Description

StepPolyArp is a Midi step polyphonic arpeggiator. The arpeggiator does not play any sound itself, it transmits Midi notes to a Mac or a PC to be used in combination with any sequencer, virtual instrument (VSTi, Audio Unit) or Midi synthesizer.

The arpeggiator can transform chords into sequences of notes played one after the other in several ways. A matrix polyphonic step modulate arpeggiated notes in time and pitch. The main controllers (velocity, modulation, panning, volume, aftertouch, and pitch bend) are also programmable through a step editor. The integrated keyboard automatically adapts to the selected musical scale.
