    Thumbs down Re: Midi drivers OSS vs. ALSA ?

    Windows Miditest4 32-Bits works with Wine... not all sysex messages but all other Midi.

    RME hdsp9632 has no OSS drivers yet... could not test Oss vs. ALSA.
    But Real WindowsXP sp2 vs. Linux+Wine YES!! TangoStudio1.1 64-Bit
    P4 1.6Ghz vs. i7 920
    same soundcard!
    Tested Wine with different Emulations W7, Vista, XP, 95.
    Linux is better...

    Miditest 4.6 seems to work better with W7 Emulation.

    Miditest 4.12 works better with 95 or Vista Emulation.

    Next Test will be USB interfaces.
