Yes it’s pretty fast, including on WAVs. I fail to see why you’d even bother to leave the units on autoplay/continuous to analyze anything. Seems like a waste of electricity. As an old school performance DJ playing house who would prefer to be on vinyl, you shouldn’t even need the moving waveform, BPM, or key, but you’re going to get them without even trying. Prime players will analyze each rapidly when you load each track, but it’s pretty extraneous for the sort of DJ you are. And what do you care what the BPM or key is of each track ahead of time when you can change both at-will soon after loading the track? There’s no point in you using that information to choose which track you play next. Anyway, your prior Rekordbox or Pioneer player database will get converted over when you first plug the drive in.
Oh. Just thought of something. Using Engine to generate a search-able database or strangely leaving your players on overnight for 8 hrs playing tracks to do it the slow way ahead of time would allow you to use the search function on the players later. But as an old school vinyl DJ who plans to use digital stuff and considering leaving the players on overnight playing tracks seems capable of analyzing all your relevant tracks, I’d say it would seem you won’t have enough tracks necessarily to even warrant using search at all. If you do plan to use search on the players, you have a bigger drive than you are letting on, and you do not have a Rekordbox or Pioneer-players-generated database already on said drive, then I’d recommend you just download Engine and use it to create the search-able database for the drive without analyzing the tracks. That’s all I use Engine for.
As for where I’m coming from, I’m still waiting for InMusic to let us hide the BPM and moving waveforms, though, as an old school vinyl DJ who could care less about that distracting stuff. Knowing the key is useful after I start cueing/playing the track, but not ahead of time and I don’t need it influencing my choice of tracks even in the browser. I believe we still do not have the ability to change the key of the tracks until it is analyzed, even if the latter is pretty quick, which is weird since hypothetically it shouldn’t need to know the key to change it.
My ownership experience of digital DJ media players (let’s call it a quest for fun): Numark Axis 8 → Vestax CDX-05 & Tascam TT-M1 → American Audio Radius 3000 & VersaDeck & Stanton CMP-800 & DJ Tech Usolo FX (all Hanpins and pretty neat) → Gemini MDJ-1000 (high defect rates, fragile, firmware still glitchy) → Pioneer CDJ-900 → Denon DN-HS5500 → Denon Prime SC5000 → SC5000M
Originally, the Prime players were nearly as problematic as the Gemini, but InMusic has brought them a long way. You will have the least hassle with the Prime Ms for playing on moving platters as the link, layers, and platter nudging all works better than old Denons, it is sufficiently good-sounding for house with keylock off (though all the others technically measure a little better even for non-demanding house with keylock off or at zero pitch), and you will get the best at-will extreme key change sound quality of any player I’ve used with going Prime. If you have the money and want vinyl-like mixing without having to use a computer or lug records around, take the leap. Other DJs will also be more interested in playing on your Primes than older or off-brand stuff if you take them to gigs if that’s something important to you.
