// What is this?
// =============
// The endless acid banger is autonomous pattern generator that spits acid-like
// note and drum sequences via MIDI.
//
// How to make this work?
// ======================
// Attach 10 buttons to Arduino (pinout specified bellow), connect serial TX
// to DIN-5 female socket (TX to pin 3 via 220 Ohm resistor, 5V to pin 4 via
// 220 Ohm resistor, GND to pin 2) and let it play.
//
// How does the interface work?
// ============================
// - "Play" button starts/stops the sequencer
// - "Gen synth1" button generates new melody for synth 1 from current note set
// - "Gen synth2" button ditto for synth 1
// - "Gen notes" creates new note set and regenerates the synth1/synth2
//   melodies from it
// - "Gen drum" generates new drum pattern
// - "Mem1-5" buttons switch to different patterns. If you hold one memory and
//   then press another one, the first one gets copied to the second.
//
// Have fun!
