Enjoying it. Mostly

I like the simplicity of controls and how easy is it experiment.
I want to be able to choose a key that would change the chords (reorder and set to what makes sense in a particular key).
So instead of dm etc I could see 1, 3 etc.
“Contact support” in the app seems to be broken

ChordUp Simply one the best control out here

This controller makes making music fun and enjoyable
The developer has worked hard on this masterpiece

ChordUp -Play Chords App

Friend, What an incredible app! i'm having a blast with it. I'm always looking for some new interesting instrument thats simple, but fun.. its is pure genius in its approach, ease of use. Absolutely brilliant! I love the fact you have three different "types" of instruments included, Pad, String, and whatever that other one was, all cool. What really makes this app shine is the MIDI out, which I effortlessly send into synth apps, etc (Im relatively new to MIDI, so u made it real easy for the user to make a midi connection). Im having the most fun with sending the midi out to Korg Module and also to the Pure Synthesizer app, select a dreamy layered synth, set your app to sustain the notes and WOW! I thought I was in heaven hearing the angels playing an arpeggiated synth guitar. I was going to wait till Black Friday to see if it went on sale, I got apps mixed up and ended up paying full price. I'm not the least bit dissapointed, Son, you deserve every penny for such a well developed, well conceived app. I donr mind paying top dollar for stuff that works. Blessings! Rob "The Watchman"
