Perhaps I'm wooed by fad ;), anyway, I read about using PS2 mouse and
keyboard should be better than using USB mouse and keyboard, perhaps to
shared IRQ issues or something similar. USB might be an issue?

I can see how the packet-based nature of USB could create jitter when
using a USB<->MIDI device. But how could some unrelated device like a
card reader create MIDI jitter? If you cannot keep your Envy24 card for MIDI I/O,
you might want to check out
the ESI MIDIMATE II. It's a minimal USB MIDI interface (it's really
just a cable,
no box) which works very well in my setup. This could open up a few more
alternatives for you, in case you decide on a device that would
require you to remove
the Envy24 card.
I've got 2 PCI slots and two Envy24 PCI cards. I guess that most other
PCI audio cards ship with a MIDI interface too, but I'm not sure if the
MIDI jitter will fit to my needs. Fortunately Jack2 from svn (jackd
--sync -Xalsarawmidi -dalsa ...) + my Envy24 cards do fit to my needs
regarding to MIDI jitter, but audio doesn't ;). I do have a Swissonic
USB device, but I avoid to use any USB device when making music, perhaps
I'm wooed by fad ;), I even disable USB card reader by my
session-handling-scripts (sudo killall -9 -w pcscd ;). No USB mouse,
keyboard or printer etc. here. To be honset, I didn't tested zthe USB
MIDI with current Jack2. On the topic of sound cards: can anyone recommend a
cheap external USB
sound card with many separate outputs (8 would be nice) and good Linux
driver support? Professional-level sound quality isn't paramount, just
lots of outputs. :)
Did you think of making several equal Envy24 cards (30,-€ at Ebay) one
virtual card? I didn't do it with my cards, but I guess this should
work, resp. I guess you're searching for USB, because you're using a
laptop? I guess there're Envy24 USB devices too and they are very cheap,
but full duplex etc..
