By far the most prevalent of the original Prophet 10 models, the Prophet 10 Rev3 is a better built version than the previous iterations for more consistent and reliable performance. It differs from the previous models by utilizing Curtis Electronics Manufacturing chips. It features 2 VCOs per voice, a low pass resonant filter with ADSR, LFO, & cv/gate controls. For a more affordable, modern version of this synth, Sequential has released the Prophet 10.
