I have a USB MIDI keyboard attached to a Windows PC (it is recognized as a standard MIDI device).
I use a virtual software synth VST-plugin (standalone or in a DAW software)
I also have a (rather new) soundcard with ASIO drivers.
Suppose that I play a note on the keyboard, what is the latency delay of the MIDI Note-On message before it reaches the VST-plugin ? Clearly it depends on the hardware, but can it be an issue (i.e. introduce a latency > 10ms) ?
Every information I found on Internet refers to latency that is introduced later: when the synth renders the sound on the audio interface (and in this case the ASIO drivers can drastically reduce the "final rendering" latency).
