Officially, we have not heard from Sequential, but Gearnews discovered the leak on the gear4music website: The new Pro 3 hybrid synthesizer.
This is what is known about specifications: 3 oscillators, 3 filters and 3 LFOs, digital effects and a 16-track sequencer.
Maybe Sequential is considering bringing the news out earlier because of this leak, or we are waiting for the NAMM to start.
