Eardrill Periodicity and ModuleModule Buchla

"Periodicity
The Buchla 281(e) quad function generators are the unsung heroes of the Buchla Electric Music Box. They perform all sorts of transient and cyclic duties. They are among my most-touched modules. That said, I still feel the need for some dedicated LFOs."

"ModuleModule
Buchla cabinets represent some expensive module real estate. There have been a bunch of little utility functions that I have wanted from time to time in my Buchla system, but gathering just the right combination of functions into a universally loved utility module seemed virtually impossible.
My solution? The ModuleModule

The ModuleModule is a normal Buchla-format module that implements a frame that can hold up to four "standard" mini-modules; "ModuleModule modules", if you will."
