hey,
I have a laptop with an MAudio firewire for live stuff. I also have a midi controller that i connect through the maudio to control synths and fx. problem is, the midi latency is very bad, and if i take it higher audio suffers.
also i like a lot the amazing line of dj style midi interfaces a lot of companies put out these days.
my question is this -
if i get a usb/firewire midi interface, and connect it directly to the pc over usb thus bypassing the old style midi port n the maudio, will i be getting the stable and fast midi responce i seek without having to worry about audio buffer issues and such?
thanks

There's no such thing as midi latency, a midi message is really really small. And the bus size of usb is absolutely sufficient.
The only latency that occurs is the time between pressing the key and the soundcard putting out the sound
So just latency from your soundcard.
So getting a better soundcard with good asio drivers will probably solve the problem.
Im running on like 6ms in ableton, wich is almost nothing
And be sure to get something firewire if you can, much more stable for audio transfers. Especially when you're also hooking up a usb harddrive etc.

umm thanks but that doesnt really answer my question.
i ALREADY have the firewire audiophile.
the question was if i get a usb midi device that doesnt interact in the hw world with the audiophile, if it improves performance.

Oh wait i misread a bit i quess 
When i directly plug my midi keyboard into my soundcard i have not latency issues atall
But you could also buy a midikeyboard that runs on usb, most of em also have a midi interface onboard so maybe that'll solve your problem

Generally there should be no latency issues over a midi card, a direct usb connection is better though, provided you know how to midimap... Try resetting your latency in your sequencer to a lower level to get a more accurate response from your keyboard. However that lowers your ram significantly which means you cannot play very many things at the same time. The m-audio firewire should have those settings on the hardware window.

If you're controlling software synths with a MIDI keyboard, whether that keyboard is connected via USB or a separate MIDI interface or via the MIDI interface on your soundcard is irrelevant; the latency between pressing a key and hearing the sound is absolutely determined by the latency on your soundcard.
Extra info (if you want/need it)
The lowest figure you can set the buffer size/latency to depends on all the other work that the computer, and particularly the soundcard, is doing at the time. ie. if you're writing a track and have a full set of plugins running in live, you are more likely to need a higher latency to prevent glitching than you are if you're just running eg. Ableton with a few clips and two or three VSTis, such as you would if you were playing a live set.
If you cannot lower your latency enough to get stable audio and acceptable keyboard response at the same time, you have only three options:
1: Reduce the amount of work the computer is doing, enabling you to lower the buffer size. You can do this by bouncing plugins to audio or using less CPU-hungry synths. OR
2: Replace your soundcard with one with better, more efficient drivers.
3: Replace or upgrade your computer with a faster one.

ok great thanks bro. i guess you too were saying the same rebel... so thanks to you both
i will stick with my current controller and try to reduce audio going ons.
