The sync input on the RK008 has different settings you can use to slave it to a clicktrack. Here's an example on how to get that done with basic devices on @realitybytesyoutube
PS: I also mention using HairlessMIDI for linking up complete MIDI communication to a DAW via the RK008 usbserial port, here's the link to that project for various Platforms (PC, MAC, Linux)

And - It also seems the #RK008 syncs very, very nicely via SYNC24 / #expertsleepers Silentways VST Plugin if you want to stay in the audio sync route instead. Be aware though that this method is for syncing only and does not add your RK008 to the computer as a MIDI I/O device which can be used to record and send MIDI data.
