Octuple VCO
Eight 555-based saw-core VCOs in 16HP. with shared control voltages and voltage-controlled detuning among the eight oscillators. Originally intended to be a published DIY project, but the completed module had enough issues with it (in particular, the VCOs synching with each other through crosstalk in quad op amp chips) that it's probably not worth publishing the design; hence, the prototype is one-of-a-kind. Some of the ideas will be reused in future projects.

These merchants probably sell this module. Huh?
