Tom Oberheim has reissued his very first analog synth-- the Synthesizer Expander Module (SEM). This new SEM module is pretty much the same as the original, that is to say 100% analog! True voltage controlled oscillators, the classic SEM multi-mode filter, analog VCA, analog envelope generators and LFO. In fact, he made the circuitry as close to the original as possible.
All internal SEM connections are brought out to 3.5mm minijacks - all 33 of them. The basic connections are a one-volt-per-octave VCO control voltage and a standard 0 to +5 volt gate signal. On this version of the SEM, there is no MIDI input.
In addition the basic SEM module with no case, power supply or supplemental module is available specifically for drop-in replacement for an original SEM in older Oberheim polyphonic systems. (special order)
