This little dude is actually a midi VSTi that creates no sound but triggers other VSTis that opened in the D.A.W. It can generate 999 seeded arpeggios which driven by **chords**. You can set a unique speed, note's length octave range and diversity (ply) to each arpeggio. You can also switch between arpeggios with your midi keyboard and randomize arpeggios in live sessions. The arpeggios are always synced to the D.A.W's BPM and time signature so you'll always get automatic positioned results.
999 is free. Enjoy!
