StepPolyArp Arpeggiator For iPad

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.

What’s New in Version 2.0

• New Midi engine improving accuracy
• Automatic chaining patterns
• Internal sound bank

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.
