Hello,
I have designed a midi controller with 144 pads. I use twelve CD74HC4067 multiplexers to drive my pads, plus pots and switches.
Result is fine with fast response.
My pads are pressure sensitive to retrieve velocity parameter. Each of them are wired with a resistor to form a regular tension divider. I have connected the 3,3V teensy output pin to every tension divider.
Do you think I could use the 5V out pin ?
This would give me a bigger range of values, without exceeding 3,3V max input of analog pins.
I have enclosed diagrams to make it clear. Diagram shows the wiring for 1 pad connected on the first mix channel.
Thanks
Emmanuel
