The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
Instruments, effects, sequencing, saving and loading of files/patches/refills, export of MIDI and audio have all been tested and work properly.
What does not
Instrument/effect labels are displayed improperly (text is going off in the wrong direction relative to the label graphic); menus are only accessible via keyboard (Alt + [x-]arrow); program crashes frequently with "Exception: Out of memory" type errors after moderate usage.
What was not tested
Control surfaces, importing MIDI.
Help figuring out these "out of memory" errors would be greatly appreciated.
