This video, via Marko Ettlich of RetroSound, compares the classic Oberheim OB-X (1979) 8-voice synthesizer against the Oberheim OB-Xa (1981) 8-voice analog synthesizer:
In the video, Ettlich compares the two keyboards, using ‘identical’ patches. Here’s what he has to say about the video:
This video shows the different sound character.
The OB-X is discrete analog like the SEM modul and sounds very raw and wild.
The OB-Xa based on Curtis CEM ICs and sounds more smooth.
Both are great synths and I love both a lot. The king class of polyphonic analog synthesizers.
Have you used either of the Oberheims? If so, leave a comment and share your thoughts on them!
