sounds really cool. The 5000/6000 has hard disk recording and playback but I’m not really familiar with the SMPTE features, if it has any. I don’t need to use it very often and when I do I use the MPC. I’ll have to check the manual. I honestly mostly use it as a sample player for old, 90s and 80s sample libraries these days (which is probably how most people used it when it was new) but I’ve been thinking about actually recording an album on it for a while. It still has HDD recording (external AND internal, but I don’t remember if you can do both at the same time - I assume not, since it’s also stereo-only) and streaming from disk. There’s also an internal MIDI file player that could pretty much fill the same role as that SMPTE feature you’re talking about, assuming the internal timing is tighter than external MIDI (which i theoretically SHOULD be, but that doesn’t mean it actually is).
EDIT: nope, the word SMPTE doesn’t even appear in the manual at all. I guess it makes sense, it had already been downgraded from a standard feature to an optional addon in MPCs a few years before the 5000/6000 series came out. I could have sworn there was a SMPTE option for the 5000 that was standard in the 6000, but I was probably thinking of word clock.
