Position Control: Think of this as a virtual capo, shifting your virtual playing position up the fretboard, selecting higher frets and creating a rounder sound - just like in real life.

Force String: Gain complete control over your tone, allowing you to choose exactly which string is used for every note.

Pitch Bend: Bend the notes (and vibrato) up to 12 semitones!

Why Virtual Bass?

  • For Musicians

    If you're writing and producing your own music, a MIDI bass can be a real game changer. It's simple: it saves you time. Instead of getting caught up in the details of recording a bass track, you can add a MIDI bass line to your project. It sounds great and it's super flexible – you can tweak it until it fits your song right. Now you can stay focused on the song, not the bass part. We want to make it easier for you to create music and record your ideas.

  • For Studio Engineers

    It's a reality in the studio world – sometimes the real bass track just doesn't cut it. Maybe there's a quality issue or time is running short. That's where our virtual bass comes in. It's not just for sketching out ideas; our instruments have replaced real bass tracks on final studio records more often than you'd think. Think of it as an insurance policy: having a solid MIDI bass option means you're covered, no matter what happens during recording. It's about having that reliable, high-quality sound ready at a moment's notice.

  • For Pre-Production

    A lot of big-name producers have given us props for one simple reason: speed and realism. With our virtual bass, you can quickly lay down a MIDI bass line that's not just realistic, but also perfectly in tune. It's a solid foundation that a lot of pros use to anchor their guitar recordings. They appreciate not having to fuss over getting the bass part just right before moving on to guitars – it's all about keeping the session flowing smoothly.

It's like having Simon Grove as your Bassist!

It’s as if Simon Grove himself is jamming right in your music. Whether you’re a seasoned music-making genius or just starting out, this plugin is your new best friend. Honestly, it captures the essence of a real bass player, offering incredible versatility and sound quality. I created a sample of modern fusion and progressive rock song with the GroveBass and my Neural DSP Plugin Archetype - Plini X, and it delivered the crystal-clear, punchy bass lines that effortlessly goes along well with my guitar as it cut throughout the track and production period.

Honestly, I recommend the product because GroveBass is your go-to for awesome bass sounds, no matter your skill level or style.

Versatile Bass Sound!

GroveBass is very versatile and it serves the low ends of songs in genres other than metal very well.

Very good with small advice

This one is my fourth bass library from SubmissionAudio - I really appreciate the clean interface (would like to have that in all the other SA basses :) I like its sound but for some reason I feel/hear too much scratch-attack on the start of every note, so I would appreciate some envelope settings here just to adjust an attack (or some "scratch-remover"). Also I really dont know what is the purpose of the "LEAD" settings here - what is the usecase for this one? Overall 4,5*

Michal Suchy
Just a versatile pro sound

Sounds just fantastic. Does the job in both metal and various delicate styles of music. Sits in the mix great. Fills low end, but can decorate middle and high spectrum as well. Using it with a lot of fun.

Robert Case
Grove Bass is a must!

Grove bass is absolutely amazing! It sounds so good! If you are thinking about it…just get it. You won’t regret it.
