timekeeping

[steel10string]

Hey, new user so forgive my cluelessness. I have a bunch of older Roland gear (like VS890, Juno D, old keyboards and rack stuff) and I am thinking of taking advantage of a real deal on a MOTU MIDI Timepiece AV and I am wondering if a.) it will be recognized by my old Roland stuff and b.) it is redundant or if there is anything other than a basic "click track" option inherently available to me within the Roland gear I've already got. Thanks
