"Now isn't this cute? Well it may look cute, but it sounds just like its big brother the OBXa, because it has the same voice cards. This is a 6 voice model with 56 presets, and it was upgraded with a MIDI in and thru port. This mod was done before I obtained the unit, so I don't know how extensive the MIDI implementation is, but I'm betting its just a basic note on/off system. I have tested it by controlling the unit from another controller and it works just fine. All voices, keys, knobs, and switches work correctly.This unit also has CV gate in/outs. This unit is in very good condition cosmetically with a few very small scuffs here and there. For those unaware, this model was designed to be the less expensive baby brother to the OBXa. It is not programmable. You can however tweak all of the most commonly used parameters such as the filter, envelope, octave transpose, portamento, vibrato, pitch bend, etc in real time, you just can't save the changes. There are 56 presets in memory, most of which are actually really good the way they are (I think they are original OBX/OBXa presets), but are jumping off points for tweaking them however you like using the front panel controls..."
