i have been building sequencers with markov chain use bang to trigger samplers synths ,how can i create drum rolls
one bang triggering repeaters in 16 32 or what ever.
have looked at uzi module doesn't do much the way i'd like

[uzi] and [kalashnikov] both emit bangs as fast as possible (effectively instantly).

A naive but interesting way to do things is to use [del] chains. A cascade of [del] with each feeding the next can be given a common delay parameter that corresponds to some factor of the tempo period like 1/32 beat.

Better ways are to use counters driven by a master clock running at some multiple of the usual timebase.

thanks obi just another thing when i reload my patch all the numbers and horisontal sliders are at zero is there a basic way to store presets ?

Yes, set the slider properties to INIT and they will hold (and send out) the last value each time the patch is saved and loaded again. Ordinary number boxes don't have this property, but type2 number boxes do, so replace them and it should work.
