Eventually, I ran out of room in the 48u original case and had to expand. I went with a 60hp wide rack, two 3u rows with a mini 1u tile row in the middle. Surely, I will never outgrow this!

The second version was mostly a superset of the original, and includes many of our old favorites like:

• Arduino SD Card Sampler
• Trinket 3-octave quantizer
• Passive Mult
• I AM O vactrol VCA
• MS20 VCF
• VCO 3340
• 4-channel mixer / amp / attenuverter

This also made room for an explosion of new modules in oh let's say 2018. These are yet to be documented, and include:

• The CMOS Clock Divider
• Arduino-powered Turing Machine Light
• 4-channel audio taper VCA
• 2-channel linear VCA
• Passive 8-channel attenuator
• Spring Reverb Driver + Chamber
• ItsyBitsy Clouds
