Tom Oberheim SEM Pro

Selling my Oberheim SEM Pro to buy myself a poly synth instead. Almost never been used. Works like a charm. Signed by the creator, Tom Oberheim. Midi. CV patch bay. Sounds great. Quite rare.

A living peace of synthesizer history, that is what the Tom Oberheim SEM-PRO is all about. Made and signed by the legendary manufacturer himself.

SEM with MIDI to CV Converter and integrated Patchpanel. This version combines the features of the MIDI to CV version (see below) with a 21-jack patchpanel and is personally autographed by Tom Oberheim.

Select MIDI channel, controller number and bend range

Select note assignment modes: latest, high note and low note priorities

Select note re-trigger, filter track, LFO reset

A second independent control bus allows velocity, controller data, or channel pressure to modulate either or both VCOs, the filter and the VCA

Transpose function allows different keyboard controllers to utilize the complete MIDI note range

Analog portamento

Input preamp gain control - allows an external audio input to be processed thru the SEM

High precision A-440 Hz tune signal

Control voltages and gate are bought out to rear panel connectors so MIDI to CV function can be used with other CV/Gate gear.
