Powerful and Energetic

ROWDY confidently adds picked and overdriven electric bass performances to your track, suitable for a variety of styles, from powerful punk to rock and modern metal.

Let’s Get Ready to Rumble

It can be tame, but it’s wild! With a hand-picked, heavily modified vintage bass guitar, hot amps, a fuzz box, and even an octave effect, it’s definitely a rocker and could use a shower—but we’re too scared 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, rebellious sound and angry playing style means that even seasoned bass players will appreciate how easy it is to get great-sounding ideas down fast—with practically no learning curve.

Player Mode

Virtual Bassist ROWDY has two distinct modes—the first, Player Mode, quickly lets you choose from one of 60 styles and 1,380 phrases via your MIDI controller—seamlessly following in an intelligent and musical way—regardless of what key or chord is being played.

Instrument Mode

Instrument Mode is the weapon of choice for keyboard wizards! It opens 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 ROWDY’s powerful yet simple sound-shaping controls. Choose between a DI signal and 3 distinct amplifiers with separate controls for overdrive and fuzz. The character control gives you instant access to many useful sound-characters before you put the cherry on top with an octave effect and a simple EQ and dynamics section.
