The first four modules have been completed. They are as follows-

-6x 40106 oscillators- three of them use .47uf caps and the other three use 10uf caps. 

-6x 40106 inverters

-1 4040 divider

-1 4051 multiplexer

these modules are mounted in one PVC panel measuring 4"x11" and will be mounted in a case when the project is done.

The next panel will have two 6bit R2R DAC and three FM oscillators with CV in for pitch, FM and mod on/off as well as two pots to control pitch and modulation range,
