Prerequisites:
* Knowledge in how to to install and use Arduino and Teensyduino to compile and upload the firmware. I'm not going in-depth on that.
* Basic soldering skills.
* A suitable synthesizer software. I recommend Thor on iPad (or in Reason).
* Knowledge how to use softsynths with MIDI and how to configure them to work with breath control (CC#2) or acquire patches that are already setup for this, like the presets that Bernie Kenerson has made for the Thor softsynth on iPad.
Short demo snippets using the TeensieWI together with Thor:
Hi cool project.
Are there any disadvantages using Teensy 4.0 or higher for this project or is it even possible, which is the latest version to use?
