	Audience response was really good, small venue meant that people could see when I changed crystals that the sound completely changed too. Used cassiterite for first time(!) - resistance very high (probably due to fluourite intergrowth) so v bassy.

Not much modulation evident after midway through (pitch or filter) but doesn't seem to matter, most change through cat's whisker manipulation, which is good. Forgot to take out tweezers, so manipulating tiny switches was hard. Forgot to hit record on zoom, but have a cassette from organisers!
