Or2v is an emulation of the Oberheim 2 Voice, a duophonic synth which has a SEM module per voice, each having 2 VCO, 1 filter, 2 envelopes, 1 noise generator, 1 Lfo, pan, Sample and Hold, portamento etc. 1 echo added... There is also (and this is its main interest) a 8 step sequencer with several destinations. The spirit of the original machine is kept and gives something rather fascinating, like the ability to play a solo with one module, while a sequence runs on the other one. An original and very nice synth.
