One of the big attractions at the 2014 NAMM show was the Moog Sub 37 Tribute. The Sub 37 Tribute includes updated features including Duo Mode, which allows oscillator 1 and oscillator 2 to be played independantly, programmable arpeggiator/step sequencer, two modulation busses with assignable source and destination options, access to 256 presets, and a 37-note velocity sensitive keyboard with aftertouch.

A fully featured mixer section contains dedicated controls and mutes for each sound source, as well as a level control for External audio input and Feedback - which feeds the output of the filter directly back to the input of the mixer. Also included are the powerful DAHDSR envelopes from the Sub Phatty with panel control of each extended function. And, like the Sub Phatty, the Sub 37 Tribute includes a free standalone/plugin editor that is compatible with all major plugin formats - creating seamless integration between analog synth and DAW for total control, recall, and automation of every parameter
