OBERHEIM Four Voice / 4 Voice SEM - Analog Synthesizer 【SYNTH DEMO】

Published on Oct 11, 2018 synth4ever

"Oberheim Four Voice analog synthesizer demo. Playing sample & hold sounds on vintage Four Voice / 4 Voice SEM analog synth from Oberheim.

The Oberheim Four Voice a 4-voice SEM polyphonic analog synthesizer from Oberheim which was released in the mid to late 1970s. The Oberheim Four Voice was Oberheim's largest synth at the time, and features discrete analog circuitry including 8 VCOs (2 per voice), LFOs, a LPF/HPF/Notch filter, 2 ADR envelopes and 49 keys.

The Oberheim 4 Voice has a huge analog sound and is essentially four monophonic Oberheim SEM synths connected together for four voices of polyphony, with each SEM unit having its own filter and envelopes. It can also be upgraded to an Oberheim Eight Voice by adding 4 additional Oberheim SEM modules.

This Oberheim Four Voice synthesizer demo was filmed at the Vintage Synthesizer Museum in Oakland, CA."
