A friend of mine was working closely with the Tactex company to try to
get them to make a useful musical controller using Tactex. Ultimately,

to done to make Tactex a good musical controller. Its got a couple of
key problems: very low refresh rate (i.e. latency), something like 50
Hz; and it can't detect two points of pressure closer than about 2cm.
He wrote a paper about the instrument he built using Tactex:
