MelomethodicalPatternizationalogic! ™

It's a nice tool that I can swap up different arp styles between each measure so you can stitch together a nice harmonic scale. If there was a request, it would be to export a MIDI as a file rather than having to record the MIDI into another app which is a small inconvenience to have to set up—But I'm happy with it!


One of the most versatile arpeggiators on iOS. Maybe the best on iPhone (as most are for iPad). Great UI as well. And can you believe it all the advanced features have gone free now! If you have MIDI synthesizers you got to have this.

Great arpeggiator!

Note to music novices-this is not supposed to make sound. You use it to connect to a DAW or hardware synth that may not have an arpeggiator feature. Also a no brainer for a free one with this many features.
