[sdiy] reverb mad from multiple delays

[mark verbos]

Hi there,


I recently built a digital delay based on the Buchla 288. It has 8  
equally spaced delays, with individual outputs and sliders on the  
front panel. Some of the sounds I can get from this got me thinking  
about hardware reverb. I know that there was the 3011 BBD that was  
used to make reverb, but I think it could be done much better with  
digital techniques (of course I mean hardware digital, not the  
sensible DSP/micro solution ;). There was a guy from Chile who did  
something like this with 6 PT2399 chips and it sounded pretty good.  
I'd like to do something like that, but with control over everything.

Does anyone have experience doing this and/or have documents from the  
old studio units that did it? I'm thinking it would help immensely to  
see schematics for the EMT 250, Eventide SP2016, AMS RMX and whatever  
other reverb units were being made before everything went software...
