You will need to power it up, and then supply it with
a gate and CV. A good place to start is a Midi to CV
converter. You can get them off of Ebay around $75.

The problem will be the power supply, you will likely
need +/- 12V and +/-5V and others perhaps.

The other problem is that you need to provide voltages
for all of the envelopes, VCF filter and res...

Finally, you need to build an final output stage for
overall volume control.

In short, it can be done, but it won't be easy. Not a
simple project. Get a schematic first. Good luck.
