Ardour 9.5: Enhanced MIDI Editing for Free DAW

Posted on 25. May 202623. May 2026 by Max Noizefield

Ardour, the popular free and open-source digital audio workstation (DAW), has unveiled its latest iteration, Ardour 9.5. This significant update focuses primarily on substantial improvements to its MIDI editing capabilities, aiming to streamline workflow and enhance precision for producers and musicians alike. The developers have integrated several new features that address common challenges in MIDI manipulation, making the software even more robust for electronic music production.

One of the most notable enhancements is the introduction of chord editing and quantization directly within the pianoroll interface. This functionality allows users to work with musical chords more efficiently, providing tools to adjust and quantize entire harmonic structures with greater ease. Moreover, the update now supports opening multiple regions for editing simultaneously, a feature that greatly improves the flexibility when working with complex arrangements. Alongside this, the system can display reference or ‘ghost’ notes, offering visual cues from other tracks or regions to aid in accurate placement and composition.

Advanced MIDI Workflow and Visual Aids

The improvements extend to the automation workflow as well. Ardour 9.5 now includes stacked automation lanes in the pianoroll, which provides a clearer and more organized view of multiple automation parameters for a single MIDI track. This visual enhancement is crucial for detailed sound design and dynamic mixing. Furthermore, the DAW introduces a Cubase-style cross cursor, specifically designed to improve precision when drawing new notes or implementing MIDI automation. This refined cursor behavior ensures that edits are more accurate, reducing the need for constant corrections.

Beyond MIDI, the release brings several quality-of-life improvements. For instance, region automation control points are now visible upon hovering over a region, offering immediate feedback and easier access to parameters. The summary pane has also received a revamp; it is now thinner by default, featuring sharper overview rendering and conveniently placed zoom controls on the right side. This redesign aims to provide a cleaner and more efficient workspace.

Streamlined Plugin Management and Accessibility

Plugin management has also seen an upgrade. Users can now collapse plugin views located in the editor’s bottom pane, allowing for quicker access to frequently adjusted plugins without cluttering the interface. On the Mixer page, Ardour 9.5 introduces access to local and global track templates. This feature enables users to swiftly apply predefined processing chains by simply dragging and dropping a template onto an existing track, significantly speeding up the mixing and sound design process. Consequently, this allows for greater consistency across projects.

In a move towards enhanced accessibility and innovation, a community-contributed MCP (Multi-Channel Protocol) server is now available. This server facilitates controlling Ardour from a locally running large language model, with a primary use case focused on assisting users with vision impairment. This demonstrates Ardour’s commitment to a diverse user base. In addition to these major features, the 9.5 release also incorporates dozens of bug fixes and minor improvements, further solidifying its reputation as a reliable and evolving platform for audio production.
