01Overview

Ample Bass Upright is built around a faithfully sampled upright bass, recorded with neck, body, room microphones and a direct signal. The developer positions it for jazz, blues and soul-style basslines, though its articulations and fretless-focused slide system suit a broad range of acoustic bass parts. The instrument pairs its sample library with Riffer 4, Tab Reader 4 and a set of built-in effects, so producers can sketch, edit and process bass lines within one plugin.

Sound Sources and Articulations

The instrument combines neck, body and room microphone positions with a DI signal, giving you control over how close or open the bass sounds in a mix. Thirteen articulations, including slap, pop and tap, let you shape note attacks and playing style without leaving the instrument.

A polyphonic legato and slide smoother handles transitions between notes, and the instrument supports drop tuning down to D1. Ample Sound says the slide system is tailored for fretless performance realism.

Riffer 4, MIDI Tools and Built-In Processing

Riffer 4 provides dual MIDI views and intelligent fingering, and the library includes a large set of pre-made upright bass riffs to start from. Full MIDI import and export support means you can move lines in and out of your session, and Tab Reader 4 can open Guitar Pro files in the GP3 to GP8 range.

For tone shaping, the plugin includes three classic bass amp models, four cabinet options with four mic types, and an 8-band EQ, compressor, delay and convolution reverb. A chord system designed for non-strumming instruments, swing quantization and one-click vibrato generation add further control over groove and expression.
