PCI Midi port

HI all, new here. I am running 64Studio with an m-audio delta 44. The motherboard I have has no built in midi port, and the delta 44 also has no midi port. I've tried installing a couple crap soundcards that have midi ports on them, but they screw up the delta 44. Anyone know of a simple, PCI midi-port only card? I just need it for keyboard input, really.

Thanks Quentin. Do you ever

Thanks Quentin. Do you ever have latency problems with the USB midi device? I haven't used one, but I generally dislike USB devices, but if this works well, I'll pick one up for sure.

MIDI has such low bandwidth that I don't think there would be much of a difference in latency from a PCI card. One thing I would check is the output of 'lsusb' and 'cat /proc/interrupts' to make sure my USB device isn't sharing an IRQ with a resource hog like a video card. Now if you were recording audio through USB, it can be a bit slower than PCI. That being said, I have an Edirol UA-4fx and M-Audio Ozone that I use audio and MIDI at the same time and never have any issues. I run jack with at 128 frames and 3 periods/buffer. I read somewhere that 3 periods/buffer works better with USB because of some timer, not sure if that is still valid, but it works for me. :)

I have an inexpesive usb midi port from Edirol (Roland) that works great on my system. I believe that would be your easiest option.
