Studio Pro (formerly known as Studio One Pro) is a digital audio workstation (DAW) application, used to create, record, mix and master music and other audio, with functionality also available for video. Initially developed as a successor to the KRISTAL Audio Engine, it was acquired by PreSonus and first released under the name Studio One in 2009 for macOS and Microsoft Windows. PreSonus and Studio One were then acquired by Fender in 2021, which led to the product's rebranding as Fender Studio Pro in 2026. Since 2024, users who purchase and register a copy of Studio Pro receive a permanent license for the software, alongside one year of subsequent feature updates. It is also available as part of the Studio One Pro+ monthly subscription program.
History
Studio One early development and release (2004–2011) Studio Pro originally began development under the name K2, as a follow-up to the KRISTAL Audio Engine. Although development for this follow-up began in 2004, it transitioned in 2006 to a cooperation between PreSonus and KristalLabs Software Ltd., a start-up founded by former Steinberg employees Wolfgang Kundrus and Matthias Juwan. Kundrus was one of the developers for initial versions of Cubase, and established concepts for the first version of Nuendo. Juwan was the author of the original KRISTAL Audio Engine, wrote the specification for version 3 of the VST plug-in standard, and had also worked on multiple Steinberg products, including Cubase, Nuendo, and HALion. KristalLabs then became part of PreSonus in 2009, at which point the software was renamed to Studio One. The former KristalLabs logo was used as the basis for the Studio One logo. The first version of Studio One was announced on 1 April 2009 at Musikmesse, and released on 27 September 2009. The final update for version 1 (v1.6.5) was released in July 2011.
Versions 2 & 3 (2011–2018) Version 2 of Studio One was announced on 17 October 2011, and released on 31 October 2011 (alongside the 2.0.2 update). This release of the software introduced multiple enhancements, including integration with Celemony Melodyne, transient detection & quantization, groove extraction, multi-track comping, folder tracks, multi-track MIDI editing, an updated browser, and new plug-ins. The integration of Studio One version 2 with Melodyne was achieved via the creation of a new plug-in extension, known as Audio Random Access (ARA). This extension, developed jointly by PreSonus and Celemony, allows an audio plug-in to appear as an integrated part of the application. Version 3 of Studio One was released on 20 May 2015. The new features included an arranger track, scratchpads for idea experimentation, the ability to chain together different effects and instruments, MIDI note effects, new plug-ins, and the ability to use curves in automation.
Versions 4 & 5 (2018–2022) Following teaser images on social media websites in the preceding weeks, version 4 of Studio One was announced via a YouTube live stream event on 22 May 2018, and released simultaneously. New features in version 4 included a chord track (with chord detection, transposition and chord substitution options), a dedicated drum editing interface, expanded drum machine & sampler plug-ins, AAF-format import/export functionality (to exchange data with other DAW applications), and support for version 2 of the ARA plug-in extension. Almost exactly a year later, on 21 May 2019, this functionality was expanded further with the live stream announcement and simultaneous release of version 4.5. New functionality introduced with version 4.5 included input channel gain staging and phase/polarity options, a built-in plug-in manager, M4A (AAC/ALAC) support, video export options, new grouping options, RMS metering, pre-fader metering, CPU multi-core optimization, and expanded macro features, alongside a new add-on for batch audio conversion & processing. The release of version 4.6 was preceded by a launch party event, hosted by PreSonus at the Red Bull Studios building in London. Its release on 10 December 2019 included a re-designed and expanded version of the Ampire guitar amplifier and effects plugin (including new effects pedal options), a re-designed content browser, and new templates & macros for podcast production. Version 5 of Studio One, described as "ten years in the making", was announced via live-stream video on 7 July 2020. Features added in this new version included a full score editor (with features similar to that of PreSonus' notation software, Notion), a show interface focused on supporting live performances, MIDI support enhancements (such as polyphonic expression, custom ROLI device support, and the ability to use MTC & MMC to synchronize Studio One with external clocks). Version 5 also added support for recording in 64-bit floating-point WAV format, bringing the maximum precision for recording & processing to 64-bit/384 kHz and thereby making Studio One one of the highest-resolution audio production and mastering applications available. Version 5.4 of the software, released in September 2021, added native support for Apple computers with Apple silicon chips, thereby providing improved performance on such machines (which would previously have run the application via Rosetta 2 emulation).
