ROLAND SYSTEM 100 MODEL 101 + TOM OBERHEIM SEM PRO ~ Will They Pair? Ep.31

Published on Sep 15, 2017 once upon a synth

"Pairing the Roland System 100 Model 101 with the Tom Oberheim SEM Pro. The Roland Model 101 is the keyboard synth part of the System 100 series which was a system of synths made by Roland in the 70s. The Tom Oberheim SEM Pro is a reissue of the classic Synthesizer Expander Module (SEM) which he made in the 70s to expand existing modular synths at the time.

Together these pair quite nicely because they both sound amazing and they're both semi-modular. This means that they both expose patch points so you can access different components like the oscillator and filter.

In this video I take advantage of the external audio input of the Model 101 to add a second oscillator via the SEM. This is easy because the SEM exposes both of its oscillators via the patch panel. So all you have to do is patch the keyboard CV from the model 101 into the CV control of one of the oscillators on the SEM. Then, you simply patch the output of the waveform you want into the external input on the Model 101.

I also go through different types of patching in the video like replacing the envelope generator of the 101 with the SEM's envelope."
