Plans

The table below specifies the more or less concrete short-to-mid-term plans.
Needless to say, all these plans are heavily subject to change.

Linux:
At the moment no application has a Linux edition.
However, the only remaining stumbling-block is the lack of low-level MIDI I/O handling.
Once this is implemented, creating Linux editions should be easy, particularly for the four applications already having Intel-based macOS editions, since the source code of these macOS editions can be used for Linux almost verbatim.

macOS:
Four applications are available in editions for Intel-based macOS. There are no ARM-based ("Silicon") macOS editions (nor are there any plans to develop these in the future), so on ARM-based machines you have to use Rosetta 2 to run the Intel-based editions.

Windows:
Nearly all applications are available on Windows as dual 32/64-bit installers (which automatically install the edition matching the operating system) and as 32- and 64-bit portable editions.
The exception is the Delta Framework application, which will remain available only as a 32-bit installer until further notice.
The Delta Framework application is behind the times in several other respects as well, such as:

• MIDI I/O handling.
• It is 'pre-mountainutilities.eu', thus links to the old Mountain Utilities web site.
• It doesn't provide advanced setup/desktop management yet.
• It doesn't come with a manual.
