# Studio One / Fender Studio Pro Stem Separation in 2026: AI Stem Splitter, Native Stem Separation & iZotope RX 12 Compared

Studio One has had native AI-Powered Stem Separation since **Studio One Pro 7** (October 2024) — a real advantage over Pro Tools, which still has nothing built-in. The DAW also rebranded to **Fender Studio Pro** in January 2026 after the Fender/PreSonus alignment, and the current shipping version is **Fender Studio Pro 8**. The stem-separation feature carries forward; everything below works identically whether your install says "Studio One Pro 7" or "Fender Studio Pro 8".

**The short answer:**

- For the cleanest possible stems on modern music → **external AI (StemSplit)** at $0.10/min — drag the WAVs straight onto a new track in your session.
- For the fastest in-DAW workflow → **native AI-Powered Stem Separation** built into Studio One Pro 7 / Fender Studio Pro 8 (vocals, drums, bass, other). Free with the DAW.
- For the pro repair workflow → **iZotope RX 12 Spectral Editor via ARA 2** ($399 RX Standard / $1,399 Advanced) — Studio One is one of only two DAWs that supports this (Logic Pro 10.7+ is the other). For rebalancing, use **Music Rebalance** as a standard VST3 insert or RX standalone via RX Connect.
- For free workarounds → Phase cancellation, EQ. Limited. Honest answer: not competitive with AI on modern music.

This guide walks through every method honestly and tells you which to use when.

[Try StemSplit on your Studio One session →](/stem-splitter)

## Method 1: StemSplit (External AI, Best Quality, Drag-and-Drop into Track)

This is the cleanest, fastest, cheapest option. Works on every Studio One / Fender Studio Pro edition. Browser-based; you bring the separated WAVs back to the session as audio events on new tracks.

### Workflow

1. **Bounce the source from Studio One** — Track → Export Mixdown (or Event → Bounce to New File) → WAV at session sample rate. Or upload the source file directly without bouncing.
2. **Upload to [StemSplit](/stem-splitter)** → choose 4-stem (vocals, drums, bass, other) or 2-stem (vocals + instrumental).
3. **Download the stems** as WAV files.
4. **Drag the WAVs onto new tracks** in Studio One — drop directly into the arrangement at the original timestamp. Group them into a Folder Track for clean session organization.

The model is htdemucs FT — ~8.4 dB SDR in published benchmarks. Cleaner than Studio One's native AI Stem Separation on dense modern productions, and well above any AudioSuite-style workaround.

### When to use this method

- You need release-quality stems for music mixes, sample packs, references, or remix work
- You're on a Studio One/Fender Studio Pro edition without the native Stem Separation feature, or older than Studio One Pro 7
- You want the absolute peak quality the model space offers
- One-off jobs where you don't want to bounce the source through the DAW first
- You're working on iPad/laptop without your full plugin chain

### Pricing reality check

$0.10/minute. A 3-minute song = $0.30 in credits. Free with a 30-second preview before you pay. No subscription, no DAW upgrade required.

### Studio One / Fender Studio Pro-specific tips

- **Match sample rate** to your session before separating to avoid resampling artifacts.
- **Use Folder Tracks** — drop the four returned stems into a Folder Track for grouped mute/solo and a single composite fader.
- **Bus the stems through a Stem Bus** — route all four to a single Group/Bus track for parallel processing or master-bus FX printed to the stems.
- **Use Listen Bus / Cue Mixer** to reference the original bounce against the recombined stems while you mix.

## Method 2: Native AI-Powered Stem Separation (Studio One Pro 7 / Fender Studio Pro 8)

PreSonus added native AI stem separation in Studio One Pro 7 (October 2024); it carries forward into Fender Studio Pro 8 unchanged. Free with the DAW. Four stems: **Vocals, Drums, Bass, Other**.

### Workflow

1. **Drop the source audio onto a track** in your session
2. **Right-click the audio event** → **Stem Separation** (or Audio menu → Stem Separation)
3. Studio One processes the file locally and creates four new tracks — Vocals, Drums, Bass, Other — with a Folder Track grouping them
4. The original event is muted automatically; you can solo, mix, or process the stems individually

### Edition gating (2026)

Note: with the **Studio One Pro 7** licensing change (continued in **Fender Studio Pro 8**), Artist and Prime tiers were retired in favor of a single flagship SKU. If you're on the modern flagship — **~$199.99 perpetual** for Fender Studio Pro, or the **Pro+ subscription** (~$179.99/year, ~$19.99/month) — native Stem Separation is included. Legacy Studio One Artist licenses do not include the feature.

### When the native feature is the right answer

- You want to stay entirely inside the DAW with no upload step
- You don't need release-grade quality (drafts, references, quick edits, samples for sketching)
- You're working offline / no internet at the studio
- Privacy-sensitive material that can't leave your machine
- You want stems automatically grouped on the timeline at the original position

### Honest limitations vs StemSplit

- Quality is good but **not class-leading** — htdemucs FT (StemSplit) outperforms the native engine on dense modern productions in side-by-side listening
- Locked to four stems (vocals, drums, bass, other) — no piano/guitar/2-stem modes
- Processing time scales with track length and CPU
- Requires you to bounce the source to audio first (no real-time on a virtual instrument bus)

For drafts and sketches, native is genuinely fast and convenient. For final-grade stems on modern music, StemSplit still wins.

## Method 3: iZotope RX 12 Spectral Editor via ARA 2 (Studio One's Pro Tools Advantage)

This is where Studio One pulls ahead of Pro Tools. **iZotope RX 12 Spectral Editor** runs as a **VST3 ARA** plug-in in Studio One Pro 7 and Fender Studio Pro 8 — officially listed in iZotope's RX 12 spec sheet (the only other supported host is Logic Pro 10.7+ via AU ARA). Pro Tools doesn't get this at all.

### What ARA 2 buys you

ARA 2 means RX Spectral Editor sees the entire audio event on the timeline non-destructively. You paint out clicks, mouth noise, hum, broadband noise, or surgical artifacts directly on the spectrogram inside Studio One — no bouncing back and forth, no Direct Offline Processing dialogs, no re-renders. Edits commit on close and stay editable on re-open.

### Workflow

1. **Insert RX 12 Monitor** as a VST3 plug-in on the track you want to repair
2. **Right-click the audio event** → **Edit with RX 12 Spectral Editor (ARA)**
3. RX opens with the event waveform/spectrogram loaded. Paint, repair, de-noise, de-click as needed.
4. **Close RX** — edits commit non-destructively to the event in Studio One. Re-open at any time to revisit.

This is dramatically faster than the offline RX Connect workflow used in Cubase, Pro Tools, or any AAX-only DAW.

### Cost

| Edition | Price | Includes Spectral Editor (ARA)? |
|---|---|---|
| RX 12 Elements | $99 | No |
| **RX 12 Standard** | **$399** | **Yes** (plus Music Rebalance, Stems View) |
| **RX 12 Advanced** | **$1,399** | **Yes** (plus Scene Rebalance for post) |
| **Music Production Suite 9** | **$799** | **Yes** (RX Standard bundled) |

### Music Rebalance and Scene Rebalance (the rebalance modules)

Important: iZotope's published RX 12 ARA host list only includes **Spectral Editor** for Studio One — not Music Rebalance or Scene Rebalance. In practice that means:

- **Music Rebalance** in Studio One: run as a regular VST3 plug-in insert on the track. Adjust the four stem sliders (vocals, drums, bass, other) at -∞ for what you want to remove, 0 dB for what you keep. Render via Event → Bounce.
- **Scene Rebalance** (RX 12 Advanced, dialogue/music/effects for post): same — VST3 insert or standalone via RX Connect.
- **RX Connect** round-trip is also available (Track → Bounce, send to RX standalone, return processed audio).

### When this is the right combo

- You already own iZotope RX (most pro Studio One mix engineers do)
- You need surgical spectral repair (mouth de-click, breath de-ess, hum removal, isolated noise events) — this is where ARA Spectral Editor in Studio One genuinely beats Pro Tools workflow
- You're doing dialogue/voiceover/podcast mixing in Studio One
- You want non-destructive repair that survives session reopens

### Honest limitations vs StemSplit

- RX 12 Music Rebalance is solid but **htdemucs FT** (StemSplit) still produces marginally cleaner stems on modern music
- The $399 entry for RX Standard is hard to justify if separation is your only need
- Music Rebalance is fixed at 4 stems — same as the native Studio One feature

For most users, StemSplit (peak quality) + native Studio One Stem Separation (in-DAW convenience) covers 95% of needs. RX makes sense when you also need its broader repair toolkit.

## Method 4: Manual Workarounds (Free, Limited)

If you don't have native Stem Separation (older edition, legacy Artist license) and don't want external tools, Studio One's stock plug-ins can do limited "vocal reduction." Honest assessment: not competitive with AI on modern music.

### Phase cancellation

1. Duplicate the stereo audio onto a new track
2. On the duplicate, split to dual mono (Audio → Convert to Mono Tracks) and invert one side
3. Sum to mono — centred content cancels (vocal, kick, bass)
4. The result is everything *not* in the centre of the stereo field

Why it fails on modern music: vocals are wide (reverb, doubling, stereo widening), so they don't fully cancel. Bass and kick *are* centred — they cancel along with the vocal. You get a leaky, bass-depleted mix.

### Spectral notch with Pro EQ3

1. Insert **Pro EQ3** on the source track
2. Cut a wide notch at 1–4 kHz (vocal presence) by -6 to -12 dB
3. The vocal becomes quieter; the rest of the mix gets hollow

For surgical spectral work, use Method 3 (RX Spectral Editor ARA) — it's the right tool. Stock EQ alone won't get clean results.

## Method Comparison

| Method | Quality | Setup | Cost | Best For |
|---|---|---|---|---|
| **StemSplit (external AI)** | Excellent | None | $0.10/min | Modern music, release-grade stems, no setup |
| **Native Stem Separation (Studio One Pro 7+ / Fender Studio Pro 8)** | Good | None (in-DAW) | Included with DAW | Drafts, fast in-session work, offline |
| **RX 12 Spectral Editor (VST3 ARA)** | Excellent (for repair, not separation) | Plug-in install | $399–$1,399 | Surgical repair, dialogue, podcast mixing |
| **RX 12 Music Rebalance (VST3 insert)** | Very Good | Plug-in install | $399+ | Existing RX owners, in-session rebalance |
| **Manual phase/EQ tricks** | Poor on modern music | None | Included | Last resort only |

For most Studio One / Fender Studio Pro mixers, the right pairing is:

- **StemSplit** for peak quality on release-bound stems
- **Native Stem Separation** for everything in-session that doesn't need to be class-leading
- **RX 12 Spectral Editor (ARA)** for surgical repair — Studio One's killer Pro Tools advantage

## Studio One / Fender Studio Pro-Specific Tips

**Group separated stems in a Folder Track.** Whether the stems came from the native feature, StemSplit, or RX, drop them into a Folder Track so mute/solo/level moves stay logically grouped.

**Match sample rate before separating.** Most music sessions are 44.1 kHz or 48 kHz. Mismatched rates introduce resampling artifacts. Bounce at session rate, separate, import.

**Use the Listen Bus / Cue Mix** to reference the original mix against the recombined stems while you tweak — Studio One's Cue Mixer is one of the best implementations of this in any DAW.

**Bounce flat before separating.** Disable Event FX, clip gain, and channel inserts on the source bounce — pre-bounce processing leaks into the AI's view of the mix and produces messier stems.

**Use Track Layers** for stem versions. Studio One's Layers feature lets you keep multiple takes/versions of a stem on the same track for A/B comparison — handy when you've got native, StemSplit, and RX versions of the same separation to choose between.

**Stack Folder Tracks for hierarchical mixing.** Stems folder → Drums sub-folder (with kick/snare elements) → individual elements. Studio One's nested folder behaviour makes complex stem-based mixing tractable.

## Frequently Asked Questions

### Does Studio One have built-in AI stem separation?

Yes — since **Studio One Pro 7** (October 2024). The feature is called **AI-Powered Stem Separation** and produces four stems: vocals, drums, bass, and other. It carries forward unchanged into **Fender Studio Pro 8** (the January 2026 rebrand). Right-click an audio event and choose Stem Separation. The native engine is a strong default, though external tools like StemSplit (htdemucs FT) still produce cleaner results on dense modern productions.

### What's the best stem splitter for Studio One / Fender Studio Pro in 2026?

For peak quality, **StemSplit** produces the cleanest stems — htdemucs FT outperforms both the native Studio One engine and iZotope RX 12 Music Rebalance on modern productions, at $0.10/min. For free in-DAW convenience, the **native Stem Separation** (Studio One Pro 7+ / Fender Studio Pro 8) is a great default. For surgical repair workflows, **iZotope RX 12 Spectral Editor via ARA 2** is the killer pro tool — Studio One is one of only two DAWs that supports it.

### What changed when Studio One became Fender Studio Pro?

In January 2026, PreSonus rebranded Studio One to **Fender Studio Pro** following the Fender/PreSonus alignment. The codebase and feature set continued — version numbering moved to **Fender Studio Pro 8**. Native Stem Separation, ARA 2, Melodyne integration, the Cue Mixer, Folder Tracks, and the entire pro feature set carry forward unchanged. Existing Studio One Pro 7 licenses continue to work; new buyers get Fender Studio Pro 8.

### Does Studio One support ARA 2?

Yes — fully. Studio One has been an ARA / ARA 2 leader since the early Melodyne days. In 2026 the supported ARA 2 plug-ins commonly used in Studio One include **Celemony Melodyne**, **Steinberg SpectraLayers**, **iZotope RX 12 Spectral Editor**, **Synchro Arts Vocalign / RePitch / Revoice Pro**, **Antares Auto-Tune Pro X**, and **Dreamtonics Synthesizer V**. This is a meaningful advantage over Pro Tools (no ARA 2 in 2026).

### Can I use iZotope RX Spectral Editor as ARA in Studio One?

Yes. iZotope's RX 12 spec sheet officially lists **VST3 ARA** support for **Studio One 7 / Fender Studio Pro 8**. Insert RX 12 Monitor as a VST3 plug-in on the track, then right-click the event → Edit with RX 12 Spectral Editor (ARA). Edits commit non-destructively. Note: Music Rebalance and Scene Rebalance are not ARA in Studio One — use them as VST3 inserts or via RX standalone.

### How much does Fender Studio Pro 8 cost?

About **$199.99** for the perpetual license, or the **Pro+ subscription** at roughly **$179.99/year** or **$19.99/month** (subscription includes ongoing updates and the cloud features). Pricing varies by region and promotion — check fender.com or major retailers at purchase time. Native AI Stem Separation is included with the flagship license at all tiers above the legacy Artist edition, which has been retired.

### Is Studio One's native Stem Separation as good as StemSplit?

Honest answer: it's good, but not class-leading. The native engine is fast, in-DAW, and free with your license — perfect for drafts, sketches, and reference work. For release-grade stems on modern music, **StemSplit** (htdemucs FT) consistently produces cleaner separation with less bleed and fewer artifacts. Use the native feature for speed, StemSplit for quality.

### What sample rate should I bounce from Studio One for stem separation?

Match your session rate. 44.1 kHz is the music standard; 48 kHz for video/post; 96 kHz for high-end music sessions. Don't upsample before separation — it doesn't add information. Both StemSplit and the native Studio One feature handle 44.1 / 48 / 88.2 / 96 kHz correctly.

### Will Studio One add real-time stem separation?

The native AI-Powered Stem Separation is offline by design — it processes a source clip and creates new tracks. As of Fender Studio Pro 8 (2026) there's no real-time stem separation insert. iZotope RX 12 added real-time AAX Music Rebalance for Pro Tools in April 2026, but no real-time VST3 equivalent has appeared for Studio One yet.

### Does Studio One run native stem separation locally or in the cloud?

Locally. The native engine processes on your CPU with no cloud dependency — that's why it works offline and respects privacy-sensitive material. Processing time scales with track length and CPU. StemSplit, by contrast, is cloud-based; faster on long files but requires an internet connection.

### Can I batch process multiple tracks at once with native Stem Separation?

Yes. Select multiple audio events in the arrangement, right-click → Stem Separation. Studio One processes them sequentially and creates Folder Tracks for each set of stems. For very large batches, StemSplit's parallel cloud processing is typically faster wall-clock.
