vocoding
retrig-Retrigger/stutter/buffer/beat repeat
retrig_ij-Retrigger with multiple rates inspired by Instajungle
tanhx-Tanh(x), a non-linear compressor capable of emulating a lot of saturation and distortion
vverb-Reverb via freeverb algorithm
