DUBER
Many years ago Peter Blasser designed a highly resonant dual state variable filter called "Dubernator" or "Duber" for processing sounds he was making at the time with his other creations like Fourses and Fyrall.
The Duber is an incredible filter, and after making boards for it for stand alone DIY builds, I decided to turn it into a Eurorack Module.

Here is DUBER with credit due to Peter Blasser for the original schematic that is hosted on ciat-lonbarde.net

 DUAL MOBVRT: An overlooked ciat-lonbarde Utility -  MOBVRT was born from the want and desire to have full control over the signals being used to modulate CV and FM inputs on ciat-lonbarde instruments. It was first concepted in 2024 and was made in tandem with the SCROLLFO (Scrolling LFO) circuit that was based on the original scroll circuit from Peter's earlier Sid/Tet-rassi/razzi Instruments, but expanded upon.  Eventually it became part of SLM. - - - - - - - - - - - MIDO OFFSET, BOOST, & ATTENUVERT - - - - - - - - - - - SLM and Dual MOBVRT (Prototype) The Dual MOBVRT Prototype was hand-etched and hand-built. The case construction is simple foam sheets, stacked and glued, then cut with a razor blade. Using this material makes for fast prototyping of cases.  The plan for now is to make the Dual MOBVRT cases the same as the original SLM cases. SLM was not very affordable, and many did not seem too... enthusiastic.. about the cost. This prompted me to create anoth...
