01Overview

MELLOW 2 is built around a sampled acoustic double bass played by a virtual bassist. UJAM describes the sound as smooth and elegant, with body, texture and a big bottom end. The plugin is aimed at producers who need acoustic bass parts without recording a player, and its frustration-free design lets you generate bass lines by setting a key and chords. Its styles cover jazz trios as well as singer-songwriter, R&B and hip hop productions.

03In depth

Sound and Character of the Upright Bass

MELLOW 2 focuses on a fingered acoustic upright bass. UJAM says the instrument moves from smooth to powerful, and that the samples were meticulously recorded and include dead notes, full stops and slides.

The sound shaping section offers a simple set of controls, including amp selection, dial-up character changes, note vibrato level, room reverb level, octave effects, dynamics and EQ. These options let you move the bass from a soft jazz foundation to a more forceful second voice in hip hop.

Player Mode and Instrument Mode Workflow

Player Mode is the easiest entry point. You set the musical key and chords, and MELLOW chooses articulations to build its bass lines from the 60 styles and 1380 phrases.

Instrument Mode is for producers who are comfortable playing a keyboard. It lets you play the full sampled fretboard from a MIDI controller. The plugin also supports MIDI drag and drop, so you can move generated parts into your DAW.
