Okay, looks like it might actually be the fonts I was using. The Episode 1/2/6 fonts seem to be a bit clicky and poppy, 6 especially. Disappointing, since I love the way the Episode 6 bank sounds, but maybe reinstalling it will help.
I figured out it was the fonts while going through all of the default fonts and listening closely. When I realised that the Ep 6 selection sound always had the same clicks at the same time, I twigged that it might be the font itself, not the speaker. It just
sounds like the speaker's knackered.
