Note that this version of Radium does not run on Windows 7 or older. This was necessary to increase the DSP performance. However, it is possible to make it run on Windows 7 as well, it just requires some work to implement different code paths. Windows 7 or older will always perform a little bit worse than Windows 8 or newer, but both can be supported at the same time. Please let me know if you are using Windows 7 or older, and I'll try to make it run again.
Changes 7.7.71 -> 7.5.76:
-  Editor/MIDI: Fix recording chords from MIDI input
in step-recording mode. -  Sequencer: Fix seqblocks sometimes being placed at
wrong positions after moving more than one
seqblock. -  Faust: Upgraded from 2.70.3 to 2.81.2.
(Leo Fruijtier) -  Sequencer: Fix buggy display of graphics right
after loading a new song within the first 100ms. -  Sequencer: Fix grid not working in sequencer timing
mode when there is an editor block in the first
seqtrack. -  Windows: Use "WaitOnAddress" instead of
"WaitForSingleObject". This improves DSP
performance, but it's only available in Windows 8
and newer. - Preferences: Remove the "buzy loop" option.
 - Windows: Upgrade LLVM from V10 to V15.
 - MacOS/Arm: Upgrade LLVM from V18 to V19.
 -  Build: Many improvements and code quality
fixes.
