UARP

User Guide

Ver 2.1

UArp is an innovative arpeggiator / sequencer suitable for many applications such as
Songwriting, Producing, Live Performance, Jamming, Experimenting, etc. 

The idea behind UArp was to create a live instrument that on the one hand uses the power of auto 
generated midi data, while on the other hand gives enough real time control to make it sound and 
feel like a legitimate professional musical instrument.
