This is a drum and bass sequenceur in construction. This sequenceur can be used with the ableton APC mini, for those which don’t have it, use the keys +, -, Up, Down, Left, Right and Return of the computer keyboard. Automatons and presets have been added. To use automaton, create a folder containing them, click on the write button (don’t forget to record them in RAM before) and select the folder and the name of file (auto for instance), it creates several files beginning with “auto” and terminating by the name of the instrument. To read and load the automaton, do the converse (auto, even if the window is a save window). In future work, effects will be added and a way to select more instrument and play polyphonic sounds also.
