If you are looking for a wired sensor interface, you might want to
consider MidiTron. For those unfamiliar with MidiTron, it is my
inexpensive MIDI to Real World interface, available from
http://eroktronix.com. See this web site for more details.
If you are looking for wireless, soon I will be announcing public
beta testing of a new wireless version of MidiTron. This
announcement should come in the next two weeks.
