Hello everyone. I recently got a Teensy 3.2 along with a SpectraSymbol 500mm SoftPot, which I am hooking up with a breadboard. My goal is to make a ribbon MIDI controller that outputs pitch bend information.
I have some noob questions about this:
1. Am I hooking it up right? I have the middle pin going to A1, a wire from the negative pin to the teensy AGND, and a wire from the 3.3V of the Teensy to the positive pin.
2. What are the differences in the analog pins of the Teensy? Does it matter which one I plug into?
2. Do I need a pullup or pulldown resistor? I see conflicting answers everywhere I look about this. Can't seem to get it straight.
3. What is the best way to cut down MIDI information. With the Teensy running at its normal speed it generates a huge amount of MIDI messages. Right now there is some noise in the output, ideally there would be a way to smooth out the noise but not smudge really fast pitch transitions. I essentially want the ribbon controller to behave as a string on a stringed instrument: when you hold the string steady, there is no pitch wavering, but you can still instantaneously change pitch by putting another finger down. I'm having trouble achieving this with filtering.
4. My analog reading on my SoftPot seems to settle at around 180-280 when it isn't being touched. Is this normal? It shouldn't be a problem because I bought a long force sensor to put underneath the SoftPot for Aftertouch messages and also the ability to detect when pitch bend information should be sent, but I'm just curious.
If anyone has any insight I would appreciate it!
