There are 5 pages of pictures and information about this perfectly preserved E-mu Modular.

This E-mu Modular is being put up for sale by Mad Science Lab and Silicon Breakdown on behalf of the original owner Mr. Cooper.

All pictures on these 5 pages are of the E-mu Modular for sale. The unit is 100% functional. It was serviced by Riley Smith who spent more then 20 years at E-mu and was one of the technicians who repaired E-mu Modular Systems. He also worked for Sequential Circuits before working for E-mu. Riley had the unit for 3 weeks and was able to fully test and, calibrate the E-mu Modular, and check every function. He said the oscillators were still almost perfectly in tune, but he tweaked them even closer using a frequency counter.. The pots are noise free and all the jacks and options work as intended. He also replaced all the rubber bushings on the keyboard and refurbished it to play like new.

All the oscillators have been calibrated and sound great (see the sounds page)

This Modular was hand delivered new to Mr. Cooper in 1980 by Scott Wedge, one of the founders of E-mu, who flew out with the unit to Massachusetts. It has been safely stored by Mr. Cooper at his house until it was returned back to Santa Cruz County to Mad Science Lab in April of 2017 for calibration and documentation. Mad Science Lab is the studio for Silicon Breakdown and is run by myself, James Gideon. I spent 10 years working at E-mu so I have a real soft spot for E-mu Modulars. I agreed to sell this synth for Mr. Cooper if I could document it fully, and have some time to make my own sounds.

This E-mu Modular System can be thought of a three separate analog synthesizers.

On each row you will find a Keyboard driven VCO, one VCF or more, a VCA, and extra goodies. There are also four envelopes which means there is an extra envelope for modulation. Combine all three into the 4 input stereo mixer and stereo reverb module to make massive sounds.

What is convenient about the E-mu Modular is that you can select Keyboard 1 to drive the modules with a switch on the module itself, so pre wired patching for basic keyboard CV and Gate control. Even the 3 Low Pass Filters have switches for keyboard control.

Adding a MIDI to CV connected to Keyboard 2 you can switch between MIDI control or the keyboard control by just switching the switches on each oscillator and Envelope.
