I like this gold coated triggers , i want that for my axo too....what do you think and how to DIY?
Gold coated Triggers
This are basically plated PCBs connected to jacks. The same effect can be done by touching the ends of patch cords or bare wires. The gold plating will make the surface last longer but this technology will also add any RF or electromagnetic energy from the environment that is also going through your body, into the signal too. To do everything this does, and do it MUCH better, use a FSR (Force Sensing Resistor). I make FSR modules under the Synthwerks brand and have a lot of experience with them. They are much better at pressure sensing and control than any capacitance method. They don't care about calluses, sweat, you can even wear gloves, and never need cleaning. With protective rubber mats on them (I use cut up mouse pads) you can even use drumsticks. These look pretty cool but I doubt that they work nearly a well as an FSR.
