temporization

Hi all,

i must manage a lot of bangs which are banging at irregular pace.
i would like to be able to output those bangs , for istance, at a pace of 40 msec.
If in 40 msec two different bangs arrive at different pace, it should then output two bangs at once, once arrived at 40 msec; if one arrive at 45 msec, it shuould be output at 80 msec. and so on.
I tried with onebang and bucket, but i got the feeling i was just complicating simple stuff... and then i got stuck! Any ideas?
thanks!
