Hi all,
This is my first post, so I wanted to introduce myself and share a couple videos of a Moog Voyager being used with an app I recently released for iPhone. Arpist was designed to compliment synths that have no arpeggiator or sequencing capabilities, so for anyone who wished their Voyager had an arp, hopefully you will find this useful!

Cheers!
Interesting! What midi-interface did you use?
In the video, I was using an iRig MIDI adapter (http://www.ikmultimedia.com/products/irigmidi/). It has performed very well, provides MIDI Thru and has a micro USB jack to keep your phone charged. iConnect MIDI and Line 6 MIDI Mobilizer 2 work as well - basically anything that support Core MIDI and is made for iOS. Most of these devices came out before iPhones inherited Lightning, so I have to use a serial pin-to-Lightning adapter (purchased at Apple Store for $30 US).
Wow! What an outstanding gift to the synthesis community. If the videos haven’t already convinced you to put this on all your iOS devices, please take my word for it and download it. As of the writing of this post, it’s free.
Thanks JJ. You make it sting a little less that I sold my Kurzweil ExpressionMate years ago.
Wow, interesting! Thanx 
Haha - you’re welcome. Thanks for checking it out!
