"Great cosmetic and perfect working condition this oberheim ob-xa synth has been professionally fitted with a real world interfaces midi interface which handles midi in and out, channel and splitmode data. Channels selected by the keyboard keys. The synth is a kult analogue polysynth with 8 voices and 16 oscillators.

Its a very powerful instrument sonically and with midi control its possible to use it as a midi controller keyboard as well as a 2 part analog sound module and it's a late model with patch memory of 120 programs or patches.

You can use double mode to double the patches and create very complex waveforms. Its a super musical synth with autotune function to keep it in tune. This synth has just been carefully restored with the keyboard completely overhauled new key bushings and lubricant. The keys realigned and j-wire triggers adjusted carefully for use as an accurate midi controller. with the RWI midi upgrade one button and switch have been added to the front panel to turn midi on and off and select modes, channels & functions as a panic button. Wood ends have some scratches but look good. Front panel some light scuffs and scratches but nothing that detracts significantly from the impressive machine."
