I have a cheap lap-top. I'm having latency problems when using midi. Can anybody suggest a sollution. Would a USB/Midi audio interface work? if so, who makes a good one.

Well, latency can usually be fixed by decreasing the sample buffer rate in Edit>Preferences. I don't know if USB is faster than MIDI, I wouldn't say so, but I've only ever used USB, which was on a pretty mediocre keyboard, and I worked great.

AFAIK USB is faster then MIDI, but indeed the most latency problems have to do with the soundbuffer and the soundcard drivers. I´d try to fix the problem there first.

I know my soundcard is cheap. I have a midi-keyboard pluged thru a M-Audio UNO Midi to USB interface (No audio or signal processing,there lowest ehd interface). When I hit a note there is a lag in time before I hear the note. Thank you all for your input.

Did you check the soundbuffer thing we mentioned above?

btw: You can maybe increase your soundcard performance by using the ASIO4ALL driver, which works with many cheap onboard soundcards.
