Checking Out: Mojo Upright Bass by Vir2 Instruments
MOJO Upright Bass by Vir2 Instruments is an impressive virtual instrument designed for musicians and composers seeking authentic upright bass sounds. It’s particularly well-suited for genres like jazz, rock, blues, and rockabilly, thanks to its rich and detailed sampling. The instrument features renowned jazz bassist Stefan “Pista” Bartus, who played a 150-year-old double bass recorded through an analog console, bringing an unparalleled sense of realism and warmth to the sound.

One of the standout features is the user-friendly interface. At first glance, it’s clear that everything is designed to be intuitive. The bottom of the interface offers quick articulation selection, making it easy to switch between different playing styles. Just above that, there are various controls for tweaking the sound, including dials for adjusting the velocity curve, capo, string buzz, hand positions, humanize settings, pitch, attack offset, and different playback modes. It’s a thorough set of options that gives you a lot of control over how the instrument behaves. There’s even a visual representation of the fretboard that animates as you play, which makes it feel more immersive. You’ll also find sliders for player noise and hiss, adding that extra layer of realism, as well as a preset selection at the top center of the interface for loading and saving different sound setups.

The performance panel is another highlight, especially if you’re working with MIDI. This section lets you drag and drop pre-made MIDI performances directly into your DAW, and they sound fantastic. Whether you’re looking for jazz, blues, Latin, or rockabilly grooves, there’s a ton of variety to work with, and it’s all very easy to use.
In terms of sound shaping, the effects panel gives you all the tools you need to customize your tone.

Paired with the mixer panel, which offers control over six mic positions, you have the flexibility to create everything from tight, close-up bass lines to more ambient, roomier sounds or even far-out distorted Rockabilly lines. If you love creating your own presets, you’ll be happy to know you can save and recall custom setups. However, a small quirk in the software prevents the names of saved presets from displaying properly, though they do load just fine.

What really makes MOJO Upright Bass stand out is its range of articulations. It has everything from sustains and legato, with an on/off slider, to hammer-ons and pull-offs that give you even more control. The instrument also automatically recognizes overlapping notes for legato lines, so you don’t have to mess around with key-switching when creating fluid bass lines. Staccato, as you’d expect, limits playback to short notes, while the performance repetition articulation is designed to sound especially natural when playing fast, single-note passages. You’ll also find harmonics, and a cool percussion articulation that lets you trigger any of 20 slap, hit, or breath samples, which can be placed anywhere on the keyboard via drop-down controls. The percussion sounds are available in other articulations too, thanks to magenta keys that correspond to those same drop-down controls. For chord lovers, you get access to staccato chords, sustained chords, and arpeggios, with key-switches allowing you to change chord types mid-performance. It’s all designed to make playing as smooth and intuitive as possible.
There’s also a nice feature where you can force single-string performances, such as slides and glissandos, by using the green keys. This gives you more creative control and opens up the possibility for unique, score-like creations. I really love this aspect of the instrument, especially for programming realistic upright bass performances. The orange keys, on the other hand, let you control various forced release samples, adding even more variety to your sound.
When you combine all these features — the articulations, string slides, percussion, and forced release samples — you can really hear how realistic this instrument sounds. The performance repetitions are particularly effective, and you get a great sense of how lifelike the bass can be, even in faster passages.
The performance tab is another area that shines. It offers a wide range of pre-programmed MIDI patterns, covering genres like jazz, blues, bossa nova, gypsy jazz, Latin, funk, and even rockabilly grooves. You can easily sort these patterns by meter and adjust the key of playback, which makes it super simple to drag and drop them into your DAW for quick use. If you’re anything like me, you’ll appreciate how easy it is to customize performances and see how the instrument’s programming can create something that feels more realistic.
Overall, MOJO Upright Bass leaves a lasting impression as a virtual instrument that offers a highly realistic sound and a versatile set of features. From the ability to adjust mic positions to its extensive articulations and MIDI performance library, it has everything you need to create lifelike bass lines for a variety of genres. While the price might feel a bit steep for some at $249.95, the quality of the sound and the depth of customization options make it a valuable tool for anyone serious about music production.
If you’re after a natural, rich bass sound for jazz, rock, blues, or even more cinematic compositions, MOJO Upright Bassis well worth considering. It’s a deeply customizable and fairly easy-to-use instrument that could quickly become a go-to in your virtual instrument collection.
