bucket brigade was Re: EH 16sec.DDL reissue?

["Lance Chance" <lrc8918@louisiana.edu>]

what is the name of the thread where you discuss the "bucket brigade" chip?
this reading samples and endless memory thing is something that i have been
trying to get to for months.  the repeater "reads samples", right? and 
that,
ultimately is why there is a pop at the loop point on a looped sine, right?

finally seeing the light,
lance
