Akunull has introduced Piloslib, a free open-source library of audio and modulation tools that focus on synthesis, live electronic music, interconnection, probability, unique sounds and intuitive interfacing.

Piloslib has been developed by Akunull in Pure Data, starting in 2014.

Here’s what’s included 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

The synths:

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.

The 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.
Downsample-Down-sampler.
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.

Piloslib is available as a free download via Github.
