Purpose Built Separation
For Banjo & Fiddle

Create isolated stems, instrument-removed mixes
and slowed-down tracks for easier learning.

VRII Bluegrass Stems on a phone and tablet, with individual instrument controls.

Most stem splitters are built around the usual instruments: vocals, drums, bass, guitar, and piano. VRII Bluegrass Stems does that too. But VRII goes further with purpose-built separation algorithms for Banjo and Fiddle — two instruments that most stem splitters either ignore, struggle with, or bury inside a generic “Other” category. If you are trying to learn a banjo roll, isolate a fiddle phrase, remove the original instrument, or create a practice track, “Other” is not good enough. With VRII, Banjo and Fiddle are not “Other.” They are dedicated separation targets.

Hear the Part. Learn the Part.
Remove It. Play It Yourself.

VRII is more than a stem splitter. It is a practice and learning tool built for musicians. Upload an audio or video file, choose the instrument you want to isolate or remove, and VRII will process the track using AI-powered stem separation.

Depending on the instrument selected, VRII can give you:

The isolated instrument stem
The full mix with that instrument removed
A slowed-down version of the isolated stem
A slowed-down version of the instrument-removed mix

That means you can do more than simply hear an instrument by itself. You can remove the original musician from the recording, step into that space, and play the part yourself with the rest of the band.

Purpose-Built Algorithms for Banjo and Fiddle
Not Buried Inside the “Other” Category

Dedicated VRII Banjo separation software box.

Banjo parts can be fast, complex, and difficult to hear inside a full mix. Rolls, fills, backup patterns, and solos often get buried behind vocals, guitar, bass, mandolin, fiddle, and other instruments.

VRII’s Banjo separation is purpose-built to help you:

Isolate the Banjo from a full recording
Hear rolls, licks, fills, and solos more clearly
Remove the Banjo and play the part yourself
Create Banjo practice tracks from songs you already know
Slow down the Banjo stem to study difficult passages

Hear the Banjo clearly — or remove it and become the Banjo player.

Fiddle parts can be just as challenging. Bowing patterns, ornaments, fills, double stops, and fast melodic phrases can be difficult to pick out when the full band is playing.

VRII’s Fiddle separation is purpose-built to help you:

Isolate the Fiddle from a full mix
Hear phrasing, timing, bowing, fills, and solos
Remove the Fiddle from the original recording
Practice or perform with the rest of the band
Slow down the Fiddle stem to learn difficult parts more easily

Hear the Fiddle part. Learn it. Remove it. Then step in and play it yourself.

VRII is focused on bluegrass, acoustic, roots, and learning-based workflows — but it is not limited to Banjo and Fiddle.

VRII also separates the standard instruments musicians expect:

Vocals
Drums
Bass
Guitar
Piano
Banjo
Fiddle
Mandolin(Coming Soon)

Whether you are a singer, guitarist, bassist, drummer, pianist, banjo player, fiddle player, teacher, student, or transcriber, VRII gives you a practical way to hear and work with individual parts inside a complete recording.

AI Stem Separation for Audio + Video

VRII accepts WAV, M4A and MP3 audio, and MP4, MOV and MKV video; it produces isolated, instrument-removed and slowed-down results.

VRII works with both audio and video files. If you upload a video file, you can have VRII return only the audio, or ask it to insert the audio stem back into the video and return a video file.

That means you can use it with:

Songs
Rehearsal recordings
Practice tracks
Music videos
Performance videos
Live performance clips
Lesson material

Upload your file, select your instrument, and let VRII separate the part you want to hear, study, remove, or slow down.

Slow It Down. Learn It Faster.

Some parts are simply too fast to learn at full speed. That is why VRII does more than isolate stems. VRII can also create slowed-down versions of your processed files, making it easier to hear details that fly by too quickly in the original recording.

Use slowed-down stems to study:

Banjo rolls
Drum patterns
Fiddle phrases
Vocal phrasing
Guitar runs
Fast solos
Bass lines
Difficult transitions
Piano passages

Compare an original waveform at 100% with slowed versions at 50% and 25%.

And because VRII can also slow down the instrument-removed mix, you can practice your part at a more comfortable speed before working back up to the original tempo.

Stop Playing Over the Original Musician

Most musicians practice by playing along with a recording. But there is one problem:

The original musician is still there. You are playing over the original Banjo, Fiddle, Guitar, Piano, Bass, Drum, or Vocal part. VRII changes that.

Practice with the band: banjo, fiddle, guitar, piano, bass and drums.

Remove the original instrument from the mix, then play that part yourself.

Remove the Banjo and take over the Banjo part.
Remove the Fiddle and become the Fiddle player.
Remove the Guitar and practice with the rest of the band.
Remove the Vocal and sing the lead yourself.
Remove the Bass, Drums, or Piano and step into that role.

Instead of playing over the original musician, you can practice with the band.

Why VRII Is Different

Most stem splitters stop at the usual instruments. Vocals. Drums. Bass. Guitar. Piano. Maybe “Other.” That works fine until the instrument you care about gets trapped in the wrong category. VRII was built to go further. VRII includes dedicated AI-powered separation for Banjo and Fiddle, making it especially useful for bluegrass, old-time, folk, country, acoustic, and roots musicians. VRII is built for learning, not just splitting. The goal is not merely to create stems.

The goal is to help you:

Hear the part
Learn the part
Remove the original instrument
Slow the track down
Practice with the band
Play the part yourself

That is what makes VRII different.

Comparison: standard stem splitters separate vocals, drums, bass, guitar and piano. VRII also provides dedicated Banjo and Fiddle separation.

Built for learning: hear, learn, remove, slow down, practice and play.
