Convert a bunch of wave-files into renoise instruments: I had samples of a drum VST that I recorded by playing all the notes of it, I put all the wave-files in the same dir names "extract_drums_freeze_NAME.wav". This will slice them on silence, and create a drumkit instruments for renoise.

This is a basic system to modify a pi image & boot it in an emulator. Only docker is required. Instead of docker, you could also use chroot in create_image script. I like using qemu (in docker) so I can really test if the image will work. It constrains memory and runs slower. A chroot is much faster, but less similar to a real pi.

Quick overview of some techniques to ensure your personal data is secured. I happily will accept suggestions, if anyone can think of other things, and am also happy to explain or help with any part.

PERSONAL DATA SECURITY

Who Am I?

I'm a programmer with a personal interest in data-security. You can find me on github as konsumer.

Layers

Personal data-security is all about securing every layer, starting with the layers that enable other layers. Keep in mind the full path of things that are high-target items (money, devices - like apple/gmail, personal communication, social-networking) and keep in mind what each item allows access to. Do your best to secure every layer as well as you can, and quickly respond to indications of breach at every layer.

Gamecube controller (or DDR Mat) to USB MIDI. Install "Nintendo" and "MIDIUSB" in arduino library-manager. Use this on a programmable-USB arduino, like Leonardo.
#include "Nintendo.h"
#include "MIDIUSB.h"
// attach gamecube controller red wire on this digital pin
#define GC_PIN 7
// MIDI controls for each pad
int ctrls[6] = { 10, 11, 12, 13, 14, 15 };
// track previous state
