This is a bugfix release. It cares for the problem of stuck notes occurring when window scenes change while keys of a MIDI keyboard are pressed.

- Instrument volume window. - Monophonic bass. - Transposition functionality. - New adapters: Jeux d'orgues 2 Mini, Bureå Church Mini, Piteå School of Music Mini. These are well suited for mobile devices with small screens.

There is now an adapter for Pere Casulleras' meantone sample set of the Christian Zell 1737 harpsichord. On macOS and iPadOS 26+, users can choose whether screen keyboards are shown in the instrument view or in an own window. In the hardware settings, MIDI keyboards can be defined by manually specifying the channel number instead of channel detection by pressing a key. All MIDI actions induce an info display when executed. Bugfixes.

Bugfix: The installation function of the Gerhard Grenzing sample set adapter was broken in version 1.0. Bugfix: It was not possible to change the volume of the keys and knobs noises (for instruments that support these noises). Bugfix: MIDI actions for changing instrument and section volumes did not work. Other, minor bugfixes. New: Dynamic display of the reverb sections in the instrument settings view. New: MIDI action for temperament selection.

Adds support for two more sample sets: Bureâ Church of Lars Palo and Friesach of Piotr Grabowski. By making use of a table view, selecting an instrument for installing is now easier, and the same holds for defining MIDI actions. The Audiobus support was dropped because we did not manage to get it working well. Beginning with this version, on devices running iOS 17 / iPad OS 17 / macOS 14 and later, a subscription is needed to play all instruments with their full note range. Without subscription, the Jeux d'orgues 2 instrument is fully operational, while the other instruments are limited to a note range of three octaves on these devices. Read more about this at the Clavitudo support page.

Updated to Napo 6.2. - If the users wishes so, new recordings etc. are saved to iCloud drive instead of locally. - Various things can be controlled by MIDI. - Short octave functionality for all instruments. - Pitch range is enlarged to ±200¢, with fine-tuning by single cents. - Audiobus updated to v3.0.15.1. - Instrument adapter for Lars Palo's Bureå Funeral Chapel sample set.

Updated the download URLs for the Aragonese Procession Organ and the Grenzing Organ (ESMUC) sample sets. These can now be downloaded directly from the respective Clavitudo instrument page.

- Bugfix concerning the checkmarks in the temperament views. - The Marcussen/Moerdijk sample set can now be downloaded from the Clavitudo page. - There is now an adapter for the Kalvträsk Church sample set of Lars Palo.

This version adds adapters for four more sample sets: Eule / Szombathely dry and wet of Augustine's Virtual Organs, Jeux d'orgues 2 of Joseph Basquin, and Piteå School of Music of Lars Palo. Futhermore the app is upgraded to Napo 6.1: Enhanced scenes support (macOS, iPadOS), Audiobus support (iOS / iPadOS), and many more improvements that you can read about at the app support page (section Development History) and the Napo version history.

This is the first instance of Clavitudo that builds on Napo 6 and supports multiple instruments (there are adapters for four sample sets, for now). Large parts of the app framework have been rewritten. Users of previous versions need to redo the configuration.
