Another Pultec-y looking thing
Posted: Mon Apr 27, 2020 9:53 am
This one's based on the rather obscure Oberheim OB-Mx, which came out after Tom had left the company and was actually a project begun by a team that had a lot of trouble, so Don Buchla (of all people) was brought in to bring it to completion.

- Two wave-mixing oscs, with separate Portamento. Each can phase modulate the other.
- Two Filters - a 4-pole LP and a 2-pole Multimode; each with it's own input mixer.
- Two pannable amps.
- Three LFOs
- Four DAHDSR EGs.
- 14-slot Mod Matrix.
The hardware was a real headache to program; the panel only had a single set of controls for most of the sections, so you could only adjust one osc at a time, one LFO at a time and one EG at a time. Here, of course, all is visible and accessible at once.
This represents one of it's 'voices', so is not 'multitimbral' like the hardware.
Personally, I thought the OB-Mx's interface was a real snoozer (except for that great logo), so it made a great candidate for 'the Pultec treatment'. The blue panel can be switched to red.
The OB's Mod Matrix is represented as a Patch Bay.
Be sure to read the info pane on the LFOs - they have some unusual controls and capabilities that show the unmistakable hand of Buchla.
