StepPolyArp

Midi Step Polyphonic Arpeggiator

for iPad with iOS v5.1.1 or later

StepPolyArp is a real-time Midi arpeggiator to control Midi instruments, sequencers like Logic, Cubase, Live, and all other Midi sequencers, or even other virtual instruments installed on the same iPad. The arpeggiator can automatically generate melodic patterns from notes or chords played in real time.

Although, StepPolyArp is specially designed to operate in Midi, it has own internal sounds bank to use it independently.

SoundPrism Pro and StepPolyArp by ‪Audanika

This tutorial shows how StepPolyArp can be controlled via SoundPrism: MIDI notes are sent from SoundPrism to StepPolyArp, StepPolyArp generates an arpeggio and sends it back to SoundPrism.

Controlling an Oberheim FVS by Logan Mannstrane

The StepPolyArp iPad application hooks up wirelessly to a Windows or OSX computer. I currently have the StepPolyArp app talking with Logic Pro that then drives a Doepfer MCV24 to go from midi to CV and Gate. The Oberheim is being triggered in Unison for all 4 Voices on every step.

This time I sent the sequence live to a MOOG Little Phatty thats running thru a Freqbox, Ringmod, and a Bass Murf which in turn is passing thru the DAWs Direct monitor live with a u-he Filter with some delays and verb. Access Virus TI Polar is playing some pads in the back.

"Want to get arpeggiating in Logic Pro? There's two main ways to set this up inside Logic... but wait, with an iPad you can get hands-on thanks to StepPolyArp app. Darren Burgos shows how."

Darren Burgos - macProVideo

"I really love this Arpeggiator... StepPolyArp is really really well thought out. You can create a Pattern (16 patterns available / Preset) very fast, create Accidents, Random, Automations (Velocity, Modulation, Volume, Pan, Aftertouch & PitchBend). 11 "tracks" are available on the grid (you can set their MIDI channel independently). Read the specifications at the end of this post. Watch also the video demo... A Killer App!"
