Happy to hear that!! It's actually not a tracker at all but rather a step sequencer, which IMO is a bit easier to get into, having less numbers and information all over the place... :)
I'd recommend checking out the video walkthroughs for learning all the different features in a nice pace.
The TD-3 should be syncable via the 'analog' sync option, this would involve getting a link cable (I recommend a GBC one) and a 3.5mm stereo plug and soldering the contacts to the appropriate pins on the link cable (the diagram in the guide)
If you are unsure how to do this there are a bunch of helpful people in the Discord. :)
