Powerful & Energetic

ROWDY confidently delivers picked overdriven electric bass sounds suitable for a variety of styles, ranging from powerful punk to red-hot rock and modern metal.

Let’s get Ready to Rumble

It can purr, but it’s built to roar. With a hand-selected, specially modified vintage bass guitar, hot amps, a fuzz box and even an octaver. It’s definitely a rocker and could also do with taking a shower but we’re too afraid to ask...

Frustration-Free Design

Designed with the UJAM frustration-free philosophy, ROWDY’s easy to use GUI and controls make it possible to achieve fantastic sounding and aggressive basslines in no time – no matter what your level of music production experience is.

Features at a Glance

ROWDY’s loud-mouthed, rebellic sound and angry playing style means that even seasoned bass players themselves will appreciate the ability to get great sounding ideas down fast – with practically zero learning curve.

MIDI Drag and Drop

Drag and Drop your favourite phrases into the bass track of your DAW and tweak every little detail.

Show Some Character

Select one of the four sound characters effecting the dynamic range as well as the overall sound of the instrument.

Crank up the AMP

Select between one of three AMP settings that are ready to rock or go for the DI signal.

Finish it!

15 complex yet simple-to-control multi-effect modes allow you to take the sound to the next level.

Player Mode

Virtual Bassist ROWDY has two distinct modes – Player Mode lets you quickly choose from one of the 60 styles and 1380 phrases with your MIDI controller, seamlessly following in an intelligently musical way whatever key or chord is being played.

Instrument Mode

The Instrument Mode is one for the keyboard wizards and opens up the entire ROWDY fretboard to be played like a traditional sampler, complete with dead notes, full stops and even slides.

Tone-Sculpting Controls

Perfect your performances and sound with Virtual Bassist ROWDY’s powerful yet simple tone-sculpting controls. Choose between a DI signal and 3 separate hand-picked amps with separate dial-in controls for overdrive and fuzzy rudeness. The character knob can then give you instant access to many useful scuzzy sonic flavors before adding the cherry on top with an octaver and a simple EQ and dynamics section.

PreSonus Chord and Key Track

With the new Virtual Bassist 2.1 update we will provide Studio One users running on version 4.6.2 or later with an exclusive PreSonus chord and key track feature! Descriptions of styles and phrases are displayed on the piano roll to help you find the right styles and phrases faster and easier for your track. The new chord track feature in Studio One automatically follows the chords and automatically changes the MIDI notes for you.
