Smooth and Elegant

MELLOW is not only meant for jazz trios. It gives singer-songwriter, RnB and hip-hop styles a soft, soulful, and acoustic realism.

Organic, Hip and Yummy

Virtual Bassist MELLOW—inside is a meticulously-recorded acoustic double bass, played with soul and feeling and implanted into a virtual instrument that adds realism and a player who knows his way around. Smooth and elegant, with an odd sound here and there. At home as a subtle foundation in a jazz trio, as well as a powerful second voice in hip-hop.

Frustration-Free Design

As with every UJAM product, MELLOW benefits from a frustration-free design philosophy, meaning that anyone can make music faster, better, and easier with this product, regardless of their level of experience in music production. Follow the simple  user interface controls to use one of over 60 styles and 1,380 phrases for your tracks.

Features at a Glance

MELLOW’s smooth, soulful and acoustic realism is unique. Even seasoned bass players will appreciate the ability to get great-sounding ideas down fast—with practically no learning curve.

Player Mode

Virtual Bassist MELLOW has two distinct modes—the first, player mode, gives you easy access to UJAMs traditional fail-free GUI and control set. Just set the musical key and decide on the chords for the song, and MELLOW does the hard work—even intelligently choosing the most appropriate articulations to augment your basslines.

Instrument Mode

For those who want more control and are comfortable playing the keyboard, our brand-new instrument mode will let you access the entirety of MELLOW’s meticulously-sampled fretboard with your MIDI controller, complete with dead notes, full stops, and satisfying slides.

Sound-Shaping Options

Add that extra bit of sparkle with a simple yet powerful set of tone-shaping controls, providing separate parameters for many useful sonic and performance-enhancing features. Experiment with amp choices and instant character changers on speed-dial, such as: vibrato level, room reverb level, octave effects as well as dynamics and EQ.
