Sound Sources and Mixing Control

The electric basses are sampled both from the direct input (DI) and from an amplified source. A blend knob lets you phase-align the two signals or choose one or the other. For the upright bass, the same knob mixes the direct input with a tube microphone capture from the same sessions.

Onscreen controls adjust pitch bend range, pick noise and fret noise, release layers and the velocity curve. A set of built-in effects includes an octaver, compression, saturation, lo-fi, distortion, limiter, phaser, flanger, chorus, reverb and delay.

Performance Tools and Articulations

BASiS includes a legato tool intended for smooth, finger-style transitions between notes. Its vibrato engine offers control over vibrato type, speed and depth. Rather than using a traditional LFO-based vibrato, the developer models vibrato on the playing of real bass players, and it can be controlled from the keyboard or the interface.

The library covers hammer-ons, pull-offs, slides, slaps, rakes and falls. Randomized pick noises, release samples and fret noises are included to add realism to each instrument.
