still need answers to these two questions
how many vsts do you add to the project?
does this latency issue occur after you add one more vst?
bandcoachsorry, both of you are not even remotely close to the current problem, Which, while RAM-based, is not an issue with the usb ports being at one speed or another. Nor is it a soundcard the internal soundcard the issue has absolutely nothing to with the MIDI data processing or any latency que May Be Incurred due to other problems in the the / daw / etc ....
