seq

Lua based, MIT licensed midi sequencer with novation Launchpad as graphical interface.

A common limitation of hardware controlled sequencers is that they force you to use scales (major, minor, lydian, etc) or fixed steps (usually crouches). Of course you can change the scale or the steps, but you cannot define accidentals or very different rhythmic step positions (like play this note in 5 bars plus 1 crochet).

This sequencer “lubyk/seq” allows you to define notes and positions using some kind of binary notation thus allow access to 8 octaves and positions anywhere in 7 bars. The sequencer also supports individual loop lengths for each note.

Finally, it is written in Lua and should be easy to hack and extend.
