New VST recreation of the famous Oberheim™ SEM module
WOK has announced SAM, a VST recreation of the famous Oberheim™ SEM module.
While the soundwise construction is similar to the hardware unit, some limitations have been eliminated in the software version; so there is polyphony, a second LFO, a noise source and PWM for the saw waveform.
Special attention was given to recreate the analog variably of seperate hardware circuits for the audio paths in polyphonic mode.
SAM will be available end of August as a VST plugin for Windows with an introductory offer.

Background info:
The SEM was Oberheim’s first official analog synthesizer. SEM stands for Synthesizer Expander Module. It was conceived with the notion of being used as a backup synth connected to a sequencer for layering or beefing up your existing monophonic analog synths. The SEM itself was a keyboard-less module with two analog oscillators, a 2-pole multimode filter, ADR envelopes, and an LFO. Each of the two oscillators offer triangle or rectangular waveforms. But unlike the Moog and ARP counterparts of the time, the SEM’s 2-pole (12dB/oct) filter was a little thin. The others used a 4-pole (24dB/oct) filter which has a steeper roll-off and so it sounds much better. But the SEM’s filter offered many modes in addition to low-pass, including high-pass, band-pass and band-reject.
