Synapse Audio has mixed up the juices and formulated a deep emulation of the classic Oberheim OB-Xa polyphonic analogue synthesizer.
Obsession
“Obsession” is probably the right word to describe the synth communities relationship with the Oberheim OB-Xa. There are many promised hardware replicas and a recent rash of software emulations. The latest is from Synapse Audio and claims to be a “Very deep, realistic emulation of an analog polyphonic synth”.

Obsession is analog modelling. It uses models of oscillators, filters and VCAs to recreate this classic synthesizer in very fine detail. It then combines it with shed loads of control and modes of modulation.
Each voice has 2 oscillators, a 2 pole/4 pole filter, 2 envelopes and 2 LFOs. Obsession has some individual voice control which allows for variation between individual polyphonic notes offsetting filter cutoffs and amplifier settings as well as the sort of scaling that was found in the original hardware.
The back panel gives access to a large modulation matrix, definable stepped LFOs and a bunch of useful effects for building that huge analog polyphonic sound we do so enjoy.

It looks perfect and sounds fantastic. We are spoiled for choice for software OB-Xas at the moment. You can download a working tester of Obsession for Mac and PC and see if it smells like you hope it will. To keep it will cost £79.
