I use Windows 10 and MuseScore 4
1. Open any score with notes
2. Make sure all objects are deselected, then select a note - in my experience it is delayed by about a second
This also applies with objects other than notes. However, the delay is greatest with notes.

I hope that this is thing developers working on. On MS 3.6 there was option to use API -> ASIO. In MS 4.0 there is no ASIO to choose. And buffor minimal size is 1024 (I'm pretty sure if we can chose buffor lower, for example 64 or 128 latency will be much smaller).

For now I will write music in MS 3.6 and wait until ASIO or smaller buffer will be available in MS 4.0 (or 4.0.1) I hope it will be soon :)

Hello Guys

Before we see the fix for the ASIO system, I suggest a simple way to work around the problem (maybe not perfect, but it works and can be used as in MS3.6)

  1. I assume that anyone who has a latency problem has an external audio interface (FocusRite, Behringer, Steinberg, etc.)

  2. Connect the midi keyboard to the interface.

  3. Run any VST instrument in the background (e.g. Sampletank) and set it to play from the interface

  4. Set Musescore to be played from the computer's built-in sound card (e.g. High definition audio device)

  5. By typing music, mute the internal card with the windows mixer and listen from the ASIO interface.

  6. Playing with Musescore unmute built-in sound card :)

I know it's a bit weird and it's better that MS4.0 has built-in ASIO but you have to deal with it.

P.S.

Fortunately, I have an external Alesis mixer, so when I enter music, I mute the internal one and when I listen, I turn the sound back on.

I hope I helped and that you will be able to use MS4.0 fully before we see a working ASIO API.
