The Moog Subsequent 25 is a new compact analog synthesizer that builds on the success of the award-winning Sub Phatty by implementing the ultra-popular paraphonic functionality of Duo Mode, upgrading to wood side pieces, and featuring the already-beloved Subsequent series improvements: twice the headroom, reshaped gain staging in the Ladder Filter to boost harmonic saturation and analog compression, resulting in an overall richer low end, re-tuned Multidrive circuit, upgraded keybed for improved playability, new high-powered headphone amplifier and a free Editor/Librarian software.
