This mod allows your ElectroComp EML-101 or EML-100 to track conventional 1V/Octave control voltage from another synth, controller keyboard, or sequencer. The EMLs use between 1.2 V/Octave and 1.4 V/Octave (varying from one unit to another) with an offset of between 4.2V and 4.6V. Our mod board scales up and adds the offset to the CV you feed into the Sequencer jack (EML-101 Version 2) or a new jack installed in place of the CM3 jack (EML 100, EML-101 Version 1). Multiplexed switching turns the mod on and off without having to install an external switch.
This means that it can be completely invisible– no hole needs to be drilled, and the synth functions 100% as original when nothing is plugged in to the CV input jack.
The PCB comes with a link to schematics, bill of materials and detailed installation and tuning instructions with lots of full color photos. The kit comes with all of the above plus all required parts and the 5-terminal jack already partially wired (because this is probably the thing people are most likely to mess up!)
