What is it?

Monoment Bass (VST/AU/AAX), is a monosynth dedicated to dance music bass sound creation. It mixes three stereo sample layers together to form a raw tone. Sources A and B draw on a 100-strong library of recorded synth samples, while the Analog Dirt layer accesses a smaller roster of 15 noises and five attacks.

The Source sounds were put together in collaboration with sound designer Tobias Menguser, each one captured as three samples per key (every third note, G0 to F3) from his enviable collection of rare analogue and digital synths, including the Nonlinear Labs C15, Modal 002, Kawai K5000 and Jomox Sunsyn.

Sounds are categorised descriptively in the selection menus - Analog Clean, Analog Dark, Digital Noisy, Digital Punchy, Organ, Processed, etc - and the two Sources are blended using the Source Mix knob. Source B can be kicked up or down an octave and detuned by up to 100 cents either way, and an optional frequency crossover enables separation of A and B at anywhere from 20-400Hz – useful, as the Sources can’t be individually filtered.

The Analog Dirt source, meanwhile, is routable to the low-pass filter or straight to the main output, and mixed in with the Aging control, which also dials in subtle random pitch and attack modulation for a more ‘analogue’ sound. Velocity sensitivity can be disabled, and portamento is applied to legato notes only or all notes, with glide time of 0-500ms.

Filter modulation comes in the form of an envelope and an LFO. Monoment Bass’s Effects section, meanwhile, consists of five boiled-down modules, calibrated to best serve the processing of low-end tones.

Performance and verdict

Monoment Bass provides the newcomer to production with a very capable solution for generating powerful, weighty basslines for house, techno, EDM and the like in no time at all. The sample library is laden with thoroughly viable full-fat source material, and the controls couldn’t be easier to get a handle on.

However, while such approachability is generally a good thing, in this case, it does come at the expense of depth, and some of the obvious omissions cut quite deep - proper envelopes, per-Source filtering and shaping, and any form of pitch modulation chief among them.

Essentially a well-made ROMpler, Monoment Bass offers little to meaningfully differentiate it from countless Kontakt libraries.

Also consider

Don’t get us wrong, though: the plugin itself sounds good (in fact, the faux analogue filter and distortion, and effects are quite magnificent) and certainly makes it almost embarrassingly easy to come up with ‘mix-ready’ bass tones in a hurry. It’s just all a bit... underwhelming.

MusicRadar verdict: Sound design novices will have a ball with Monoment Bass, but a fair amount of frustration awaits more experienced users.

"[Monoment Bass] could be a real go-to for basses if you find yourself struggling to get sounds that really sit in your track, especially in the more electronic domain." MusicTech
