We are curious to hear what you make.

Key Features

Improved Manual

The Studio manual has been reworked with a clearer structure and updated content. Navigation has been simplified so core concepts, devices and workflows are easier to find while working in the Studio.

Learn Section In The HUB

A new Learn section has been added to the HUB to help users understand the core Studio workflow. It provides structured entry points for learning the environment and basic production concepts directly inside the platform.

MIDI Import

MIDI files can now be imported directly as note regions. Drop a MIDI file onto the timeline to create a region instantly, or use the context menu on a notes player device track. This makes it easier to bring sketches from other tools into the Studio and start arranging without manual transcription.

Curated Apps In The HUB

The HUB now includes a Curated Apps section that surfaces a selected set of Nexus apps. These apps are built with the Audiotool SDK and run directly inside multiplayer DAW sessions. Developers can create browser based music tools that integrate with the Studio.
