Wait, yes, you can.
You Need to buy a 2.5 mm to 3.5 mm cable and an Adapter, which makes a usb port to a headphone and microphone Slot.
I know this works with Block Keeper, I don't know about other timers. If you Need any more help, you could ask DalDal on the Forum, he seems to know a lot about Computers and stackmats. (maybe also see his thread about how to connect a stackmat to a mac)
