Bob, he answered that on page two:

I'm using a Roland Juno-G for the KB input, with the USB-MIDI mode. A lot of synthesizers nowadays use that, rather than the old serial 38.4 Kbaud interface. It's a lot faster with USB of course, since that's 400 Megabaud.

I think the problem may be "stutter notes" from the keyboard.
