Yeah, the whole song is cached into memory. The speed of the media shouldn’t make a difference once the track is loaded.
I play 4/4 house and the grids are tight. If the grid was on a live track if expect it to sound like it’s coming in off-beat. What I get is a momentary pause in the audio stream as if the audio buffer has run out.
It’s not very press. Short jumps are okay (mostly) but it’s something that I never know how it will sound. Will it be glitch-free or will I drop a few frames of audio when I beat jump?
It happens to some and not others so it’s a curios one but then again, hardware differs inside on identical models due to components changing or becoming harder to find (chip shortages/discontinuation). I remember a bug that only affected the white Prime 4 (screen brightness couldn’t be turned down?). If there is a RAM variation then it could be an optimisation thing. Or maybe I’m expecting too much from beat jump? I always benchmark it next to software which are all seamless.
It’s not as bad as it used to be so I’ll investigate as to why I get any audio drop (it’s milliseconds but noticeable). Type of file, hardware revision number, firmware and media source could all play a part.
