Ratings and Reviews
Amazing! One request…
This app is great fun! I’m loving the ability to strum my various synth apps with midi out! It’s so fun to use if you treat it like a live instrument.
My one request for the dev would be to add Haptic Touch for the newer iPhones. The app C. ARP does this very well, and kind of plays the same as the “Expression Performance Mode” in ChordUp but unfortunately that app, although great in its own right, doesn’t have midi out.
It seems kind of trivial, but there’s something about having that extra dimension that really makes you feel like you’re playing an instrument. It would make this already incredible app that much more amazing to me!
Prompt app support
I was having trouble because even when I had chord locking on, any adjustments to the chord reset when I play a different chord. Dmitry helped me realize that the reason it wasn’t working was that my Threshold (inside the Chord Locking setting) was all the way up. That resolved the issue, all within a couple hours of leaving my feedback here.
Two features I would really like:
- To be able to set any button to any chord, allowing me to play, for example, a G and G7 chord without changing a button back and forth mid-song. That would increase the functionality of this app for me by quite a bit.
- To be able to save these custom chord layouts.
I’d use this app all the time with these changes. I’ve honestly been looking for an app that allows music to be made like this for a long time, and I’m so happy it exists.
Developer Response ,
Hi! To lock a chord while chord locking is enabled you select a chord and the without releasing put the finger flat on the screen. The color of the frame around the chord type palette should become green. Check out this video https://youtu.be/gNW-bldmq0M
If you still have troubles with it please contact me by email firstname.lastname@example.org
Nice! But, please...
Wonderful app, but: 1) I am not a fan of this new grey UI and app icon. Would be great if you could choose to roll back to blue one. 2) I really need an option to name each of the pads or bars with their names accordingly to the chords used. Like A3, G4 and such. Thanks a lot!
