Riffer

Tools like Riffer are the secret weapons for all musical non-educated music makers.
Choose key, pattern lenght, number of notes, shuffle-mode, motion direction, sustain and tied notes and than...
hit the random button!
Or let Riffer hit it by itself e.g. every 4 bars. With the right settings the results are very usable.

Take three instances of Riffer (bass, pad, lead) and one or two instances of Playbeat, an other great tool by Audiomodern,
and you have a endless but not repetitive playing jukebox.;-)
5 Stars for fun and usability!
