Best Sound Card for Mac OS9.x, Seeking Opinions Options

[SONIC7]

I'm a newbie trying to determine which sound/audio
card would be best for my G4 867 SilverStreak. I
noticed the Creative SoundBlaster Live! for Macintosh,
but from what I've read, it's not really what I need
for MIDI etc. I've already got entry-level Steinberg
CUBASIS VST 2.0, and I want to record music via MIDI
first, then if all goes well, digital audio. I've also
got an old Korg DW-8000 which surprisingly is MIDI capable,
and an Alesis SR-16. I've discovered that I'm going to need
a decent sound/audio card. Some cards have MIDI ports and some
do not. Do the USB or FireWire cards also require a MIDI interface
like the MIDISport or MOTU Fast Lane MIDI 2X2??? So, if I were to
purchase a MAudo Audiophile 2496, would I also need the MIDISport 2X2???
Any advice greatly appreciated!!! TIA!!! Randall Prophet
