 Huge collection of Bass for all styles of music!

 BASiS is the ultimate library for all types of bass from Vir2 Instruments

Electric, upright, fretless and synth basses in a 7 GB package and 24 bit quality. Classics such as Jazz Bass, P-Bass, Rickenbacker, Musikman, Motown Bass, Gospel Bass, Jacos´s Fretless and Macca´s Hofner were sampled with great care and taking their personal characteristic sound into account. An upright bass and three slap basses are also included. In the synth bass section there are more than 100 patches that shake your stomach from the dull vintage bass to the current techno bass.


All e-basses were recorded by Direct In (DI) as well as "amped" and can be blended in phase on the user interface of the contact player! With the Upright Bass, the same control is used to set the Direct In and Tube Mic output ratio. Furthermore, the user interface Pitch Bend values, Pick Noise & Fret Noise, Release Layer, envelope curve of velocity (velocity), equalizer functions can be adjusted to your own preferences. Effect devices such as octaver, compressor, saturation, lo-fi, distortion, limiter, phaser, flanger, chorus, reverb and delay are of course also part of the game!

An innovative legato tool, an adjustable vibrato engine and random pick & fret noises & release samples again contribute to the authentic bass playing.  

BASiS includes an impressive number of features and custom engines designed specifically for this library tailored to the unique characteristics of the basses.

Amp / DI control

Amp / DI

Each electric bass includes an Amp / DI balance knob, allowing full blending control between phase-accurate samples of the direct bass signal and an amped recording of the same take. The user can turn the knob to output 100% of one or the other, or blend the two seamlessly, resulting in a vast amount of tonal variety to help the bass fit into any mix. For convenience, the knob can also be controlled via external MIDI continuous controllers. A similar control is available in the upright bass, but it blends the direct signal with a mic´ed signal.

Realism engines

RealismA number of custom engines are designed to contribute to the realism of the sound. A breakthrough intelligent legato mode allows for real finger legato playing, and the engine automatically responds to the playing style to interpret a realistic legato. Adjustable pick noise, fret noise, and finger releases (the sound of the finger lifting off the string at the end of each note played) help recreate the basses completely authentically. A Humanize engine further extends the realism by introducing slight variations in each note played, avoiding the dreaded machine-gun effect. Fret noise is added, not by a random routine, but by an artificial intelligence engine that watches for where the player is moving on the virtual fretboard.

Modes and Articulations

An onscreen display gives real-time information on the currently selected articulations, playing mode (polyphonic, monophonic, and legato), and release layers. Varying articulations were recorded for each bass, including long notes, harmonics, mutes, slides, slaps, pulloffs, falls, releases, noises, and more. Both traditional keyswitching and forced keyswitching (hold down the keyswitch trigger to affect the note (s) currently being played but return to the previous mode as soon as the keyswitch trigger is released) have been designed for maximum ease of use, and all are displayed on the onscreen display in real-time. The end result is that BASiS is able to interpret any style of incoming MIDI playing and render a completely realistic bass part with a minimum of manual-reading.


Character vibrato

Full vibrato control, painstakingly modeled after vibrato made by real bass players, is available, including seven different characters of vibrato.

 Dynamic responseEdit effect

An adjustable velocity curve allows for fine-tuning of the dynamic response of the basses.


A full suite of effects is included in BASiS, including a custom-written Octaver, and full EQ controls. Each of these effects offers a full page of tweakable settings that can be adjusted.

Remote control

Every parameter in the onscreen BASiS engine (including its subpages) can be controlled remotely via MIDI continuous controllers (CC´s), and can be adjusted in real time.
