Quick Answer
Xfer OTT is Xfer Records’ free three-band upward/downward compressor—a standalone clone of Ableton Live’s Multiband Dynamics “OTT” preset, not the existing how-to-use-OTT-on-synths tutorial, not FabFilter Pro-C 3, and not a compressor list. Official freeware table as of this September 2026 fetch: v1.37 installers—Mac Install_Xfer_OTT_137.dmg (VST, AU, AAX) and Windows Install_Xfer_OTT_137.exe (VST, AAX; 1.33 added VST3). Support article: those installers live on the freeware page.[1][2] KVR product card: Free, version 1.3.7, VST / VST3 / AU / AAX, copy protection none. Production Expert: no account, no iLok; Intel and Apple silicon.[3][4] KVR/Xfer blurb: a re-creation of an aggressive multiband upwards/downwards compressor setting used by dubstep and electro producers. Depth, Time, input/output gain, and a three-band display.[3]
This Page Is Xfer OTT the Plugin. It Is Not the Synth How-To.
Stay here for the Xfer Records OTT SKU: where to download it, v1.37, formats, what the official freeware notes actually say, and how it differs from Ableton’s built-in preset. Do not use this file as the related “how to use OTT-style multiband on synths” tutorial, a FabFilter Pro-C 3 review, a free-compressor list, an Ozone Master Assistant walkthrough, or a Spire preset article.
Ableton Live already has an OTT preset inside Multiband Dynamics. Xfer’s plug-in exists so other DAWs (and Live users who want that preset as a separate device) can load the same idea. EDMProd’s 5 July 2023 guide is the independent explainer of that origin and of Xfer’s knobs—not Xfer’s manual.[5]
Related how-to slug covers usage patterns. This file is the dedicated product page those related links exist to avoid duplicating.
Facts: Free v1.37. Freeware Page. No iLok on the Cited Review.
Cite xferrecords.com/freeware for the installer names and changelog lines. Cite KVR for the 1.3.7 listing. Do not invent a 2026 GUI rewrite beyond what those pages print.[1][3]
| Fact | What the cited pages say | What you should not assume |
|---|---|---|
| Price / DRM | Freeware table; KVR copy protection none; Production Expert: no details, no iLok[1][4] | Not a Serum license. Not an iLok product. |
| Version | Official installers v1.37; KVR lists 1.3.7[1][3] | Not a silent 2026 2.0. Recheck the freeware table. |
| Mac formats | Freeware row: VST, AU, AAX; 1.31 ARM native; 1.34b AAX; Silicon AAX noted at 1.35[1] | Not “AU on Windows.” |
| Windows formats | Freeware row: VST, AAX; 1.33 added VST3 and new UI[1] | Not a Linux build on that table. |
| Origin | KVR: re-creation of an aggressive multiband up/down setting; EDMProd: named after Ableton’s OTT preset[3][5] | Not a claim Xfer owns Ableton Live. |
Three Bands, Upward and Downward. Depth Is the Blend.
KVR feature list: Depth scales the amount of compression; Time scales attack/release of all bands; input and output gain; visual display of input and gain reduction on low/mid/high.[3]
Production Expert: from v1.33 the GUI is resizable. Three bands (High, Mid, Low) with per-band isolate; white line = original, yellow = compressed; green zone = downward, yellow zone = upward. Four knobs above: Depth, Time, In Gain, Out Gain. Depth is a dry/wet blend. Time is attack/release across all bands. Two knobs below: Upward and Downward amounts.[4]
EDMProd: Xfer’s plug-in uses much of the same idea as Live’s OTT preset but not all of Live’s controls. EDMProd reports fixed crossovers at 88.3 Hz and 2.5 kHz and no crossover knobs on Xfer OTT. That is a 2023 tutorial measurement, not an Xfer spec sheet—do not treat it as a vendor PDF.[5]
- Ableton vs Xfer Live’s Multiband Dynamics preset is the namesake and, in Live, still the more editable device (crossovers, per-band timing). Xfer OTT is the cross-DAW plug-in. Keep both names straight.[5]
- v1.33–1.37 notes on the freeware table 1.33: new UI, VST3. 1.34/1.34b: VST3 recall fixes, AAX. 1.35: VST3 ID mismatch fix versus 1.33/1.34 (projects that saved the broken VST3 ID may not find the plug-in). 1.37: VST2 settings import into VST3 so you should not need to delete VST3 in FL Studio or Cubase to load old settings.[1]
- Rekkerd on 1.35 13 May 2022: Xfer updated OTT to v1.35 for UI scaling and the VST3 ID fix. Independent changelog echo of the freeware table, not a 2026 release.[6]
Download: xferrecords.com/freeware. No Account on the Cited Review.
Xfer support: “OTT installers for Mac and Windows can be found on the freeware page.” Production Expert: go there, download, no details required; AAX, VST, and AU; Intel and Apple silicon; no iLok.[2][4]
If an old session loaded 1.33/1.34 VST3, read the freeware warning before you overwrite the installer. Xfer says they can still send 1.33/1.34 via support if you need the old VST3 ID.[1]
On Synths and Drums: Product Notes, Not the How-To Article
Default Depth on a new instance is commonly 100%—Production Expert and EDMProd both treat Depth as the first pull-back. This product page does not republish the related synth how-to. Use that slug for gain-staging and harsh-mid advice.[4]
If you want a clean bus compressor, related Kotelnikov / free-compressor list. If you want a vocal/drum style compressor, related Pro-C 3. If you want mastering assistance, related Ozone 12. If you want a synth, related Spire. This SKU is the free OTT plug-in.
FL, Ableton, Logic: Install v1.37, Then Pull Depth Down
- Download v1.37 from xferrecords.com/freeware
Mac .dmg (VST/AU/AAX) or Windows .exe (VST/AAX/VST3 per changelog). No iLok. Prefer this over a third-party “OTT pack.”[1] - If old projects miss VST3 OTT, read the 1.35 ID warning
1.33/1.34 VST3 IDs broke recall. 1.37 improves VST2→VST3 import. Do not delete a working 1.34 install until you know the session loads.[1] - Insert, then lower Depth before you mix into it
Production Expert: Depth is dry/wet. Time is global attack/release. Up/Down knobs scale those directions. Full synth technique is the related how-to slug.[4] - Stop before this page becomes Pro-C 3 or a compressor list
How-to-on-synths, Pro-C 3, free compressors, Ozone 12, and Spire are related slugs.
The Synth How-To, Pro-C 3, and Compressor Lists Are Out of Scope
This article does not teach OTT-on-synths step by step, does not review Pro-C 3, and does not rank free compressors. Those are related slugs.
As of this September 2026 fetch, Xfer’s freeware page still ships OTT v1.37. Recheck that table if you are reading later.[1]
If you need a free multiband compressor with a licence you can quote, start from verified software rather than treating an Ableton preset name as a paid mix suite. Plugg Supply free processing is 0; the free tier is ready non-premium archives only, and paid plans add processing and Telegram delivery.
