Subsequent 25 is a 2-note paraphonic analog synthesizer that melds the hands-on analog soul of classic Moog instruments with the convenience and workflow of a modern sound-design machine. Moog’s most compact keyboard synthesizer, the Subsequent 25 delivers all of the rich sonic density that Moog synthesizers are known for.
The Subsequent 25 features a silky keybed with enhanced playability, a high-powered headphone amplifier for live monitoring, and analog signal path embellishments that significantly expand your sonic palette. From behemoth basses to lashing leads to posh pads, the Subsequent 25 is a serious performers’ synthesizer with the hands-on control you need to inject serious expression into your live keyboard performances. All in, the Subsequent 25 is an irresistible analog synth value with classic fat and punchy Moog sound, real-time tweakability, and a lovely, custom chassis with wooden side panels, lovingly handcrafted in Asheville, NC.
Along with the flexibility of CV (Control Voltage) and audio inputs, the Subsequent 25 also gives you an enhanced analog signal path for a broader palette of sounds. The re-tuned Multidrive circuit lets you crank the gain further for a more extreme range of dirt that can blast through a track more aggressively than the relatively polite growl and grit on tap in the Sub Phatty. The Subsequent 25 mixer also has double the headroom for access to a new range of classic clean tones, and the Ladder Filter gain staging has been massaged to boost harmonic saturation and signal compression for in-your-face bass that will blow holes in walls.
We have received quite a few questions at Sweetwater about Moog’s Duo Mode — an architecture shared by the Subsequent 25. This is basically a two-note paraphonic mode; meaning each of the two oscillators can play a different note while sharing the same audio path. You can hold a bass drone note while playing a lead over it, play in intervals, and create other interesting musical textures and effects you can’t achieve with a monophonic synthesizer.
