looking for a variable step size sequencer vst , mark fell style.

[xoal]

a step sequencer with individual length per step, anyone?
As well as repetions and de/increments per step and some randomness.
like mark does it.

there are lots of m4l devices or pd/max patches that implement certain aspects of it, and I even saw mark giving a lecture about his approach recently but simply not a max msp user atm so..

any hints are appreciated!

similar to this, which is actually build by him and his son (online sequencer):
