My Oberheim OB-1 was recently serviced by This Old Synth in San Jose, CA. This video is just running through some of the features, including cross-modulation, presets, 12/24 dB/oct filter, modulation sources, sub-oscillators, pulse width modulation, and a few other things.
I found this OB-1 at a shop in Portland, OR, and it had a number of issues. This Old Synth straightened it all out (figuratively and literally) and now she plays like new.
The OB-1 is a cool piece of synthesizer history. It's a monophonic programmable analog synthesizer with two oscillators, each switchable between sawtooth and pulse waveforms, and each with an independent sub-oscillator. Plus discrete electronics, a very early form of programmer, great-sounding 2- and 4-pole switchable filter, and a handful of unique features, all with circuitry that comes straight from the classic Oberheim SEM modules, make this monophonic analog synthesizer worthy of the Oberheim name.
