I've run out of room in my little music corner. So I've decided to make 
some Eurorack modules using mostly surface mount components. First up 
are a Sequencer, a Fixed Filter bank, and a useful mixer.

The 50HP wide sequencer is a Moog 960 type thing but with parallel stage 
loading like the expanded Turing Machine and Klee:


The 8HP wide fixed filter bank is based on my own human voice module 
which was first released as a half rack project and then a 5U module 
some time ago. Those modules were originally based on the human voice 
presets of the VP-330. This time I've given each of the seven band pass 
filters its own level pot.


The little 6HP wide mixer is based around the original 'Stooge' variant 
of the 5U Oakley Multimix. I decided to do away with the original's 
reversible attenuators and go with a pot and inverting switch instead. 
This just seems more practical when the module is this teeny.


PCBs are available right now. Documentation is already available but 
I'll be adding more details on the construction side of things to the 
Builder's Guides over the next week or so.

I hope to port most of my 5U modules into Eurorack over the next year or 
two. As well as some newer ideas I want to build.
