A comprehensive feature list of PreSonus’ Studio One 4.5 Professional

Studio One Professional 4.5 newest features

Version 4.5 is a no-cost update for all owners of Studio One version 4. It includes over 70 new features and improvements that benefit both traditional recordists as well as contemporary nonlinear producers, many directly from customer feature requests. Chief among them:

Multi-processing enhancements for virtual instruments.

CPU load for using combined virtual instruments inside a Multi-Instrument has been reduced by a whopping 70% for Native Plug-ins and by around 50% for third-party instruments like Kontakt.

Redesigned Input Channel section

Studio One now features a revamped hardware audio device controller for software control of your PreSonus interface’s gain and polarity controls. And if your interface doesn’t have these controls, you get software gain and polarity control of every Input, anyhow!

Advanced Group management

Groups can now be nested, (great for drums) named, colored, and assigned to keyboard shortcuts for enable/disable. Furthermore, groups now have attributes for defining Edit Groups or Mix Groups, including Volume, Pan, Mute/Solo, and more.

I/O Setup options, import and export

Setting up an external audio interface has become a lot easier in Studio One 4.5. You can add any number of new inputs or outputs in a single step and re-order your I/O via drag & drop. You’re also able to import and your export I/O setups—great for mobile collaborators or users with multiple interfaces.

Streamlined Plug-in Manager

Managing huge libraries of plug-ins and virtual instruments in Studio One 4.5 is now faster and easier than ever before. The new Plug-in Manager combines all the tools for managing large systems in one place—hiding duplicate plug-ins or removing individual plug-ins from the blacklist now only takes a few clicks.

Note editing now goes way beyond MIDI

The Note Actions menu has been completely re-designed for fast, intuitive editing and composition, and includes new creative note editing options for Instrument tracks including Randomize, Apply Scale, Mirror, and more.

Chord Audition

The Chord Selector now has the much-requested Chord Audition feature, ideal for users who compose by ear.

Event and Track Locks

Individual Audio Events, Audio Parts and Instrument Parts in the Arrangement window can now be locked to prevent unintentional moving or editing. In fact, these locks are independent in the form of Time Lock and Edit Lock, respectively. A complete Lock for Tracks is available as well. No more accidental edits!

Enhanced audio and video format support

You can now export video in various formats with your mixdown embedded. We’ve also added support for variable-bitrate MP3, AAC, and ALAC, as well as mono export.

The length of this list speaks to just how much Studio One 4 Professional brings to your work on a general level. The best thing, however, is that it doesn’t feel like this many features – a sleek GUI and user-minded workflow help you command all of these features without even realizing it. If you’re switching over from a different DAW, Studio One assists your transition by enabling Pro Tools, Cubase, Logic, or Sonar keyboard shortcuts (or, you can even create your own).
