No sir, these modules are NOT 1V/oct but they're close to it. I think the VCOs are more like 1v/11 notes. 
 Its something I've thought about a lot. These circuits are somewhere in between the new style of modular noise "lunetta" synths and traditional modulars. I've sacrificed many standardization and response characteristics in favor of compactness, low cost and quantity of modules per board. For instance I never could have fit 4 VCOs on one small board like that if I included 1v/oct and other features found in traditional musical VCOs. That said if the demand is there (which i suspect it is) i will probably design a precision VCO board for this series that holds 1 or 2 high quality VCOs.
