Last Spring I bought and built a MIDIsense board kit that worked up to the point of calibration: The red LED glows nicely, the green LED flickers in an avalanche of bits from the MIDIsense to the MIDI interface. MIDIsense software opens up, I select sensor #6, set Aftertouch note 64... and ... and the slider does NOT move. MIDI monitor shows a deluge of code pouring from MIDIsense. Apple's Audio/MIDI setup shows MIDIsense board connected to micro lite MIDI interface.
Meanwhile I have worked on other Ada projects learning about micro-controllers, etc.
Tried MIDIsense again today - no change. Didn't mellow over Summer.
PowerMac G5 PPC dual processor tower;
MacOSX v. 4.10
MOTU micro lite 5X5 MIDI interface (reputed to be solid, fine with my keyboards)
MIDIsense software v1.1
Tried numerous resistor values for R106
Power supply 12 Volt DC, positive center tip (brand new from Sweetwater Sound, works fine with M-Audio Axiom 25 controller, aslo tried batteries)
Metered resistance at different light levels on photocell, seems perfect
Four white dip switches on MIDIsense board all set to OFF (like your picture)
Now, this sounds like pilot error, but my very experienced friendly electronics Guru built his own 'MIDIsense' using parts he had, and obtained the same results. (Late model Dell high end computer) He thinks it's a surfeit of output from the MIDIsense. Too much of a good thing.
Hope someone can help, explain how to fix or why it cannot be?
