I've been having a fight with Max4Live recently about using midi devices. I'd like to make a gigantic patch which integrates all my control surfaces, and replaces lots of the automap functionality with something that fits my playing style better. The problem is:

• m4l replaces max's midi functionality with its own driver, which takes midi from the Live channel the device is on.
• so you can't use multiple devices in a patch. At least, you can't differentiate them.
• a workaround would be to put each device on a different midi channel, and then separate the midi data inside the patch.

ChaoDependant installed Final days of testing, and doesn't everything all seem to go wrong at the end!

It turned out that when the high power LEDs are running, they drag the supply voltage down by about 0.2V. Which would normally be OK, but the Hall sensors are giving voltages in the mV range, so the changing supply voltage gives a bigger signal than the actual magnetic signal.

Damn.

We tried a bunch of things, mostly involving big capacitors, but nothing worked really well.
