Aside from the filter type and the robust sequencer/arpeggiator implementation of the ProTwo, is the sound engine from the P12 and P2 the same or nearly the same? Is owning both redundant?

Question - In the song "Change" at the 2:40 minute mark there is a synth bridge where they play what seems to be bass octaves back and forth rapidly.

Anyone ID this fat bass-oriented synth sound? Sounds Oberheim-esque but lots of synths can make this sound.

Thanks!
