A step sequencer originally designed to run on the Raspberry Pi that can actually run on all Linux computers. The project aims to bring sequencing to the Raspberry Pi in a way that encourages hacking and exploration.

The structure enables the users to make their own way of iterating through a sequence of notes (Sequencial, random, reverse, etc.).

The original goal for this program is to be able to sequence a Korg MS20 Mini using a computer as cheap as a Raspberry Pi, even the Pi Zero that only costs $5.

The most important class here is MIDIDevice. It represents a MIDI device on which you can play notes using very simple commands with the MIDINote structure.

The StepSequencer class is a simple step sequencer designed to be as flexible as possible, hopefully enough to be used live, or almost live. It can iterate through the notes of a SeqNote vector using a NoteIterator.

A simple abstract class that can represent any way of iterating through a SeqNote pattern. The only functions it has to implement are :

• bool hasNext() : returns true when there is a note left to play
• int next() : returns the ID of the next note to play

Runs on Linux only. I might port it on Windows but it is not planned.
