jtol is a max library for nested tree data structures, complex discrete pattern generation that can be applied to architectural design, music, dance; everything requiring constructed evolution in space and time. In other words, it is mostly made for designing rhythms and evolutionary patterns.

grasshopper components

Grasshopper is a plugin for rhinoceros. Rhino is a nurb-based 3d modeling tool commonly used for computational design and architecture. The following components are very simple but still useful.


divisorplot on3dpoints from divisors
numberspiral on3dpoints from both cartesian and polar number spiral
primegenerator generate prime numbers



psola analysis

psolabatch is a little batch tool for analysis used in psola synthesis (pitch-synchronous overlap-add)




microtuna is a little tool for micro-tuning with the native instrument kontakt sampler.



vst plugins

These VSTs are now probably obsolete. They used to be running on Mac OS 10.4. They have never been tested since. You need to install cycling74’s pluggo runtime before using them.
