Monophonic Analog Synthesizer

The Moog Subsequent 25 is a monophonic or duophonic playable analog keyboard synthesizer with 25 keys, positioned sonically closer to the Subsequent 37 while combining the clear control panel of the Sub Phatty.

A Classic Moog

Two analog oscillators with blendable waveforms and the characteristic and popular “Moog Growl,” including hard sync, a sub-oscillator, and a noise generator, form the core of the Moog Subsequent 25. The first sound-shaping instance in this synthesizer is the mixer, which adds harmonic distortion starting from the midpoint, thus modifying the waveforms accordingly. The equally analog low-pass filter (transistor ladder) can be switched between 6, 12, 18, and 24 dB and features its own distortion parameter, allowing for a wide range of sound alteration from subtle to aggressive. Two snappy ADSR envelopes of the Subsequent 25 are permanently assigned to the filter and VCA.

Play Me!

The almost self-explanatory control concept of the Moog Subsequent 25, combined with the velocity-sensitive and aftertouch-capable keyboard, creates a successful unit for playing captivating basslines and lead melodies. 16 memory slots are distributed across four banks of four presets each. In panel mode, all current settings are queried, making the Subsequent behave like a truly analog synthesizer without memory slots: you get what you see.

Shift Mode in the Moog Subsequent 25

For the Subsequent 25, it is indeed advisable to take a look at the user manual. Here, all global settings and especially all shift functions are described in detail, which significantly enhance the instrument's functionality. Envelope triggering, settings for the LFO such as range, waveform modulation target, and tracking, monophonic or duophonic playing, as well as the number of filter poles (1-4 at 6 dB each) can be switched here, among other options.
