Still got my Atari Mega ST4, and the old Cubase for it (dongle and expander ports and all!). I STILL have trouble getting timing as tight on USB MIDI interfaces as I got on that old thing....!
I used to sync it up to a cassette recorder with SMPTE, lay down audio on left track, SMPTE on the right (I used to do a lot of MIDI tracks from audio) and the thing locked up like a champ. Who says you need a guard track?!
Never have liked what happened to Cubase after VST5.... It's taken to SX3 to get back many of the MIDI functions I took for granted, and it still is buggy for a lot of basic MIDI stuff. I still tend to do all my preproduction in VST5 on OS9, render to audio, and mix on the newer stuff if it's only audio.
But every time I get frustrated, I take a peek at my old Dr. T's manual, and then I feel much better!
