# Sequential Circuits Pro One
“SEQUENTIAL CIRCUITS – PRO-ONE — ANALOG SYNTHESIZER — WITH MTG PRO-ONE REPLACEMENT CPU CHIP – (http://www.musictechnologiesgroup.com/ ) —– IN EXCELLENT CONDITION!! 100% FUNCTIONAL!!! Some marks and scratches on wood end pieces. Keys and face looks great! Some scratches on the bottom and it looks like the previous owner tried to cover it up with some black marker pen, not a big deal, you will not be looking at the bottom when you are playing it. The power cord has some electric tape on it, so I am assuming that there might be some tears in the power cord sheath, but not a problem, powers fine and doesn’t effect the functionality. Sounds just like a Prophet 5 Rev. 3 , same CEM chips in both, so simply amazing!!!! The CPU upgrade adds more sequencer memory, more arpeggiator functions and the ability to add MIDI very easily, if you ever decide to add MIDI to the PRO-ONE. The Original CPU chip is included, it is functional. — Selling due to the fact that I need the money.” Link
