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?
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. :)
