Ample Bass Upright is a detailed virtual upright bass instrument featuring a 4.26 GB sample library recorded on every fret without destructive editing or dynamic processing. It includes eight articulations such as Sustain, Mute, Natural Harmonic, Hammer On & Pull Off, and various slide techniques. The legato articulations allow for smooth transitions with customizable duration, speed, pitch, and polyphony. An alternate tuning option supports down to the lowest note B0, enhancing its adaptability for different playing styles.

This bass instrument incorporates a new sample engine designed to deliver expressive performances by blending mic and DI samples for both acoustic and electric tonal qualities. Users can independently mix and process multiple microphone sources capturing the neck, body, and ambient sounds to create rich stereo or focused mono outputs. The fretless slide system is specifically tailored for authentic fretless legato expression. Additionally, the redesigned Tab Player supports all articulations and notation, enabling realistic playback with humanization and multiple capo logics for varied performance scenarios.

Ample Bass Upright also includes a powerful Riffer tool with a String Roll Editor that displays detailed fingering, articulation, and expression attributes for precise lick creation. The Dice feature generates new riffs by analyzing music rules rather than random algorithms. It supports seamless conversion between Riff, MIDI, and Tab formats, preserving all musical nuances. The integrated effects section offers an 8-band EQ, dual-mode compressor, 6-tap echo, and IR reverb with multiple room types, all equipped with real-time visualizations to shape the sound with clarity and depth.
