so, here it is :
the Rhombusine ( for non English users , rhombus is the name of this form <> )
you'll need the last 1.2 matrix pack for this one

A minimal rhombus sequencer , with 2 sequences ( 19 and 27 steps ( i know ....not usual..) ) , 2 directions for each one , and a random function for the steps , central cell is the play button..
Here a little schematic of his minimals functions

if you want to use it with an other vsti , just delete the heliosII inside the patch and use a midi bus named vsti
This add-on is also a door to monome like patch , where some cells can be used as function and more...
This addon has nothing new in the concept but i have always think that when we change our practices , it wake up our creativity..
