			Couple of hours recording, mixing ewtowan samples with the more easy to use Ale & Cakes [[galena]] and Penstruthal [[chalcocite]]. Getting a bit more to grips with [[chaotic triangle]] again, super for bass. In minimal a gig setup, single volca and only 3 voices. Noticed quiet square this time was down to tiny adjustment in 1920's galena diode in the ladder filter.

			[a&c gal] noise (w/wo ladder) -> <- tri [pen chal]
			[ewt chalcop/py/etc] square -> ladder (xtal) ->

			Quality of life fixes and improvements before gig:

			* Sort cat's whiskers so the fit the bases properly - mount in threads somehow (raid B&Q plumbing)
			* Connectors for cat's whiskers are still really bad, crimp mini-pv connectors. Can these be left connected to save time?
			* Build [[chaotic relaxation]] module
			* Incorporate new galena diode
			* How to highlight crystals?
			* Record dx7 patches through transmitter/xtal radio for backing track
			* New field recording needed?

			==Another galena cat's whisker diode==

			This one is not quite as crusty as it looks, but I'll try and give it a clean and sort out a mounting base for it as it should be useful for live performaces. The galena crystal has somehow survived the ravages of time, but I'm not quite sure how to remove it - it doesn't seem to be mounted in wood's metal, but it's attached mechanically.

			Picked up another (extraordinarily cheap) cat's whisker on ebay, when you can get them as parts its much better. This one is not quite as crusty as it looks, but I'll try and give it a clean and sort out a mounting base for it as it should be useful for live performaces. The galena crystal has somehow survived the ravages of time, but I'm not quite sure how to remove it - it doesn't seem to be mounted in wood's metal, but it's attached mechanically.
