Thanks, MMario. Dunno why I'm perfectly happy using the 'NOT' operator on a database on my hard drive, but continue to forget it on the internet. Of course, actually I was hoping that someone had already done a list and crosschecked it, to save me the work. But I've gone through 'G' in the DT and checked against the MIDI site, so I have a fair list of tunes to get me started at least.
