Moog Voyager OS WITH slew rate mod and I will include the original parts if you wish to revert it. The volume pot will occasionally cracked when turning (which Moog told me is normal and can be fixed by turning the pot repeatedly). Oscillators were tuned recently as well. I will also include a Midivolts Desktop and the Kenton CV to MIDI box which will allow you to interface with anything MIDI related. Note that you will need to scale CV going into the Voyager as it doesn't track at 1v/oct (this is from the manual and not a unit-specific issue)
