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 ----- Original Message ----- From: "Matthias Grob" <matthias@grob.org> To: <Loopers-Delight@loopers-delight.com> Sent: Friday, January 17, 2003 10:42 AM Subject: Re: EH 16sec.DDL reissue? > > The EDP and Repeater have great power, > >but are different things and most useful for those who enjoy twisting > >and control of multiple loops (and like reading manuals). > > no, I did not build the EDP for this and dont use it like that, >personally > > > The 16-second > >DDL is just hands-on immense fun. > > and the EDP isnt? > It has more functions, but there is no need to use them. > > Reasons for a reissue of the EH: > - cheaper / smaller than a EDP - as other units on the market are. > > - the specific sound characteristic, given by the Bucket-Brigade > technology - but thats the chip which is not available any more! > Also, this sound probably can be reasonably well moduled, I dont how > how good the DL4 is at that. > > - The speed/pitch variation as well discussed in other posts > You dont need a Bucket-Brigade for that, as it works very similarely > on the early digital delays which used pure HW AD and DA converters > that can be clocked just like the Bucket-Brigade.
