Hi all,

Before there were plans for several bbd-modules, but it sounds like
there will be only one big fat extremely cool 'universal' bbd module
now Great news!

Just one remark: personally I wouldn't mind an additional bbd
module that's optimized for solid sound at delay times around 500
ms or longer, but just as an extra, you know... ;-)
